340CF ELSD
Section 4 Operation

4-14

Column Pre-Treatment

Chromatographic columns may introduce particles into the
mobile phase, which may lead to increased noise and blocked
fluid paths. It is recommended that the chromatographic column
be flushed with at least 10 column volumes before it is connected
to the ELSD.

4.5 Default Method

The ELSD’s default method (Method 0) is factory-set with run
parameters that typically produce optimal sensitivity across a
broad range of solvent types.

Spray Chamber (SC):

35 °C

Drift Tube (DT):

45 °C

Filter (FLT):

5

Calibration (CL):

20%

Gain (GX):

PREP

Full Scale (FS):

5V
