Compressed air contamination can come in various forms, including particles, water, oil, and microorganisms. Non-viable particle contamination is specified in ISO 8573-4:2019 as one of the major contaminants in compressed air to be monitored. Troubleshooting particle contamination with Laser Particle Counters (LPCs) is the focus of this article.
Gaseous nitrogen is used in a variety of systems and processes in the food manufacturing and packaging industries. Often regarded as the industry standard for non-chemical preservation, nitrogen is an inexpensive, readily available option. Suited for a variety of uses, Nitrogen needs to be monitored for purity and potential contaminants. Depending on the type of use, the distribution channel, and the required purity levels, different testing plans should be implemented to ensure safety.
