Near Infrared Analysis Chemometrics Instrumentation Custom Software Custom Hardware
PRODUCT DESCRIPTION - QUANTITATIVE ANALYSIS SOFTWARE
The Near Infrared Research Corporation provides the only commercially available software package combining MLR calibration mathematics with extensive automatic wavelength selection capability to calibrate spectrometers for quantitative chemical analysis. Simplicity of operation is provided through the incorporation of unique, cutting-edge algorithms to enable the computer to automatically search for and select the optimum wavelengths to use for the analysis, and a program to do the analysis of unknowns. Calibration models can be concatenated to allow analysis of multiple constituents in each sample.
The two search algorithms enhance flexibility by allowing the user to control the nature and extent of the search. One algorithm is a uniquely efficient algorithm to control the search pattern; this is useful for situations where many wavelengths are to be included, the other provides flexible searches under user control up to all-possible-combinations searching.
A Prediction program is included that allows analysis of future unknown samples based on their measured spectra and the results from the calibration algorithms.
