Accumulation of hydrogen in the MS and subsequent combustion

Hydrogen accumulation in an MS

All users should be aware of the mechanisms by which hydrogen can
accumulate, and know what precautions to take if they are certain or suspect
that hydrogen has accumulated. (See

.) Note that these mechanisms

apply to

all

MSs.

WARNING

The MS cannot detect leaks in inlet or detector gas streams. For this reason, it
is vital that column fittings should always be either connected to a column or
have a cap or plug installed.

WARNING

The MS cannot detect leaks in the valves for the optional JetClean system. It
is possible that hydrogen can leak into the MS from this cleaning system.
Always turn off the JetClean system and close the manual hydrogen shutoff
valve to the JetClean MFC and ensure good vacuum before venting the MS.

Table 2

Hydrogen accumulation mechanisms

Mechanism

Results

MS turned off

A MS can be shut down deliberately. It can also be shut down accidentally by an internal or
external failure. A MS shutdown does not shut off the flow of carrier gas. As a result,
hydrogen may slowly accumulate in the MS.

MS automated shutoff



valves closed

The MSs are equipped with automated shutoff valves for the calibration vial, optional
JetClean system, and the reagent gases. Deliberate operator action or various failures can
cause the shutoff valves to close. Shutoff valve closure does not shut off the flow of carrier
gas. As a result, hydrogen may slowly accumulate in the MS.

GC off

A GC can be shut down deliberately. It can also be shut down accidentally by an internal or
external failure. Different GCs react in different ways. If an 8890/9000/7890 Series GC
equipped with Electronic Pressure Control (EPC) is shut off, the EPC stops the flow of carrier
gas. If the carrier flow is

not

under EPC control, the flow increases to its maximum. This flow

may be more than some MSs can pump away, resulting in the accumulation of hydrogen in
the MS. If the MS is shut off at the same time, the accumulation can be fairly rapid.

Power failure

If the power fails, both the GC and MS shut down. The flow of carrier gas, however, is not
necessarily shut down. As described previously, in some GCs a power failure may cause the
carrier gas flow to be set to maximum. As a result, hydrogen may accumulate in the MS.
