Gas Flow sets the flow rate in L/min of the nitrogen drying as. The flow required depends on the type of analysis (electrospray, APCI/APPI, or MM-ES+APCI), the LC flow rate, and the Gas Temp. In general, APCI/APPI mode requires less drying gas because the APCI vaporizer heater performs much of the drying function.
Minimum | Maximum | Typical | Default |
---|---|---|---|
3 L/min | 13 L/min | ESI: 10 L/min APCI: 5 L/min AJS: 5 L/min MMI ESI+APCI 5 L/min | 13 L/min |
