MOSH/MOAH LC-GC ANALYZER
Ingenieria Analitica offers an LC-GC analyzer for simultaneous determination of mineral oil hydrocarbons MOSH and MOAH in routine analysis.
Key component of this analysis system is the CHRONECT® LC-GC coupling developed by Axel Semrau®. It is coupled with Agilent Chromatography systems and appropriate software for the highly automated analysis of MOSH and MOAH.
Mineral oil residues are determined by coupling liquid and gas chromatography with subsequent flame ionization detection (LC-GC-FID). HPLC is performed upstream for separation of analytes from the matrix and separation of MOSH and MOAH.
The CHRONECT® LC-GC coupling ensures that HPLC solvent quantities incompatible for gas chromatography are effectively reduced without risking discrimination or contamination of analytes.
ADVANTAGES OF THE LC-GC SYSTEM FOR MOSH AND MOAH DETERMINATION
- equipped with two FIDs - simultaneous determination of MOSH and MOAH fractions in a single run
- analysis duration - results in 30 minutes, including GC detection, backflush and subsequent reconditioning
- direct LC-GC coupling - no risk of contamination
- no discrimination of volatile hydrocarbons
- twice the sample throughput
- highly automated process
- excellent reproducibility
- optimal sensitivity
- upgrades available, e.g analysis of PAHs or sterols
