Market survey/ procurement of two UHPLC-HRMS/MS (ultra-high performance liquid chromatography - high resolution tandem mass spectrometer) and maintenance contracts for the devices

Use The current procurement concerns two UHPLC-HRMS/MS systems. The one will replace current UHPLC-HRMS/MS system (Orbitrap Elite) used in analysis of controlled substances and the other will be set up for analysis of food products. The former system will be used for analysis of illegally imported substances like medicines, doping substances, illegal drugs, new psychoactive substances (NPSs), illegal chemicals and drug precursors. Data acquired with the system together with data from nuclear magnetic resonance (NMR) analysis will enable determination of detailed chemical structure of NPSs. For the system to be able to determine chemical structure in detail, it is essential that the system enables good chromatographic resolution, high mass spectrometric resolution and high mass accuracy both in MS and MS/MS. Essential part of analysis of aforementioned substances is dedicated software, which allows efficient and accurate analysis of LC-MS data. The system will be used in screening of aforementioned substances in cases where data acquired with other dedicated instruments is insufficient. For example, psilocybin mushrooms, biologicals and certain doping substances will be analysed with this system only. Analysis of biologicals and biological molecules requires high resolution and good mass accuracy, because for example identification of proteins and peptides is based on their accurate mass and amino acid sequence. Amino acid sequence on the other hand can be deduced from fragmentation data of either intact molecule or peptides produced by enzymatic digestion of a protein. The latter system will be used in analysis of food products. Primary focus of analyses will be on pesticides in addition to other contaminants found in plant based food products. While with current system used for the purpose, the number of different pesticides that can be analysed in one run is limited to approximately 250, the new UHPLC-HRMS/MS system will enable determination of virtually unlimited number of compounds. This is especially beneficial for analysis of organic products and products originating outside the customs territory of the EU as they may be applied with uncommon or even unexpected pesticides or substances. The new UHPLC-HRMS/MS system will increase Finnish Customs Laboratory’s overall ability to detect food fraud. Technology allows recognition of substance profiles, which would indicate dilution of a product or replacement of an ingredient. Because the technology allows measurement of molecular profile of entire product, it is possible to return to previously acquired data to detect changes in profiles and in that way track down possible introduction of harmful substances within a product.
