Contain waste streams
.Because the API source can accommodate high solvent flow rates, you
must make provisions to collect the waste solvent.
Provide adequate fume exhaust systems for the API source solvent waste container and
the forepump.
Your laboratory must be equipped with at least two fume exhaust systems: one
to vent the waste container connected to the Exhaust port (API solvent drain) on the back of
the MS detector and the other to vent the forepump exhaust. As described in the
Surveyor
MSQ Plus Getting Connected Guide
, route the (blue) forepump exhaust hose to a dedicated
fume exhaust system. Because the exhaust hose acts as a trap for exhaust fumes that would
otherwise recondense in the forepump oil, the hose should travel at floor level for a minimum
of two meters (78.5 in.) before it reaches the external exhaust system. Route tubing from the
waste container connected to the Exhaust port on the back of the MS detector to a second
dedicated fume exhaust system. Consult local regulations for the proper method of exhausting
the fumes from your system.
Do
not
vent the PVC drain tube (or any vent tubing connected to the waste container) to the
same fume exhaust system to which you have connected the forepump. The forepump
exhaust contains pump oil, which can seriously contaminate the analyzer optics of the mass
spectrometer.
Solvent and Gas Purity Requirements
Because the Surveyor MSQ Plus MS detector is extremely sensitive to solvent impurities, use
the highest purity solvents available. Use liquid chromatography grade or higher solvents and
buffers. Because deionized water contains chemicals that the Surveyor MSQ Plus MS detector
can detect, use distilled water.
The following table lists international sources that can supply high quality solvents.
