IntroductionThe unit is designed to do a number of jobs with-in your laboratory. Please read the instructionscarefully to ensure that you receive maximumbenefit from it. Also, be sure to fill out and returnthe enclosed warranty registration card. Wewould like to receive the information requested,and it will help us assure you of proper warrantycoverage.

Water Determinations by the KarlFischer (Aquametry) MethodDead-Stop TechniqueKarl Fischer Reagent (KFR) consists of a mixtureof pyridine, iodine, sulfur dioxide and methanol.KFR reacts with water on an exact volume-for-volume ratio. In an excess of KFR, the reactionchanges from yellow to dark brown because ofthe presence of free iodine. In the presence offree iodine, the conductivity of the solutionincreases dramatically. In an excess of water, thereaction changes from dark brown to yellow indi-cating the absence of free iodine. In the absenceof free iodine, the conductivity of the solutiondecreases.

5

The dead-stop aquametry technique is a rapidmethod of water determination which does notrequire a back titration with water. The solventis first titrated with KFR to the KF end point toeliminate all of the water from the system. Asample containing water is added to the sol-vent/KFR mixture in the reaction vessel. Themixture is then titrated with KFR to bring themixture back to the KF end point. The volumeof titrant used is proportional to the amount ofwater in the sample.

The Labindustries Aquametry Apparatus is aclosed, odorless, moisture-proof system for thedetermination of water by titration with KFR.The Labindustries Meter-Electrode is a self-powered conductivity meter which preciselyindicates the water and KF end points.

KFR Titre:mg (µl) H20

F = ml KFR

Mass (volume) of water in sample:mg (µl) H20 = A x F

Percent water in sample:A x F x 0.1

% H20 =S

Where:A = Milliliters of KFR required for sample

Checking AssemblyAfter assembly is completed and before checkingfor airtightness, allow the Aquametry Apparatusto stand for a few hours with KFR in the reactionvessel. This will dry out the moisture in the instru-ment itself. Check for airtightness. Remove theplug from the drying tube at the top of the buret.For this check, be certain that the plug is in thedrying tube which is attached to the reaction ves-sel.Pump KFR into the buret with the stop cock inthe closed position. Turn the buret stopcock to letthe KFR into the reaction vessel. The reagentshould soon stop flowing, assuring you that thereaction vessel is properly sealed and airtight.Now remove the plug from the drying tube whichis attached to the reaction vessel. KFR shouldflow into the vessel.

The above check for airtightness is necessary,because, should the apparatus not be airtight,ordinary moist air in the reaction vessel mightrequire as much as 0.1 ml to react with the mois-ture before an accurate determination can bemade.

Checking the Aquametry Meter-Electrode for ProperPerformanceRefer to the views of Aquametry I Apparatus(page 26) and Aquametry II Apparatus (page 27)in this manual.

1. Remove the Meter-Electrode from theapparatus and gently wipe dry the endwith the platinum balls.

2. The meter should read close to zero. If itis off more than a division from zero, readjust closer to zero by turning the zero set — the small, clear plastic, slot-ted screw head in the transparent plastic

face of the meter. The number of divisionsthe zero set can be adjusted is limited toone or two.

3. Touch a metal paper clip across the plat-inum balls on the electrode. The meter should read full scale 5, but the needle must not go beyond 5. Use the full scale locking adjustment in the rear of theMeter-Electrode to position the needle at 5 while the platinum tips are shorted with thepaper clip. If the meter needle reads 5 when the electrode is shorted, the instru-ment is OK.

If when shorting the platinum balls, the needle readsless than 5, and the full scale locking adjustmentcannot quite bring the needle to 5, the battery, RM-IR, should be replaced.

If the meter needle reads zero when the balls areshorted, remove the electrode by unscrewing theelectrode sleeve and pulling the electrode out of itssocket. Open the paper clip and short the electrode socket in the meter with the ends of thepaper clip. If the meter now reads 5, the meter isOK, but the electrode is defective and should bereturned to Barnstead International for repair.

Karl Fischer AquametryDead-Stop TechniqueThe “dead-stop” technique described below is rec-ommended by Barnstead International as an accu-rate, far more rapid and simpler method for waterdeterminations than others requiring back titrationwith water.

1. Place the TEFLON-coated stirring bar in the reaction vessel.

2. Screw the adapter assembly in place.

3. Add approximately 50 ml of the selected solvent to the reaction vessel through the sample port.

4. Turn on the magnetic stirrer.

5. Aquametry I — Turn the buret stopcock to the filling position. Hold one finger on the air-release hole in the rubber bulb and pump the bulb to fill the buret. Close the stopcock when the Karl Fischer Reagent reaches the desired level in the buret.

5a. Aquametry II — Turn the buret stopcock to the closed position. Hold one finger onthe air-release hole in the rubber bulb andpump the bulb to free the buret. Fill theburet past the self-zeroing point andremove finger from the air-release hole.This will return the excess KFR to the bot-tle.

6. Remove the water in the solvent byadding enough KFR to just turn the solu-tion color from yellow to dark brown.This is known as the KF end point. Note

and record the meter indication on theAquametry Meter-Electrode conductancemeter. You may titrate to any point in thebrown KF zone, provided that you alwaystitrate to that same end point in all subse-quent samplings in the series. Allow thesolution to stabilize at end point for at leastone minute before proceeding to the nextstep.

7. Standardize the water equivalence of the KFR. Normally, this needs to be done only once a day or when changing the KFR sup-ply.

a. Into the reaction vessel, still at the end point, pipet a weighed or accu-rately measured volume of pure water,usually 15 mg (15 µl), through the sample port. For greatest accuracy, weigh the pipet before and after dispensing to determine the exact weight dispensed.

b. Titrate the water to the same end point as in Step 6 (1 ml of fresh KFR equivalent to approximately 5 mg (µl) water).

c. Compute the KFR water equivalence, F. F = mg (µl) water added per ml KFR to return to the KF end point (meter reading before the water was added).

8. To the reaction vessel, still at the end point,add a weighed amount of your sample whichis of sufficient size to contain 20 to 50 mg(µl) water. A sufficiency of water is indicatedby the solution color change to light yellowand/or the meter registering below the KFzone.

OPERATION

16

9. Titrate the water as in Step 6 to the original end point.

10. CALCULATION: Calculate the water content of the sample as follows:

(A x F x 0.1)Water, percent= S where:

A = Milliliters of KFR required for titration of sample

F = Water equivalence of KFR as determined in Step 7(expressed in mg (µl) of water per ml of KFR) and

S = Grams of sample

Re Aquant®, a proprietary product of J.T. Baker Company, may be used instead of KFR. It has the advantage of having no disagreeable odor by the disadvantage of requiring two solutions. The second solution contains the sulfur component, and enough of the second solution must be used to provide adequate buffering capacity, i.e. 1 ml for each 5 mg (µl) of water in the sample.

Achieving Highest Precision andEfficiency

Adding the SampleA liquid may be introduced into the reaction vesselthrough the sample port by removing the pennyhead stopper. Be certain to keep the openingclosed securely at all times when it is not in use.

A powdered sample may be introduced into thevessel by unscrewing the vessel from the adapter,

exposing the conveniently large opening of thejar. Add the sample to the solution and rapidlyscrew the jar back into the adapter to avoid theentrance of moisture into the apparatus.Powdered samples may also be added by dis-solving them in solvent and introducing themthrough the sample port in the adapter.When working with several parts per million ofwater, one cannot expose the solution withoutadding several micrograms of moisture from theair. For such required sensitivity, the jar must notbe opened. Replace the stopper of the sampleport in the adapter with a rubber capsule coverand add the sample or standard using a syringeand attached needle. An easily available capsulecover is the stopper in any blood collecting tube.

OPERATION

NoteFOR AQUAMETRY I APPARATUS OWNERS:

During a titration, if the dual buret has been filled to the zero line of the 1 ml buret and more than 1 ml is required, close the stopcock when the Karl Fischer Reagent reaches the 1 ml calibration line. Turn the stopcock to empty the Karl Fischer Reagent back into its bottle, lowering the of level of Karl Fischer Reagent in the buret to the zero line of the 25 ml buret. Resume the titration, using the final reading of the 25 ml buret plus 1 ml for the value of A in the calculations. Thus, either the micro or the standard buret may be chosen without sacrificing the airtight integrity of the apparatus, extending the high precision and speed of the determina-tion throughout the entire range of the instrument.

18

TitratingAdd solvent to the reaction vessel until the sol-vent touches the platinum balls of the AquametryMeter-Electrode while the magnetic stirring bar isrotating steadily beneath the electrode. (Irregularstirring will cause erratic indication of the endpoint.) Add KFR until the KFR end point isreached. Add more KFR in a few minutes if theend point is not held. When the true end point isreached, it will hold for hours. To titrate anothersample, refill the buret to the zero line.

When titrating, either the reaction must be stirredor the electrode gently moved to remove polariza-tion products. The Labindustries meter is alwaysready to operate. No switch is required.

Add KFR slowly to prevent errors caused by rapidheating of the reaction. Keep the stirrer motorrunning at a constant speed. A change in stirrerspeed may shift the end point. Titrate to the samenumber of the meter dial, e.g. 44, and allow themeter to indicate that number for at least 15 sec-onds before considering the titration completed. Ifthe meter indication drops back to the excesswater side of the end point, the sample should beleft in the jar for a longer period before titrating. Ashifting end point may indicate that the apparatusis not quite dry. Letting the apparatus stand withKFR in the jar will dry it out, since KFR is a veryeffective desiccant. A shifting end point might alsoindicate an interference with a substance otherthan water. Sometimes cooling the reaction ves-sel will eliminate the shifting end point.

Troubleshooting

20

Special Problems

Pretreatment of MaterialsAlthough water in most materials may be titratedwith KFR without difficulty, some materials reactwith KFR and require some pretreatment to permitan accurate water determination. Some of thesesubstances which require pretreatment are metalhydroxides and oxides, carbonates and bicarbon-ates, strong oxidants and reductants, boric acid,some metallic chlorides, ammonia, hydrogen sul-fide and sodium sulfide. To minimize side reac-tions, dilute the KFR to a titre of 1 or 2 mg (µl) percc. Methyl cellosolve and methanol are suitablediluents, depending upon the brand of KFR used.

Suitable SolventAlthough methanol is the most widely used solventin aquametry, some materials will not dissolve inmethanol and release the water to react with KFR.Select a solvent in which the material is soluble.We suggest methylene chloride for petroleumproducts, dimethyl formamide for biologicals,tetrahydrofuran for plastics, dioxane for bicarbon-ates.

Heating to Release WaterSometimes moisture may be released with difficul-ty and heating is required to speed up the releaseof water.

TROUBLESHOOTING

21

Aquametry Meter-ElectrodeAfter every 500 hours of use, wash the platinumballs in hydrochloric acid to increase the elec-trode sensitivity.

Check the Meter-Electrode for proper perfor-mance. See page 13.

BatteryThe Mallory RM-IR battery in the AquametryMeter-Electrode should last for one year withordinary usage. The back may be removed toexpose this battery for replacement by removingthe two sheet metal screws that secure it in posi-tion.

Karl Fischer ReagentKFR deteriorates with time. When measuring thetitre of the KFR, observe the mixture. Thereshould be no precipitate. If a yellow powdery pre-cipitate or a very fine black precipitate forms, donot use the reagent. To remove the precipitateleft on the glassware, rinse with methanol.Occasionally a few deposits of yellow will flakeout of the KFR and deposit on the walls of theburet. When excessive, rinse out the buret withmethanol.

General Cleaning InstructionsWipe exterior surfaces with a dampened clothcontaining a mild soap solution.
