Considerations specific to the ACQUITY QDa Detector
Power cord replacement hazard
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, with an additional 0.5% leak for the Standard instrument.
Flammable solvents hazard
High temperature hazard
Warning:
To avoid electric shock, use the SVT-type power cord in the United States and
HAR-type (or better) in Europe. The main power cord must only be replaced with one of
adequate rating. For information regarding what cord to use in other countries, contact your
local Waters distributor.
Warning:
To avoid leaks of materials that are biohazardous or toxins, follow these guidelines:
• 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
), determine whether any solvents you use that are not listed
are chemically compatible with the composition of the O-rings.
Warning:
To prevent ignition of flammable solvent vapors in the enclosed space of a mass
spectrometer’s ion source while introducing solvents, ensure that nitrogen flows
continuously through the source. The nitrogen supply pressure must not fall below 600 kPa
(6.0 bar, 87 psi) during an analysis requiring the use of flammable solvents.
Warning:
To avoid burn injuries, allow the metal parts in the interior of the source
enclosure, and the instrument’s source components to cool before handling.
