Start a plasma
16 Turn on the plasma by clicking the plasma on icon on the Main toolbar or pressing SHIFT+F5
on the keyboard. After a purge delay the igniter should start to spark and a plasma should
form. The Pump will then start to rotate.
The plasma emits heat, ozone and fumes which can be hazardous. Always switch on the
WARNING
exhaust system before lighting the plasma.
The plasma may not form on the first ignition attempt if the argon purge has not fully expelled
NOTE
all the air from the torch compartment. The plasma will take ~30 seconds to ignite. If it fails to
ignite, see Plasma not lighting details in the Help for further information. The plasma needs to
be turned on 10 minutes prior to analysis to allow it to stabilize. See Stabilization time details in
the Help for further information.
17 Adjust the pressure bars on the peristaltic pump for even sample flow. See "Adjusting the
pressure" on the pump tubing in the Help for further information.
18 Check that the Polychromator boost purge is on. Click on Instrument tab on tool bar. Click on
Status tab and under Purges click on Boost to enable Poly boost purge.
19 Leave the poly boost purging for at least 20 minutes prior to performing the wavelength
calibration.
It is highly recommended that the Poly Boost purge be on when performing a wavelength
NOTE
calibration.
If you do not intend to measure wavelengths under 190 nm you may wish to turn the Poly boost
NOTE
purge off. To do this, follow the procedure outlined in step 5 but select Poly Boost Off. Note that
the calibration may not cover the entire wavelength range.
