The chapter describes the dew point/chilled mirror method in detail, which can create the impression that chilled mirror technology is mandatory. However, the scope of the chapter is broader: it allows water activity to be determined using different suitable hygrometric technologies. This distinction is particularly important for pharmaceutical laboratories evaluating water activity instruments for use…
Water activity is an important quality control parameter in many industries, especially when product safety, microbial stability and shelf life need to be evaluated. For QC teams, the key point is simple: a water activity result is only useful if it is measured with a suitable method, a reliable instrument and proper calibration standards. Why…
Since July 1, 2026, the regulatory requirements for Listeria monocytogenes in ready-to-eat foods have become stricter in the European Union. For QC, QA and food safety teams, this is more than a regulatory update. It is a clear signal that scientific evidence, shelf-life validation and documented product control are becoming even more important for ready-to-eat…
Microbiological testing, Microbial Limit Testing or MLT, for pharmaceutical finished products is essential, but it is also resource- and time-intensive. If you work in Quality Control or Quality Assurance, you know that traditional MLT procedures often take several days. What if you could drastically reduce this testing frequency, accelerate release times, and lower costs, while…
