8.7.2 Device decontamination
• Set the evaporation temperature to 100 °C and the gas pressure to 2 bar (29 psi).
Pump the appropriate solvent through the system at the rate of 1 mL/min. The solvent will be de-
termined by the nature of the samples that were previously analyzed by the detector. If you do not
know the nature of the sample, ethanol is a good choice. Do not use solvents that can potentially
corrode the device. Maintain the flow and temperature during 3 hours at least.
• Clean the outside of the detector with a non-abrasive cloth. If necessary, a liquid such as
soapy water or ethanol can be used to remove stains or foreign material.
