"MOSH MOAH" resources

Whatever your sample preparation workflow requirements are, harness the power of LECO comprehensive two-dimensional gas chromatography (GCxGC) & time-of-flight (TOF) technology to solve the complex challenges of MOSH / MOAH Analysis.

We have solutions to introduce samples by liquid injection of your “fract and collect” preparations. Take advantage of fantastic sensitivity, best in class multidimensional separation power and instrument robustness to reduce the impact of sample matrix interferences and identify and quantify more with better than ever confidence.

Our GC×GC-TOFMS systems are at the forefront of Mineral Oil Saturated Hydrocarbons (MOSH) and Mineral Oil Aromatic Hydrocarbons (MOAH) analysis. The Pegasus BTX 4D offers unparalleled separation power, crucial for distinguishing between these complex hydrocarbon mixtures in food packaging and products. Its high sensitivity allows for detection of trace levels of MOSH and MOAH, meeting stringent regulatory requirements.

ChromaTOF software streamlines data analysis, providing automated classification of MOSH and MOAH fractions. This combination of advanced hardware and software makes LECO instruments indispensable for food safety laboratories, packaging manufacturers, and regulatory agencies dealing with MOSH MOAH contamination issues.

203-821-626 Discover unparalleled resolution and identification capabilities for analyzing food contaminated by mineral oil hydrocarbons (MOH). This application note details a powerful workflow to accurately separate and identify MOSH/MOAH fractions from comm...
401-952-737 The current analytical method for the quantitative determination of Mineral Oil Saturated Hydrocarbons (MOSH) and Mineral Oil Aromatic Hydrocarbons (MOAH) is LC-GC-FID, but the chromaticagraphic profile obtained is too often just a hump of unresol...
DE_Eur_SP_LD_CLS LECO's Pegasus BT 4D GCxGC-TOFMS system was used to review the complexity of contaminated food samples, providing superior chromatographic resolution and identification capabilities compared to the LC-GC-FID method.
LECO Pegasus BT 4D users, Dr. Susanne Kuhn, discusses their GCxGC work.
Improved sensitivity and group-type selectivity makes GC×GC ideal for MOSH/MOAH separations - saturated species can be separated from the unsaturated or aromatic ones. Hans-Gerd Janssen, University of Wageningen, Netherlands.
