Before performing maintenance work, turn the high voltage OFF from the
LabSolutions software.
If you do not turn the high voltage OFF, there will be a danger of electric
shock.
"LCMS Instruction Manual", "Turning the High Voltage ON/OFF"
When performing ESI analysis in which a halogenated mobile phase additive
is used, note the following:
In the ESI method, the analyte is heated to high temperatures. If the mobile
phase contains a halogenated compound such as chloroform, a corrosive gas
will be produced. Even a small percentage concentration of halogens in the
mobile phase can cause corrosion.
Use SUS tubes to connect the high performance liquid chromatograph to the
instrument. PEEK resin tubes do not have sufficient strength and should they
rupture, solvent may blow out.
Black particles may build up inside the ESI unit, and around the DL and the
heat block.
Because of exposure to corrosive gases, you may need to replace the following
parts at a shorter interval than specified.
