Less aluminum, less cadmium, less lead, less mercury... Move up to Fisher acids Why settle for "high purity" when you can get the world's highest purity? Choose the acids that offer the most by providing the least: FisherChemical Optima Acids for the lowest metal content and highest purity available anywhere...and FisherChemical TraceMetal Acids, for exceptionally low metal content and incomparable value. Fisher Optima Acids— The first acids good enough to be Optima FisherChemical's new Optima Acids offer the lowest metal content of any acids available. Most metals are present in concentrations of less than one part per billion, and many are in the parts per trillion range, as indicated on the certificate of analysis supplied with each bottle. Optima Acids are the obvious choice for environmental testing, plasma analysis, electronic research...any application that demands the utmost purity and precision. Each step in the creation of Optima Acids ensures the lowest level of metals in the acids you receive. Optima Acids are double-distilled in Teflon* or pure quartz stills at temperatures below the boiling point of the acid, then
packaged in Teflon bottles that have undergone a hot acid leaching process. And every stage of production and packaging takes place in Class 100 clean room environments. Fisher TraceMetal Grade Acids—exceptional value FisherChemical's new TraceMetal Acids provide extraordinary purity at a lower cost and are ideal for many applications that require extremely low metal content. TraceMetal Acids are produced with low metal content in mind; the competition's so-called "metal-analyzed acids" are simply lot-selected ACS acids. TraceMetal Acids far surpass the purity of these products., .and in fact are as pure as, or even purer than, many competitors' top-ofthe-line acids...yet cost considerably less. Careful sub-boiling distillation...ICP analysis... specially-treated containers designed to maintain exacting specifications...and a Certificate of Analysis with each bottle are the keys to TraceMetal Acid purity. Select Optima or TraceMetal Acetic, Hydrochloric, Hydrofluoric, Nitric, Perchloric, Sulfuric Acids and Ammonium Hydroxide. "Teflon is a registered trademark of E.I. du Pont de Nemours & Co., Inc.
