Silver ion chromatography using solid-phase extraction columns packed with a bonded-sulfonic acid phase.

open access: yesJournal of Lipid Research, 1989
Commercial solid-phase extraction columns packed with a stationary phase with bonded benzenesulfonic acid groups are readily converted to the silver ion form and can then be used for silver ion chromatography of lipids.

Simultaneous Determination of Nitrite and Nitrate in Milk Samples by Ion Chromatography Method and Estimation of Dietary Intake [PDF]

open access: yes, 2016
The presence of nitrate and nitrite in foods may be considered hazardous after ingestion in the gastrointestinal tract due to their reaction with naturally occurred secondary amines to form potentially carcinogenic nitrosamines.

ION EXCHANGE CHROMATOGRAPHY

open access: yes, 2023
Ion exchange chromatography is a chromatography process that separates ions and polar molecules based on their affinity to the ion exchanger. Ion exchange chromatography is probably the most powerful and classic type of liquid chromatography. It can also used for almost all kinds of charged molecule including large proteins, small nucleotides and amino

Separation of Nucleic Acids by Ion Pair Reversed Phase High Performance Liquid Chromatography (IP RP HPLC) [PDF]

open access: yes, 2019
Ion-pair reversed-phase high performance liquid chromatography (IP RP HPLC) is shown to be an effective method to reliably analyze DNA. IP RP HPLC is a much faster and safer alternative to conventional methods of DNA separation and quantification.

Chromium (III) complexes and their relationship to the glucose tolerance factor : a thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Chemistry at Massey University [PDF]

open access: yes, 1982
Two forms of the dinicotinate complex Cr(nic)2(H2O)3OH were formed which were yellow and blue, respectively. For the yellow form the nicotinic acid ligands were coordinated via the pyridine ring nitrogen atom but this complex was biologically inactive ...

Analysis of an Antarctic ice core by ion chromatography (Mg2+, Na+, Cl−, and SO42− content) [PDF]

open access: yesGeochimica Brasiliensis, 2014
This study presents the ion chromatography analysis of an Antarctic ice core (IC-3; 85°59’S, 81°35’W) and discusses Mg2+, Na+, Cl-, and SO42− concentration data.
