Perkin Elmer US LLC AVI Calibration Methane Cell
Supplier: Perkin Elmer US LLC L1250462

Discrepancies can exist between FT-IR spectrometers. An instrument's wavenumber and lineshape values can be adversely affected as a result of changing sampling accessories and components. Absolute Virtual Instrument (AVI) is a Spectrum software function that ensures wavelength and lineshape standardization for all FT-IR istruments. When AVI is turned on, the spectrometer's Spectrum software compares the spectrometer's wavelength and lineshape measurements against methane cell's measurements and updates the instrument's AVI profile, when necessary.
