Curtain Gas
TM
Flow
The Curtain Gas
TM
flow must be optimized for signal stability and sensitivity. Start at a low value and increase the
flow rate until the signal starts to decrease. Reduce the gas flow until the signal returns to the maximum value.
Refer to
Source Parameters and Voltages
.
Heater Temperature
The choice of heater temperature depends on the type of sample being analyzed and the solvent used. If the heater
temperature is too high, the signal degrades. The maximum heater temperature is 250 °C for the NanoSpray
®
interface or 300 °C for the OptiFlow
TM
interface, but this is too high for most applications. For proteomics samples,
for example, we recommend a temperature of 50 °C to 150 °C.
The interface takes approximately 10 minutes to reach its working temperature after the system reaches a vacuum
ready state. Refer to
Source Parameters and Voltages
.
The following describes the heater temperature set-point relationship between the NanoSpray
®
interface and
OptiFlow
TM
interface
For a < 100 °C, b = 0.8a + 10
For a > 100 °C, b = 1.4a - 50
Where a = heater temperature for NanoSpray
®
interface
Where b = heater temperature for OptiFlow
