Fully automated sample preparation for liquid chromatographic content determinations Summary Only liquid samples can be fed directly into a liquid chromatograph (LC). However, solid samples such as foodstuffs and tablets can be made injectable by homogenization, filtration and dilution with…

Quality assurance of biofuels Anions in an ethanol/gasoline blend (E85) Summary Quality and process control of biofuels both require straightforward, fast and accurate analysis methods. Ion chromatography (IC) is perfectly able to meet this challenge. Traces of anions in a…

Automated logical dilution for ion chromatographic determinations Summary For all investigated ions (Li+, Na+, K+, Ca2+, Mg2+, F–, Cl– , NO2–, Br–, NO3–, SO42– ), automated logical dilution yielded coefficients of determination (R2) better than 0.9999. Direct-injection recoveries for cations…
