| Hankinnan lyhyt kuvaus | The object of the tender process is Triple quadrupole mass spectrometer ICP-MS/MS (later also “Equipment”). Basic use of a mass spectrometer is to analyze element concentrations in a sample based on the mass-to-charge ratios of the ionized elements. There are several different types of mass-spectrometers available that differ in methods of sample introduction and analysis type. The required mass spectrometer in this procurement is a triple quadrupole mass spectrometer: ICP-MS/MS The intended use of the triple quadrupole mass spectrometer is for the analysis of hard to determine radionuclides and trace element analysis in the semiconductor industry. Procured mass spectrometer must fulfill the requirements set for these types of analyses. A triple quadrupole ICP-MS (Inductively Coupled Plasma Mass Spectrometer) is a type of mass spectrometer that uses a combination of three quadrupole mass filters to separate and analyze ions based on their mass-to-charge ratio (m/z). The instrument consists of an ion source, a mass analyzer, and a detector. The ion source generates a plasma by ionizing a sample using an inductively coupled plasma (ICP) source. The plasma produces a stream of ions that are extracted and focused into a beam using a series of lenses and skimmers. The ions are then introduced into the first quadrupole mass filter, which acts as a mass analyzer and selects ions of a specific mass-to-charge ratio (m/z) to pass through to the second quadrupole. In the second quadrupole, the selected ions are further filtered based on their m/z ratio, and only ions of a specific m/z ratio are allowed to pass through to the third quadrupole. The third quadrupole acts as a collision cell, where the selected ions are fragmented by collision with a gas, typically oxygen, helium or argon. The resulting fragments are then analyzed by the third quadrupole, which selects ions of a specific m/z ratio to pass through to the detector. The detector measures the number of ions that reach it and generates a signal that is proportional to the concentration of the element in the sample. The signal is then processed by a computer to generate a mass spectrum, which shows the relative abundance of ions at different m/z ratios. The object of the tender process is described in more detail in the invitation to tender documents. |
