These resources can help your process analyzer project stay on track


Industrial Sampling Systems offers in-depth analytical instrumentation material suited for anyone from a novice to a degreed engineer. Written by industry veteran, Tony Waters, it has more than 750 pages of material that balances theory and practical examples, making it useful both students as well as experienced engineers, designers and technicians. The book also provides readers with a sampling of information featured in Swagelok's 40-hour complementary process analyzer sampling system (PASS) training classes. It has more than 1,000 photos, drawings and tables, a symbols library, examples that illustrate calculations and how to apply equations, self-assessment questions and a glossary of terms. It is available for sale here or through Swagelok dealers.


Author Ian Verhappen says that just as we often overlook the infrastructure necessary to support other field instruments, the same happens to the protection of the analyzer system—the shelter and its design. But designing a suitable process analyzer shelter, even for a complex system, does not have to be an intimidating task. Then he follows up with a discussion of design considerations, when to use a case, cabinet, shelter of house for your equipment, designing the air exchange system, choosing the proper location, maintenance, dead zones, fire detection and more.

This PowerPoint is a summary of a presentation from the 2010 ISA Automation Week conference. It outlines in detail the problems with current process analyzer systems and suggests some solutions to improve the usability, efficiency and cost-effectiveness of process analytical systems and argues for a change in approaches to keep the techniques from becoming extinct.

The most important process variable on the process flow diagram (PFD) is often the process composition. Yet the installed and maintenance costs of analyzers have precluded their widespread use. Analyzers are typically only used in equipment and a stream where the composition has been both problematic and essential for product quality. Often overlooked are the process analysis and optimization opportunities afforded by more extensive use of online composition measurements. Greg McMillan and Pierce Wu explain how this control technique can eliminate the delays, limitations, failures and expense of analyzers. Direct link.


Discussion of how the New Sampling/Sensor Initiative (NeSSI), Gen 2 and the ANSI/ISA 76.00.02 standard can be applied to components mounted in tradition tube-and-fitting sampling systems, bringing the benefits of greater confidence in reported analyzer values, better reliability for process measurements and lower total cost of ownership.
