Join Agilent Senior Application Engineer, John Screech, live as he explores the critical concepts of vacuum.
We’ll begin with Q = P x S, the formula that explains EVERYTHING about the relationship between gas load, pumping speed, and pressure. John…
This Webinar focuses on the challenges in progressing from High Vacuum (approx. 10^-8 Torr) to Ultra-High Vacuum (below 10^-9 Torr) Pressure. Ion Pumps and Cryo-Molecular pumps are discussed in detail, as are the modifications to High Vacuum Gauges that…
Paul thanks for your reply. I have looked for information about these traps because I have two RMSH-2 traps and I thought about using one for the carrier gas (He) and the other for the FID hydrogen. Anyway, I'm going to buy the hydrogen trap. Thanks …
