Sentry Equipment Corporation Blog How to Ensure SWAS Analyzer Accuracy During Layups

Your plant's steam and water analysis systems (SWAS) instrumentation is incredibly sensitive, with detection limits that can be hard to comprehend. One of the most commonly used Units of measurement in a power plant SWAS is parts per billion (PPB). One PPB is the equivalent of one inch in 16,000 miles or one second in 32 years. Limits on specific parameters are less than 3 parts per billion and it is not uncommon to observe concentrations of less than .5 PPB on a steam sodium analyzer.
