Considerations specific to the SYNAPT G2 MS system
Solvent leakage hazard
The source exhaust system is designed to be robust and leak-tight. Waters
recommends you perform a hazard analysis, assuming a maximum leak into
the laboratory atmosphere of 10% LC eluate.
Flammable solvents hazard
Never let the nitrogen supply pressure fall below 400 kPa (4 bar, 58 psi)
during analyses that require flammable solvents. Connect to the LC output
with a gas-fail connector to stop the LC solvent if the nitrogen supply fails.
Warning:
• To confirm the integrity of the source exhaust system, renew
the source O-rings at intervals not exceeding one year.
• To avoid chemical degradation of the source O-rings, which can
withstand exposure only to certain solvents (see “Solvents used
to prepare mobile phases” on page C-3), determine whether any
solvents you use that are not listed are chemically compatible
with the composition of the O-rings.
Warning: To prevent the ignition of accumulated solvent vapors inside
the source, maintain a continuous flow of nitrogen through the source
whenever significant amounts of flammable solvents are used during
instrument operation.
