The long road to acceptance: The slow adoption of ion chromatography in the pharmaceutical industry John Welch, Associate Director at Butterworth Laboratories, provides his perspective on the ...

Quantitative structure-retention relationships (QSRRs) have been a popular modeling approach in ion chromatography to predict retention time from molecular structures. It is often coupled with solvent ...

The herbicide glyphosate is the most widely used pesticide worldwide. Glyphosate and its major metabolite, aminomethylphosphonic acid (AMPA), have been frequently found in water samples. The widely ...

In this study, offline two-dimensional liquid chromatography-ion mobility-quadrupole time-of-flight mass spectrometry (2D-LC/IM-QTOF-MS) was used to analyze the different parts of G. longipes obtained ...

Lipidomic studies are often conducted using shotgun mass spectrometry (MS) or reversed-phase liquid chromatography coupled with MS (LC–MS). However, chromatographic separation offers several ...

Thus, a post column isotope dilution methodology has been investigated here for the reliable quantification of selenium species in wastewaters from a petroleum refinery. The separation of Se (IV), Se ...

It can be used for the quality control of honey and herbal beverage in enterprises or quality inspection departments. It also can be used in the rapid screening of food poisoning. Keywords Screening, ...

In this article, we consider ion pair chromatography, how it works, its strengths and weaknesses, how it compares to other ion chromatography techniques and its applications.

Ion-exchange chromatography (IEX) is a class of liquid chromatography used to separate organic and inorganic molecules, in particular biomolecules. In this article, we explore how the technique works ...

Calibration curve with and without ion suppression Figures 1 and 2 show calibration curves for quantification of ammonium ions over the concentration range of 0.5 to 20 mg/L by ion chromatography with ...
