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.
Warning:
• To confirm the integrity of the source exhaust system, renew
• To avoid chemical degradation of the source O-rings, which can
Flammable solvents hazard
Warning:
enclosed space of a mass spectrometer's ion source, ensure that nitrogen
flows continuously through the source. The nitrogen supply pressure
must not fall below 690 kPa (6.9 bar, 100 psi) during an analysis
requiring the use of flammable solvents. Also a gas-fail device must be
installed, to interrupt the flow of LC solvent should the nitrogen supply
fail.
When using flammable solvents, ensure that a stream of nitrogen
continuously flushes the instrument's source, and the nitrogen supply
pressure remains above 690 kPa (6.9 bar, 100 psi). You must also install a
gas-fail device that interrupts the solvent flowing from the LC system in the
event the supply of nitrogen fails.

withstand exposure only to certain
any solvents you use that are not listed are chemically
compatible with the composition of the O-rings.
To prevent ignition of flammable solvent vapors in the
solvents, determine whether
