PL-ELS 2100 Ice

PL-ELS 2100 Ice Evaporation at Sub Ambient Temperatures

The PL-ELS 2100 Ice comprises an Integrated Cooled Evaporator in combination with the ‘evaporation gas’ technology to provide sub-ambient operation

The ‘evaporation gas’ is increased to compensate for the increase in relative humidity at sub-ambient temperatures

This approaches enables the PL-ELS 2100 Ice to operate at sub-ambient temperatures and as low as 10°C.

Even at ambient temperature the response of semi-volatile, low-molecular weight analytes can be poor.

So the PL-ELS 2100 Ice has been designed to operate at sub-ambient temperature to improve the detection of semi-volatile compounds

PL-ELS 2100 Ice Design Feature for Sub-Ambient Operation

Aqueous eluents can be removed at 15°C

Organic solvents (e.g. THF) can be evaporated as low as 10°C

The benefit of operating below room temperature provides maximum sensitivity for low-molecular weight semi-volatile compounds.

PL-ELS 2100 Ice Design Feature for Sub-Ambient Operation

The PL-ELS 2100 Ice can heat or cool rapidly, which reduces equilibration time.

• 35°C to 10°C in 10 minutes

• 15°C to 80°C in 11 minutes

Accurate temperature control of evaporator temperature eliminates external temperature effects

FOR VOLATILE SOLUTES

• Sub-ambient Evaporator temperatures required - 10-30°C

– PL-ELS 2100 Ice

• Gas flow optimised for sub-ambient temperatures and mobile phase

– 100% Water @15°C requires 2.2SLM of gas

• Compounds with high vapour pressures, low MW pharmaceuticals, pesticides, hydrocarbons

Sub-Ambient Applications

The S/N ratio for thermally sensitive compounds such as Acetanilide is improved at sub-ambient temperatures

In addition, the response of compound’s with high boiling points and high volatility, such as Alkanes, is dramatically improved.

Hence, ELSD temperatures need to be as low as possible, to minimise volatility effects.

Sub-Ambient Applications: Acetanilide (MW 135)

Sub-Ambient Applications: Alkanes

Additional Benefits of the PL-ELS 2100 Ice

Sub-ambient operation down to 10°C for maximum sensitivity to volatile compounds

Active heating/cooling provides rapid equilibration between analyses.

Improved accuracy of quantification.
