| Environmental Grade and Environmental Grade Plus Acids Environmental Grade Starting with the best ACS acids available, Anachemia Chemicals applies a "sub-boiling" distillation process in quartz stills to achieve higher purity and very low trace metal content. These are Anachemia's Environmental Grade Acids, analyzed and documented for some 30 elements in the parts per billion (ppb) range. Environmental Grade Acids provide for superior stabilization of environmental samples to avoid any loss of constituents prior to actual analysis. Their consistently high purity also make them appropriate for many other laboratory applications. Environmental Grade Plus For even more critical applications, Anachemia offers double "sub-boiling" distilled Enronmental Grade Plus acids. Using Environmental Grade as a starting material, the "double-distilling" process removes virtually all remaining volatile and non-volatile impurities and trace contaminants. Packed in pre-washed Teflon containers for optimum stability, the unsurpassed purity of our Environmental Grade Plus acids makes them ideal for trace metal analysis. Please
