AB165: Determination of p-Toluenesulfonic Acid in Water-Insoluble Drugs

Instrument Type: IC

Here, the convenience and accuracy of a Reagent-Free IC (RFIC) approach is applied to the determination of p-toluenesulfonic acid in water-insoluble drugs using an on-line matrix-elimination as described in Application Note 220, albeit with different columns and a different system configuration. (Note- The method discussed here requires Thermo Scientific Dionex AS-AP Autosampler with optional valves (one 6-port valve and one 10-port valve for sequential injection).
