The evaporator gas flow is used to control the ELS detector’s evaporation process. The evaporator gas value is set according to the mobile phase composition, with higher gas flows (e.g. 1.6 SLM) being used for aqueous eluent compared to those containing organic solvents.
The higher the evaporator temperature, the lower the evaporation gas setting required (e.g. 1.0 – 0.9 SLM), regardless of mobile phase composition. Likewise, as the evaporator temperature is reduced to ambient and subambient temperatures, the gas flow needs to be increased to compensate (e.g. 1.6 – 1.8 SLM).
The evaporation gas range for both models is: 0.9 – 3.25 SLM (0.05 increments).
The default value is 1.6 SLM.
