AVI Correction  

AVI correction can be selected in the Setup Instrument Advanced tab in Spectrum 

(Figure 18). 

AVI correction can only be performed if an AVI Calibration has been set up for the current 

configuration and resolution. Select 

AVI

 from the 

Adjustments Toolbox

, available from the 

Setup Instrument Advanced Tab. Follow the instructions on-screen. For further information, 

refer to the Spectrum on-screen Help file. 

NOTE:

 AVI correction uses a methane gas cell installed in the filter wheel.  

What is AVI correction? 

The objectives of Absolute Virtual Instrument (AVI) correction are: 

•

 

Consistent performance over time and between instruments 

•

 

Traceability for all measurements. 

Although FT-IR spectrometers use a reference laser, the wavenumber calibration and 

lineshape are affected by differences in beam divergence and uniformity. This is true for all 

FT-IR spectrometers. Differences can occur between instruments, when using different 

sampling accessories and when components are changed. AVI allows calibration and 

lineshape to be maintained. 

The Absolute Virtual Instrument is an instrument with theoretical performance, such that the 

result of measuring a known sample on such an instrument can be predicted. So, if we 

measure with a real instrument and calculate the software transform to match the theoretical 

result, we can apply this transform to future measurements. 

The Absolute Virtual Instrument is defined by wavenumber calibration, instrument lineshape 

and ordinate accuracy. 

What does AVI correction do? 

When 

AVI

 is switched on, the software measures the current instrument profile relative to an 

absolute standard (the methane cell) and an ideal lineshape function, and applies a 

correction (Figure 21). If you have an automated, internal filter wheel, this can provide 

correction for any sampling configuration.
