Testing water for beer production Brewing beer requires large amounts of water, which must adhere to strict alkalinity, hardness, and pH parameters to ensure uniformity in flavour and appearance between each batch. Alkalinity is introduced by carbonates and hydroxides in water, which raise and buffer the pH. Hardness, balanced to...Read More

Fast IC means high sample throughput on short columns with relatively high flow rates and strong eluents. In beer, sulfite can be well separated from sulfate and other anions within less than ten minutes on a Metrosep A Supp 10-100/4.0. Ion chromatography (IC) is a standard method for beverage analysis....Read More

Formaldehyde is volatile. Avoid evaporation during sample prep with Retsch’s cryogenic grinding at – 196 °C. The beverage industry tests plastic bottles for formaldehyde as part of their quality control process. This is usually performed on the preforms for the beverage bottles. Before the actual analysis can be done, the...Read More

It's clever, it lets you know once its exhausted of measuring. The decolourisation spreads along the electrode to reach the “end zone”, meaning it's reached its end of life. No treatment or regeneration required, simply replace it with a brand new one and continue measuring. Temperature measurement is also incorporated...Read More
