NOTE: See Appendix 2 for complete current supply requirements for the standard modules.
The power cable from the mass spectrometer is approximately 98 in. (2.5m) long and fitted with
National Electronics Manufacturers Association (NEMA) 5-15P power plugs. The NEMA 5-15P
power plug and corresponding outlet are shown in Appendix 3 Figure 5(b). NEMA 5-15P plugs
are rated at 15A and 120 Vac.
The power cable from the foreline pump box for the LC/MS is approximately 78 in. (2m) long
and fitted with a National Electronics Manufacturers Association (NEMA) 6-20 power plug. The
NEMA 6-20 plugs are rated at 20A and 220 Vac. The NEMA 6-20 plug and corresponding outlet
are shown in Appendix 3 Figure 5(d).
The power cables for the computer, monitor, and printer are approximately 78 in. (2m) long.
They are fitted with NEMA 5-15P plugs.
Systems shipped outside the United States and Canada are fitted with CEE 7/7 plugs which are
rated at 16A and 230 Vac. The CEE 7/7 plug and outlet are shown in Appendix 3 Figure 5(c).
Gas Requirements 1200L LC/MS
Nitrogen
A Nitrogen gas supply capable of providing up to 12L/min of gas regulated at 80 psi is required
as a nebulizing and drying gas. The nitrogen must have a purity greater than 99%, with less
than 0.1 ppm hydrocarbons, and less than 1% oxygen. The nitrogen should be dry, with a
−
40
degree dew point. Varian recommends the use of a nitrogen generator, or liquid nitrogen blow-
off to supply the gas. All nitrogen generators require regular maintenance to continue to perform
to specification. The nitrogen generator manufacturer should be consulted as to preventative
maintenance requirements of the instrument, and the schedule must be followed. Any problems
with the MS that are found to be caused by poor gas quality are not covered under Warranty. It
is the customer’s responsibility to conform to all regulations regarding the installation and
operation of the gas system.
Air
A compressed air gas supply that is capable of providing up to 2L/min of gas regulated to 80 psi
is required for negative ESI as a nebulizing gas. It is the customer's responsibility to conform to
all regulations regarding the installation and operation of the gas system. The air should be
clean and dry, with less than 0.1 ppm total hydrocarbons, including methane, and a
−
40 degree
dew point.
