Alltech TLC Plates

Silver Nitrate Argentation TLC Plates• Allow separation of carbon-carbon double bonds on

the basis of their cis-trans configuration and degree of unsaturation

Argentation plates are prepared by impregnating Adsorbosil®-Plus plates with the stated percentage of AgNO3 solution. More double or triple bonds (unsaturation) give lower Rƒ values. These plates do not contain fluorescent indicator. Visualization is usually by charring with acid. The product is light sensitive and should be stored in the dark. Activate plates for 1 hour at 110°C prior to use for improved separations.

Note: All orders are custom-made to minimize the darkening effects of silver nitrate that occur during storage. Delivery is estimated at 1 week to 10 days after receipt of order.

Prep-Screen TLC Plates• Made with the 10-12µm spherical silica gel used for

Alltech prep-HPLC cartridge columns• Available in both Econosphere™ silica gel and C18

(reversed-phase) bonded versions

Prep-Screen HPTLC Plates help to optimize sample separation parameters for use in preparative HPLC. These plates allow a quick, inexpensive preview of sample traits in various mobile phase systems prior to HPLC analysis. The adsorbent is the same Econosphere™ silica or C18 used in Alltech packed HPLC columns.

• Kieselguhr is an inert diatomaceous earth support used by impregnating with other materials.

• Surface areas of Aluminum oxides:

Cost Saving Tip

TLC plates and HPLC columns are made using the same basic types of adsorbents. Even though you use a different technique, you can obtain similar separations, and you can switch easily from one method to the other. Because of the starting material costs, it is often much faster and less expensive to use TLC to develop an HPLC separation method.

EM Product Selection Hints• EM plate coatings do not

contain a gypsum binder. They contain a patented, inert, or gan ic, hard-layer bind er that is chip and abrasion resistant

• F-254s indicates presence of a special acid-stable fl uorescent indicator

WhatmanReversed-Phase TLC Plates

• Separate both polar and non-polar com pounds by adjusting the sol vent system

• Effective for sep a ra tions of cis- and trans-isomers

In reversed-phase systems, the chain length of the hydrocarbon functional groups affects retention and the ability to accommodate the water content of solvent systems. In general, the longer the carbon chain, the greater the retention. It follows that a shorter chain length yields faster separations. Shorter chain lengths are more polar, i.e. more suitable to aqueous solvent systems.

CycloGraph™

Analtech CycloGraph™ A Radial Device for Preparative TLC Separations

• Ideal for Harrison Chromatotron and Analtech CycloGraph™

• Uses 15µm (average) silica gel GF with strong binder to allow cleaning and reuse of rotors

• Ready-to-scrape uniform plates

• Rotor spins at 720 RPM

CycloGraph™ II – Universal System

This unit operates using 100-240 V at 50 or 60Hz. The CycloGraph™ is CE marked and supplied with a US cord set, but also has an IEC 320 compatible outlet for universal operation. (Note: IEC 320 cord set is not supplied with the unit.)

The CycloGraph™ II System includes the instrument, Low-fl ow (0-15mL) Solvent Pump with Tubing, Rotor Scraper Kit, Built-in 4-watt UV254 UV Lamp, Drop-in rotor mount for easy set-up, instruction manual and one year warranty.

Other features of the unit are the convenient hinged lid with safety interlock, fi xed speed motor, touch pad control switching system and an enlarged tempered glass view port.

• Get fast effi cient separations - usually in 20 minutes or less

• Monitor eluting bands using the built-in low-profi le UV lamp

The CycloGraph™ System is a centrifugally accelerated device for performing preparative chromatographic separations. It combines the advantages of both preparative TLC and column chromatography and delivers fast, effi cient separations - usually in 20 minutes or less.

To obtain a separation, a solution of the sample is applied inside the adsorbent ring of the pre-cast rotor using a pump or hand syringe. The solvent mixture is then pumped through the adsorbent layer as the rotor spins. Centrifugal force separates the individual components because of their different affi nities for the layer and the solvent mixture. As the individual components/rings reach the outer rim of the rotor, they are spun off and collected in a special circular trough for retrieval and further testing.

Typical fl ow rates are in the range of 2-3mL/min per millimeter of adsorbent thickness. The inlet of the solvent metering pump may be switched from a weak solvent to a more polar solvent during a run. This allows compounds with a wide range of polarities to be separated. Use of a strong solvent at the end of a run removes strongly adsorbed compounds and allows reuse of the rotor. Use the built-in UV254 lamp to monitor the separation as it occurs. The separated substances which adsorb 254nm light will be visible against the fl uorescent green background of the rotor.

Plate Cutter and Kits

TLC Plate Cutter• Scores coated glass plates at

any position• Compact, portable, and easy

to operate

The scoring and cutting of glass plates is routine in many chromatography labs, either to economize on plate usage or to cut the plate following separation for further analysis.

The TLC Plate Cutter has a high quality carbide scriber mount ed into a movable plastic head. It is designed to produce optimal scoring on the glass surface of 20x20cm TLC plates with a total thickness (glass + coating) of 2mm. A smaller template is included with the unit for ease in cutting 10x10cm plates. The carbide scriber is easily replaced when there is a noticeable deterioration in cutting effi ciency.

Basic TLC Starter Kit• Durable, inexpensive

laboratory equipment• Practical, reusable, and

educational

This Basic TLC Laboratory Starter Kit contains all of the supplies necessary for the least experienced student or technician to complete an analysis using basic TLC techniques.

The kit includes a 20x20cm glass development tank and lid, tank liners, Silica Gel G TLC plates, sample spotters, a reagent sprayer, a disposable spray box, spotting template, sample dye mix and a basic instruction manual.

The solvents used for the separations are common laboratory reagents and are not provided in the kit. Also, due to trans por ta tion regulations, a spray reagent for analysis of samples other than the dye mix must be purchased separately.

Note About Sample Applications

Thorough drying of samples is a step that is often ignored but can result in development errors. If a small amount of solute is left on the plate it can interact with the development

system and affect the separation.

Many analysts assume the plate is dry when the solvent is no longer visible on the plate (5-10 minutes). However, depending on the volatility of the solvent and the quantity of sample applied, the drying time can be considerably longer. Generally, Rƒ values decrease as drying time increases until the dry state (stable Rƒ) is reached.

Plates can absorb moisture from the atmosphere during storage, so prior to sample application, all TLC plates should be heated at 120-130°C for about 30-40 minutes and allowed to cool in a desiccator. This ensures reproducible Rƒ values.

For additional information on the TLC Plate Cutter, request datasheet 7535U. This datasheet is also available on our website.

TLC Sample Streaker• For preparative TLC• Quantitative application of

large sample volumes

The TLC Sample Streaker is de signed to apply a narrow band (1mm wide) of sample solution to a plate up to 40cm wide. Without scratching the adsorbent layer, the streaker will apply sample in one-tenth the time required for hand spotting.

For an effective separation, the solution must be applied to the plate in a continuous band, not separate spots as in analytical TLC. This is accomplished through the mechanical action of forcing a syringe plunger downward as it travels across a sloping stainless steel bar. Complete instructions for use and calibration of this device are included.

TLC AutoSpotter• Produces compact,

uniform sample spots• Automatic shut-off• Speed and temperature

controls with indicator lights

• Heater with digital read out for rapid solvent evaporation

• Dispenses the entire contents of eigh teen 100µL syringes in 15 minutes

UV Equipment

In some cases it may be helpful to use a transilluminator to enhance the visibility of the fluorescent compounds. The bottom panel of the darkroom cabinet can be removed and the entire cabinet can be placed on top of the transilluminator surface. The Transilluminator, 365nm, allows the long-wave light to pass through the TLC plate and enhances the visibility of the fluorescent compounds. While optional for most TLC work, it can be helpful when additional contrast is needed.

Photo Documentation System

E-Series UV Lamps

Camera

Darkroom Cabinet

For Visible Light Photos – Digital Camera with Mounting Stand

For UV Photo Documentation – Digital Camera with Darkroom

For UV photo documentation, a developed TLC Plate is placed in the darkroom cabinet and flooded from above with the appropriate UV light. The flexible eyepiece is replaced by the snap-on cabinet adapter provided with the camera. The camera is placed on the adapter and connected to the lab computer via the USB port. A simple click records the image.

Using the visible light method with mounting stand to record the plate image, the camera is placed on the holder which is preset at the appropriate focal distance. A simple click records the image. The camera mounting stand is especially helpful in archiving old photos of plates because it allows adjustment of the focal length using the height adjustment of the stand. The camera stand provides a better light source for regular visible light photos.

The software program provided with the camera allows easy archiving and retrieval of the photo images. The USB port connection from the camera to the computer makes use of the documentation system fast and easy. The documentation process is very simple but provides long term, accessible data storage.

TLC Sample Recovery Tubes• Removes samples from TLC

plates by suction• Reusable and all glass

construction• Extract sample in tube

A vacuum is connected to one end of the sample recovery tube and pulls the sample into the tube and rests it against the frit. Then pass solvent through the recovery tube to extract the sample.

pH-Fix Universal Indicator Sticks• For general lab use• Simple application – four

indicator papers (6 x 5mm) are sealed to each 6 x 85mm stick

Timer• Times three activities at once• Large, easy-to-read display• Three distinctive alarms• Compact size, 3 x 3"

Strip-Mix for TLC Documentation• Removes sample as a single flexible film

for extraction• Eliminates silica dust associated with

scraping techniques• No water required

Strip-Mix is applied to a TLC plate after development. It binds the particles into a porous, coherent film which detaches itself from the glass spontaneously – without the use of water. The intact layer can be stored or the separated spots can be cut from the layer and studied individually. This makes Strip-Mix especially suitable for radiotracer studies.

Adsorbent Scraper• Choice of 3 blade widths for maximum versatility• Blade mounted in “easy-grip” handle

6mm – Small Spots, Ideal for Radial Chromatography and Linear HPTLC
