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. product_group: Calibration Reference Materials,\u003cbr\u003e\ntechnology_type: IR\u003c\/p\u003e","brand":"Perkin Elmer","offers":[{"title":"Default Title","offer_id":46769128177833,"sku":"L1250462","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/perkin-elmer-l1250462","provider":"Iright","version":"1.0","type":"link"}
