TN138: Accurate and Precise Automated Dilution and In-line Conductivity Measurment Using the AS-AP Autosampler Prior to Analysis by Ion Chromatography

Instrument Type: IC

Samples with high ion concentrations require loading less volume or diluting prior to injection into an ion chromatography system to avoid exceeding the column capacity and to ensure that the concentrations determined fall within the calibration range.This Technical Note discusses automated dilutions using the Dionex AS-AP Autosampler with and without the Dionex Sample Conductivity and pH Accessory, reviews experimental data, and recommends conditions for obtaining optimal results.
