The evaporator temperature is the most important setting on the ELS detector. It should be set according to the volatility of the compounds being analyzed.
If the compound is nonvolatile, e.g. sugars, then the evaporator temperature should be set to 80 – 90 °C.
If the compound is semivolatile, or has a low molecular weight, e.g. pharmaceutical drug, then the evaporator temperature should be set between 20 – 30 °C.
The evaporator temperature ranges for the ELS models are as follows:
G4260B/G7102A ELSD with non-cooled option | OFF, 25 – 120 °C (1 °C increments) |
G7102A ELSD with cooled option | OFF, 10 – 80 °C (1 °C increments) |
The default evaporator temperature for both models is 40 °C.
