Starting the TQ Detector 2-7
Running the TQ Detector at high flow rates
ACQUITY UPLC is run at high flow rates. To optimize desolvation, and thus
sensitivity, the ACQUITY TQD system should be run at appropriate gas flows
and desolvation temperatures. IntelliStart automatically sets these when you
enter a flow rate, according to the following table.
Note: Under low ambient temperature, high moisture, and high flow rate
conditions, condensation can occur in the instrument’s source.
Flow rate versus temperature and gas flow :
Flow rate
(mL/min)
Source temp (°C)
Desolvation
temp (°C)
Desolvation gas
flow (L/hr)
0.000 to 0.100 120 250 500
0.101 to 0.300 120 350 600
0.301 to 0.500 150 400 800
>0.500 150 450 900
