An Award Winning Analytical Technique
ION CHROMATOGRAPHY
1977 I R 100 AWARD PITTSBURGH APPLIED ANALYTICAL CHEMISTRY AWARD AND VAALER AWARD WINNER
Ion Chromatography (IC) analyzes ions in solution. IC is generally applicable to the separation and ppm-ppb detection of: INORGANIC ANIONS, ORGANIC ACIDS, ORGANIC PHOSPHATES, AMMONIA, AMINES, QUATERNARY AMMONIUM SALTS, ALKALI METALS, ALKALI EARTH METALS. Due to the fact that IC analyzers separate the ions in a sample and detect them from 1 % to trace level makes IC most appropriate in the following areas: (1) analysis in complicated matrices; (2) analysis of more than one ipn simultaneously in a sample; (3) analysisof ions at low concentration in a large concentration of other ions; (4) analysis of trace (ppb) levels of ions; (5) the analysis of several samples of a given type, then several of a different type, etc.; and (6) automated analysis.
