WATERS / MICROMASS GCT is a mass spectrometer that is used to analyze small molecules in a variety of solutions. The spectrometer is used to measure the masses and concentrations of compounds in liquid, gas, and solid solutions. The instrument can be used for routine sample analysis or quantitative analysis of complex samples, such as protein mixtures. The main component of the spectrometer is the detector system, which consists of a photomultiplier tube (PMT). This is used to detect particles and ions of different sizes and masses in the sample. The PMT is connected to an electron multiplier which sends an amplified signal to an amplifier and then a pre-amplifier before finally being sent to an analog-to-digital converter. The spectrometer also includes an ion source, which produces ions from the sample. This is usually achieved by either an electron beam or a thermo-ionization source. The ion source can be set to produce different ion energies, allowing for either comprehensive or selective detection. The electrospray ionization source uses high-velocity propelling droplets to create ions from the sample. This is a preferred method due to its high sensitivity and use of low energies. The sample is introduced at the top of the spectrometer and then sprayed with a stream of solution that passes through the detector array. WATERS GCT also features a range of additional components, such as a transmission system, an upper mass analyzer, and a lower mass analyzer. The transmission system helps to control the beam, convert the signal into signal transduction, and convert the electrochemical charge to mass signals. The upper and lower mass analyzers are used to analyze the particles and filter out noise. Overall, MICROMASS GCT is a highly efficient mass spectrometer for the analysis of small molecules in liquids, gases, and solids. Using its range of components, the spectrometer is able to detect a variety of substances and determine the mass and concentration of the sample. This makes the spectrometer useful for routine analysis and for complex quantification.
