Process Analyzer Sampling System Training (PASS)


Process Analyzer Sampling Systems (PASS) training is focused on overall system design. PASS training will study the detailed design of these functional modules and the selection of components to build them. See the course brochure for more details. 

If you design, construct, operate or maintain sampling systems, you know how important quality data is. Inaccuracy usually results from problems within the sampling system, not the analyzer. With our hands-on training, we teach you to tell the difference.

You can learn to diagnose and eliminate common sampling system design flaws that result in erroneous data by using engineering principles, formulas, and calculations rather than relying on guesswork. And you don’t have to do it alone. You’ll design a system in class, and apply what you’ve learned to your own process analyzer sampling system. Swagelok training teaches you in days what it could take years to learn on your own.
