Abstract
This paper deals with the problem of detecting benzyl methyl ketone (BMK), which is a precursor of amphetamine that can be synthesized in home labs. The focus of our work was to identify an improvement for the analysis of sewage introduced into the municipal sewage system. The sensors used to detect BKM in these systems are often clogged and therefore cannot function properly. In this article, a new method of detecting BMK and other chemicals in wastewater is presented. A system containing capillary polypropylene, hydrophobized with polysiloxane coating fibers was prepared. These solutions were used for continuous online measurements by ion mobility spectrometry. The use of pipes with a polysiloxane coating reduces the permeation of water and significantly increases the BMK permeation due to its high solubility in the polymer.

We propose a solution to the analysis in a highly contaminated sewage water system with a collection of samples via hydrophobized polypropylene membrane capillaries for ion mobility spectrometer (IMS) analysis or indirect analysis of collected samples in the lab with other techniques such as gas chromatography with a mass spectrometer (GC/MS)

Summary
Note: MDPI stays neutral claims in published mapsclaims and in with regard to jurisdictional institutional affiliations. Due to the difficult transport of water through polymer membranes, especially 3those covered with polysiloxane, they found an application in the constructed systems, allowing for direct collection of an analyte from an aqueous sample and its introduction into a detector [16,17,18]. In these methods, tests are carried out in flow systems. Acreates negative pressure pressure and accelerates the penetration of the analyte the tube
