A powerful analysis is often the best way to solve problems from production. We provide you with the preparation of an analysis plan, adapted to your sample and the required information content.
PhysChem Analytics GmbH has several gas chromatographs, with various detectors like FID, WLD, MS.
An ideal method for the elucidation and identification of ingredients / additives of plastics or their composition is the coupling of pyrolysis gas chromatography with detection by a mass spectrometer.
The high-performance libraries (NIST and VW) make it possible to obtain very precise information about the compositions and the plastics or additives used in various samples.
Flame ionization detectors can be used to detect concentrations down to the ng / μl range.
We have a modern device (Anton Paar Abbemat) for detecting the index of refraction at different temperatures. This method is often underestimated, especially when used in combination with other methods.
Sample treatment is one of the most important influencing factors on the results of an analysis. Here are some examples that have been successfully applied by us:
We offer a step-by-step analysis of your sample in order to provide the most accurate breakdown of the source of the sample. By means of soxhlet extractors, additives, auxiliaries or foreign substances can be dissolved from solid samples with different solvents. Subsequently, the composition of the extracts can be more precisely broken down in a downstream analytical method such as, FT-IR spectroscopy or GC-MS.
This method is particularly useful in combination with structure-elucidating methods, FT-IR spectroscopy, or the further investigation using MS. Due to the low cost, this method is particularly favorable and can often contribute an enormous plus to the elucidation of the origin of a certain substance.
