The GERSTEL-MOSH/MOAH Sample Prep Solution performs efficient determination of mineral oil residues in extracts of food, feed, body care products and packaging. The HPLC-GC-FID system from Agilent® Technologies is combined with the GERSTEL MultiPurpose Sampler (MPS) for fully automated sample preparation, introduction, analysis, and reporting.
In the LC, mineral oil residue is separated into the Mineral oil saturated hydrocarbon (MOSH) and mineral oil aromatic hydrocarbon (MOAH) fractions, which are transferred to separate GC columns. The dual channel GC analysis is performed in only 30 minutes.
The MOSH/MOAH Sample Prep Solution meets the requirements of the DIN EN 16995:2017-08 Standard and can be extended to perform epoxidation, used to remove interfering naturally occurring olefins, and ALOX Clean-up, used to retain and remove interfering long chain n-alkanes of plant origin.
The GERSTEL MAESTRO software, integrated with the Agilent Open-Lab CDS software, controls all method parameters for sample preparation, HPLC and GC. The entire workflow is conveniently and efficiently processed under one integrated user interface and sequence table.
Batch processing of large numbers of chromatograms using standardized conditions ensures high throughput. Predefined integration intervals for standard alkanes are clearly displayed and can be adjusted as required enabling fast visual inspection and reliable identification of standard peaks. Integration windows for MOSH and MOAH and for standards are selected by mouse-click.
Results are presented in one of several standard report formats that can easily be customized to meet your needs. Data can be exported in a variety of formats for further processing.
