LECO Solutions for MOSH MOAH

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.

  • Principles and Instrumentation of GC×GC and ToF-MS

    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.

  • Food Safety: A Journey Beyond the MOSH&MOAH Hump in Food Determination

    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 unresolved substances. However, GCxGC-TOFMS/FID is the most promising solution to characterize MOSH and MOAH in detail and to detect markers that can help identify and act on the source of contamination. Giorgia Purcaro [University of Liege] will introduce the challenges of MOSH/MOAH analysis and talk about what adding a GCxGC-TOFMS analysis to your process can do for your results.
