New Multi-Multi-Method (GC-MS/MS) in oil

Detection of pesticides and plasticisers in oil in just one run

June 2020. In the analysis of oils, the issues of detecting plasticiser residues and pesticides often occur alongside. The former may get into the products during the manufacturing process, while the latter could enter products through their use in oilseeds. Combining both analyses was a complex task which has now been solved with a new Multi-Multi-method. This highly efficient method offers a range of advantages, such as high delivery reliability, expanded express capacities and an expansion of the portfolio of analysed plasticisers. Additionally, the method is more environmentally friendly and sustainable due to a significant reduction of the used solvents.

New method – many advantages

A Multi-Multi-method combines two or more Multi-methods in one analysis. By doing so, a large number of substances with different chemical and physical properties can be combined in one analytical run without compromising reliability or analytical quality.

The new Multi-Multi-method for pesticides and plasticisers in oil relies on gas-chromatography (GC-MS/MS). During the sample preparation, in particular, the new method offers significantly shorter process times from extracting the samples to measuring the test results. This, on the other hand, positively influences sample capacities, delivery reliability and, in relation, express capacities.

The new method also includes an expanded list of analysed plasticisers, while their levels of quantification were simultaneously lowered by a factor of 10 to 500 to 0.5 to 0.01 mg/kg. Thus, even the smallest contaminations by plasticisers which may occur in oils can be detected. Another important reduction of the new Multi-Multi-method is its environmental impact: the combined analysis of pesticides and plasticisers only uses 1 ml of solvents during the sample preparation process. This corresponds to a reduction of solvents of approximately 99% compared to ordering two separate analyses. At the same time, this method also results in cost savings, which are reflected in the sales price.
