Application Note: Certifed Standard Solutions in Ion Chromatography
19 December 2007

Quantitative determinations in ion chromatography are based on calibration methods. Reliable calibration curves can only be obtained by using calibration standards that are of perfect quality.

Each Metrohm ion chromatograph is delivered together with a PRIMUS standard (Primary Multi-ion Standard; multi-ion standard for the determination of anions or cations) from Fluka. PRIMUS standards are not only used for calibration, but also for demonstrating that the instruments are functioning properly after installation.
