Thermo Scientific TSQ Quantum XLS and TSQ Quantum GC Preinstallation Requirements Guide 23
Gas and Plumbing Requirements
As the user you are responsible for providing the correct gas supplies and regulators to operate
the TSQ Quantum XLS or TSQ Quantum GC system.
Your GC and mass spectrometer require high purity gases. Tabl e 10 summarizes system gas
and plumbing requirements and indicates where you will find additional information.
Table 10. Summary of gas and plumbing preinstallation requirements
Requirement Page
Argon gas
99.995% purity with less than 1.0 ppm each of water, oxygen, and total
hydrocarbons. The required gas pressure is 65 to 205 kPa (10 to 30 psi).
24
Helium gas
99.995% purity with less than 1.0 ppm each of water, oxygen, and total
hydrocarbons. The required gas pressure is 400 to 700 kPa (60 to 100 psi).
24
CI reagent gas
99.995% purity recommended. The required gas pressure is 65 to 205 kPa
(10 to 30 psi) for methane. The gas pressure of other reagent gases requires
optimization.
24
Plumbing
Single- or dual-stage high purity regulators that contain stainless steel
diaphragms. The regulator output pressures must be consistent with the
pressures listed in this table. Equip each regulator with a 1/8 in. Swagelokâ˘
compression fitting or equivalent to connect a 1/8 in. metal tube.
