By using specially designed stills, GFS were able to provide the highest quality acid available, containing virtually no trace contaminants whatsoever. Ongoing refinements to the acid distillation technologies allow us to keep the product purity in line with advancing instrumental capabilities and ever lower detection limits. With each step, the acid becomes more and more pure. GFS take the best acids and make them better! Today, these acids are used extensively all over the world in such analytical applications as stabilization of environmental samples, trace elementanalysis and numerous other applications which require consistently High Purity Acids.
