Beyond the normal process measurements (e.g., flow level, pressure, pH, temperature, conductivity, etc.) needed to check that production is on track, analytical instrumentation can track important variables that can keep difficult-to-control processes—e.g., fermentation—on track, in addition to monitoring fat contents in meats and proving authenticity of the ingredients you purchase, for example, virgin olive oil or seafood. Last year, we reviewed current state-of-the-art in instrumentation. In this article, we look at some practical applications.
