Drinking Water Testing Through our global network of testing experts and analytical equipment including chromatography (HPLC, GC, GC/MS) and atomic absorption spectroscopy (AAS, GFA, FIAS), Our goal is to provide test services as efficiently as possible to maximize our customers' profits. For more information about our services, contact one of our experts today. Drinking water contains a lot of chemicals, some of which are needed by the human body. Some drinking water is polluted and poses a threat to human health. Most of the substances in the water are not visible to us, and we can't even taste them. These substances include microorganisms such as viruses and bacteria, and other substances like salt, heavy metals, pesticide residues, and even radioactive pollutants. Therefore, for each of us, whether it is the manufacturer, supplier or consumer of drinking water, we need to pay attention to the safety of drinking water. Are you worried about the drinking water you purchased? Do you need a faithful test and analysis partner for the production and sales of drinking water? Alfa Chemistry can provide you with the most professional drinking water testing according to your requirements through advanced analytical equipment and mature analytical technology.
