an003548 fast analyses anions water with microbore columns using a compact ion chromatography system for reduced eluent use

AN003548 Fast analyses of anions in water with microbore columns using a compact ion chromatography system for reduced eluent use

Instrument Type: IC

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.

AN002338: Quantitation of per- and polyfluoroalkyl substances (PFAS) in aqueous samples by LC-MS/MS following EPA Draft Method 1633

Instrument Type: LCMS

PFAS are per- and polyfluoroalkyl substances. The chemical nature of the C-F bonds makes these compounds extremely stable. Hence, PFAS have been given the term “forever compounds”. This application note will present data for measuring 40 PFAS in fortified water samples following the third draft of EPA Method 1633. An MDL study was conducted in reagent water to demonstrate that equivalent or better performance can be attained using the Thermo Scientific™ Vanquish™ Flex Binary UHPLC system and Thermo Scientific™ TSQ™ Quantis Plus mass spectrometer.

AU002026: Determination of Tetrafluoroborate, Perchlorate, and Hexafluorophosphate in an Electrolyte Sample for Lithium-Ion Battery Production

Instrument Type: IC

This application demonstrated an improved method for the determination of tetrafluoroborate, perchlorate, and hexafluorophosphate in simulated lithium-ion battery production samples using a RFIC system with suppressed conductivity detection, and 2 mm versions of Dionex IonPac AS20 columns. This method significantly reduces eluent consumption and thus prolongs the life of the EGC as flow rate is reduced from 1.2 to 0.3 mL/min. The method has a linear calibration over the concentration range of 1 to 40 mg/L and was shown to be precise and accurate.
