AN 002998: Determination of selenite and selenate in environmental waters by IC-MS

Instrument Type: ICMS

To develop a method to determine selenite and selenate in spiked environmental water by coupling ion chromatography (IC) with single quadrupole mass spectrometry

AN002748: EPA Method 1621 collaboration study_Combustion IC

Instrument Type: IC

Per- and polyfluoroalkyl substances (PFAS) is the collective name for synthetic fluorinated compounds. Here we describe our lab's results from the EPA draft Method 1621 multi-lab study results to screen for PFAS using adsorbable organic fluorine by combustion ion chromatography. The recovery of 4 types of PFAS from wastewater samplers are discussed. This method was found to be robust, precise, and accurate. Additionally, a technical note is included to describe tips and tricks for successful implementation of EPA Method 1621.

AN001055: Assay of Guanidine in Pharmaceutical Formulations

Instrument Type: IC

The goal of this work is to design an ion chromatography (IC) method for the determination of guanidine. A method that uses a Thermo Scientific™ Dionex™ IonPac™ CS20 cation-exchange column, electrolytically generated MSA eluent, and suppressed conductivity detection was developed to determine guanidine in pharmaceutical formulations. The method proposed in this application note was validated following the guidelines outlined in USP General Chapter <1225>, Validation of Compendial Procedures to meet the requirements of a validated guanidine assay.

AN000900: Determination of Phosphite and Phosphate in Ibandronate Sodium

Instrument Type: IC

The goal of this work is to design an ion chromatography method that uses a Dionex IonPac AS28-Fast-4μm anion exchange column, electrolytically generated KOH eluent, and suppressed conductivity detection to determine phosphite and phosphate in ibandronate sodium. The method proposed in this application note was validated following the guidelines outlined in USP General Chapter <1225>, Validation of Compendial Procedures to meet the requirements specified for phosphite and phosphate quantification prescribed in the proposed USP Ibandronate Sodium monograph.
