Industries are adopting methods to enhance analytical performance while minimizing ecological impact. In ion chromatography, using microbore columns with diameters of 2 mm or less reduces eluent use, cutting hazardous waste and improving throughput.This note highlights rapid anion analysis in water using microbore column, which significantly reduces liquid waste compared to standard bore columns. This method enhances safety and sustainability by minimizing waste production.Both chemical and electrolytic suppression techniques are demonstrated.
An ion chromatography-mass spectrometry (IC-MS) method to meet the analytical need of understanding the sample composition and degradation byproduct in simulated battery electrolytes. Integrating an organic solvent gradient, this method achieves excellent separation of many analytes allowing lithium-ion battery (LIB) manufacturers and researchers to gain knoledge to improve quality assurance, quality control and failure analysis processes to ensure the battery's performance.
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.
Demonstrates the determination of inorganic anions in drinking water by IC with built-in peristaltic pump for regenerant flow to a chemical suppressor.
This work demonstrates a five-minute analysis method to determine inorganic anions in drkinking water by an integrated, single-channel compact IC.
