PerkinElmer Clarus SQ 8 MS Series, Hardware Manual

Page: 42 / 184

Power Outlets Clarus MS: A minimum requirement of a power line separate
from the GC at 15 amps or greater.
Clarus GC: A minimum of one dedicated 120 VAC outlet at
20 A or one 230 VAC outlet at 10 A (minimum) is required
for the Standard GC. When the optional oven heater is
ordered, the outlets will be as indicated above. Additional
equipments, such as computers and printers, should be
connected per their specifications.
Gas Requirements
Carrier gases used with the mass spectrometer require a minimum purity of 99.999
%. Gas cylinders should be located outside of the laboratory whenever possible, and
should always be stored and operated in the vertical position.
CAUTION
ATTENTION
For all gases delivered to the mass spectrometer, always use
copper tubing that is free of grease, oil, and organic material. If in
doubt about the condition of your tubing, clean it before use.
Pour tous les gaz livrés au spectromètre de masse, utilisez
toujours des tubes en cuivre exempts de graisse, d'huile et de
matière organique. En cas de doute sur l'état de votre tube,
nettoyez-le avant utilisation.
Carrier Gases
GC/MS Carrier
Gases:
Helium
Minimum purity of 99.999% for methane, minimum purity of
99.98% for isobutane, minimum purity of 99.998% for
ammonia. Carrier gas tubing should be ultra-clean.
A number 1A (200 ft
3
) gas cylinder should be used for all carrier
gases with a high-purity, stainless-steel diaphram, two-stage
regulator. Filter through a moisture filter and/or hydrocarbon trap
and de-oxo filter designed for MS.
Gas delivery pressure to the GC should be 70 – 100 psi (483 – 689
kPa). Do not exceed 100 psi (689 kPa) on the carrier gas inlet.
