Fast and reliable analysis of drinking water by combining EPA method 300.1 Parts A and B in a single IC run.

Raman spectroscopy is ideally suited to rapidly screen for methanol contamination in spirits.

Precise online monitoring of peracetic acid (PPA) for beverage bottling requires a reliable stainless steel process analyzer.

Sodium lactate is a salt form of lactic acid used in many regulated industries—therefore an accurate determination of the lactate content is required and is already covered in several norms. One such monograph by the US Pharmacopoeia (USP) results in high accuracies and well-defined titration curves but uses titrants and solvents that are more costly than necessary. In comparison, the presented modified method from Metrohm requires a 1:1 mixture of water and acetone and uses aqueous hydrochloric acid as titrant, resulting in an estimated cost reduction of 40% per titration compared to the USP method (USP–NF 2021, Issue 2). Furthermore, the time needed for each analysis is reduced to just 12% of the USP method (excluding blank determination). This Application Note presents both methods to determine lactate content and shows the results obtained on an OMNIS system.
