Very high resolution Raman spectra can be obtained by adapting a Fourier Transform Infrared Spectrometer. The final element of the mass spectrometer is the detector. "Venera 15" analyzed and mapped the upper atmosphere with an infrared Fourier spectrometer. Tunable Laser Spectrometer (TLS). There are three principal advantages for an FT spectrometer compared to a scanning (dispersive) spectrometer. Lawrence began converting his old 37-inch cyclotron into a giant mass spectrometer. A secondary ion mass spectrometer can also be used. In these techniques, ions form in an ion source outside the mass spectrometer. It is a histogram usually acquired using an instrument called a mass spectrometer. The resulting ions are then analyzed by the mass spectrometer. The ICP-AES is composed of two parts&colon; the ICP and the optical spectrometer. It can be produced by a mass spectrometer instrument. Four spacewalks were conducted to repair the Alpha Magnetic Spectrometer. One of the main projects at ISTB 4 includes the OSIRIS-REx Thermal Emission Spectrometer (OTES). This will produce a set of peptides that can be analysed using a mass spectrometer.
