Have you completed the free Agilent University Course: GC-0GEN-1001e - Gas Management Best Practices ? Many of the questions below are answered there in detail.
- Which gases will you be using? WHAT IS REQUIRED?
- Did you confirm that gases available are a supported configuration for install? HOW DO I KNOW?
- What is the purity of the gases?
- GC all gases 99.9995%
- SQ GC/MS 99.9995% He at <=120 psi
- TQ GC/MS 99.9995% He at <=120 psi
- TQ GC/MS 99.9995% N2 at <=120 psi
- CI: Methane 99.999% <=25 psi
- JetClean: H2 99.9995% <= 25 psi (a regulator is not included to go down from FID H2 to JetClean H2)
- Can I use gases with specifications that are not as good as the requirements? Why not?
- What is the source (tanks, generators, house plumbing) of the gases? WHY DO I CARE?
- Will the installer have easy access to the gas supply? DO THEY NEED TO?
- How far away will the gas cylinders be? WHY DOES THIS MATTER?
- Will you be connecting into existing plumbing?
- What should the terminal connection be before the installer arrives?
- All gases should have 1/8” Swagelok terminal fittings.
- Have you purchased the necessary tubing, fittings, valves, traps, etc? LINK?
