ion chromatography

Comparing suppressed and non-suppressed ion chromatography

Suppressed ion chromatography with conductivity detection is a powerful and sensitive technique to analyse charged ionic species, especially anions of strong acids. The chemically regenerated membrane suppressor Xenoic® XAMS can enable analysis of such anions down to levels of a few microgram per litre (part per billion, ppb).

Quantification of anions in water using an improved ion chromatography system

Anion analysis can be performed at several conditions, using various columns on different systems and still be able to meet official requirements. A common approach is isocratic separation with carbonate-bicarbonate eluents, and this example showcase how such analyses can be improved and streamlined with autosampler injections, continuous suppression and protected eluents.

Published routine method for quantification of anions in tap water and natural waters

Quantification of the seven common anions is an important part of water quality control. This published ion chromatography method is from a scientific paper that presents full validation data according to the ICH guidelines to meet the requirements of laboratories acting under the ISO 17025 accreditation.

ion chromatography

Generic method for isocratic separation of fifteen common pharmaceutical counterions

Many medicines and dietary supplements are bases that carry a positive charge, and consequently these small molecules are accompanied by negatively charged counterions. Such anionic excipients may influence the properties of the pharmaceutical formulation and can also influence the effect of the active ingredient since different ion pairs can have different dissolution rates or abilities to penetrate cell walls.

ion chromatography

Hydroxide gradient elution of organic acids and inorganic anions

Gradient elution is a powerful tool when aiming to separate many compounds having a wide range of different chemical characteristics. Hydroxide gradients are the most common approach in ion chromatography since they can be converted into pure water with nearly zero conductivity.

ion chromatography

Generic method for isocratic separation of ten common pharmaceutical counterions

Many medicines and dietary supplements are bases that carry a positive charge, and consequently these small molecules are accompanied by negatively charged counterions. Such anionic excipients may influence the properties of the pharmaceutical formulation and can also influence the effect of the active ingredient since different ion pairs can have different dissolution rates or abilities to penetrate cell walls.
