TSQ Quantum XLS and TSQ Quantum GC User Guide
Thermo Scientific
Solvent and Gas Purity Requirements
Use the highest purity solvents available. The TSQ Quantum XLS and TSQ Quantum GC
mass spectrometers are extremely sensitive to solvent impurities. Liquid chromatography
grade is the minimum acceptable purity. Higher grade solvents are preferred. Distilled water is
recommended. Deionized water contains chemicals and is not recommended. For a wide
variety of solvents and consumables, visit www.FisherLCMS.com.
The TSQ Quantum XLS and TSQ Quantum GC mass spectrometers use argon as a collision
gas. The argon must be high purity (99.995%). The required gas pressure is 135 ± 70 kPa
(20 ± 10 psig). Thermo Fisher has found that particulate filters are often contaminated and
are therefore not recommended.
Service Philosophy
Servicing the TSQ Quantum XLS and TSQ Quantum GC systems consists of performing
procedures required to maintain system performance standards, prevent system failure, restore
the system to an operating condition, or all of the above. Routine and preventive maintenance
procedures are documented in this manual.
The user is responsible for routine and preventive maintenance during and after the warranty
period. Regular maintenance increases the life of the system, maximizes the up-time of your
system, and allows you to achieve optimum system performance.
Only a Thermo Fisher Scientific Customer Support Engineer can perform services not
described in this manual.
Level of Repair
Thermo Fisher Scientific’s service philosophy for the TSQ Quantum XLS and TSQ
Quantum GC systems calls for troubleshooting to the lowest part, assembly, printed circuit
board (PCB), or module listed in the “Replaceable Parts”
chapter of this manual.
For mechanical failures: A mechanical assembly typically is to be repaired to the level of the
smallest item listed in the “Replaceable Parts” chapter of this manual.
For electronic failures: PCBs are not repaired to the component level except in certain cases of
fuses, relays, and so on. When these exceptions occur, component information can be found
in the “Replaceable Parts” chapter.
