Ion chromatography, ion chromatograph, bauxite ore, ore, alumina. This is an application that quantifies fluoride, acetate, formate, chloride, sulfate, malonic acid, succinic acid, and oxalic acid contained in the Bayer liquor produced by the process of obtaining pure alumina from bauxite ore (Bayer process).

This is an application that quantifies fluoride, chloride, phosphates, monofluorophosphate, and sulfates in toothpaste using anion exchange chromatography.

Adsorptive Organic Fluorine (AOF) is the sum value that covers a wide spectrum of organic fluorine. AOF analysis is an appropriate screening analytical method for PFAS in water. DIN 38409-59 conducts AOF analysis using combustion ion chromatography (CIC), which combines a pyrolysis device and an ion chromatograph – AOF analysis can be performed using Metrohm's combustion ion chromatography system.

Most organic fluorine compounds are assumed to be the total of all adsorbable organic fluorine (AOF) compounds in water. The measurement of AOF is simpler and faster than target analytical methods, and it is more sensitive than total fluorine (TF) measurements (which include all organic and inorganic F). Measuring AOF in water samples as an initial screening process allows for the screening of the actual amounts of organic fluorine compounds present. Following this, if indicated by high AOF concentrations, it can serve as a criterion for conducting target analysis of individual PFAS.

Manual preparation of elution solutions is time-consuming and poses safety risks, especially when handling corrosive substances, increasing the likelihood of human error. Automation effectively addresses these challenges. Automated generation of elution solutions ensures stable retention times, contamination-free safe operations, and reliable measurement results. Reagent preparation for analysis is almost unnecessary 24/7, allowing for a focus on analysis and saving time and costs.

We conducted the analysis by connecting the Metrohm ion chromatography (IC) to an Agilent triple quadrupole mass spectrometer (MS). This high-sensitivity method does not require sample extraction and can eliminate interferences from the eluent due to the Metrohm suppressor module. The matrix spike recovery rate for all target analytes at 1 μg/L was between 65% and 115%, and good results were obtained even with highly contaminated water samples.

The US EPA Method 300.1 (Parts A and B), ISO 10304-1, and ISO 10304-4 are conducted to ensure compliance when monitoring water quality contaminants that affect human health. In particular, disinfection by-products (DBPs) are associated with carcinogenicity and reproductive effects. EPA Method 300.1 Part A and ISO 10304-1 specify the requirements for quantitative analysis of major inorganic anions by ion chromatography.

Even in customized online industrial processes with multiple parameters and streams, monitoring using ion chromatography becomes possible. The 2060 IC Process Analyzer, based on the 2060 online analysis platform, is a highly flexible and perfect system suitable for online monitoring of ionic compounds in aqueous media at concentrations ranging from ng/L to the % order.
