Metrohm has announced that it is collaborating with Mitsubishi to produce combustion ion chromatography (IC).
The Mitsubishi Automatic Quick Furnace AQF-100 is combined with Metrohm IC systems resulting in a fully automated combustion setup.
Combustion IC opens up a range of samples, from viscous to solid, for fast and accurate elemental analysis.
A thermal oxidative digestion permits the determination of anions with IC of burnable substances.
The total content of halogens, in particular, and sulphur can be determined.
The samples are heat digested with an argon carrier gas and are then burned with oxygen where, for example, the sulphur species are converted into SOx and the inorganic halogens turn into hydrogen halide and halogen gas.
The elements are then trapped by an absorbent before being introduced into the Metrohm IC, where they can be quantified using a suitable anion column.
Combustion IC can analyse the total amount of organic and inorganic bound material, as well as free halogens, nitrogen, sulphur and phosphorous.
The halogens are determined as fluoride, chloride, bromide or iodide, nitrogen and sulphur, while the phosphorous are determined as nitrate, sulphate and orthophosphate.
Concentrations are typically in ppm range.
Application fields include the petroleum, coal or semi-conductor industries, which have the prerequisite to monitor-banned toxic compounds as they are sources of corrosion or poison.
Typical samples that can be analysed with combustion IC are oils, waste plastics, glass, electronics, PCBs and all kinds of gasoline.
