The Crystal Trace ultrapure water systems produce water for inorganic trace analysis. Such water is recommended for graphite AAS (atomic absorption spectrometry), ICP-OES analysis, ICP-MS, reagent preparation and ion chromatography.

Grade 1 water produced by these systems complies with ISO 3696, ASTM and CLSI standards.
