Accessory Pack for Spectroscopy

If you have very noisy data, Orthogonal Signal Correction (OSC) can help you generating improved models. OSC also helps you obtain better models by using fewer Principal Components when you have large X-data sets.

Orthogonal Signal Correction can generate improved models particularly with large amounts of variance not related to the property of interest. Models will have fewer components for easy interpretation.

Calibration transfer functions:

Enable fewer measurements and calibrations.
Reduce time when generating models at new instruments.
Reduce the amount of samples needed when making calibrations.
Get more robust models.
Increase the longevity of models since you can easily add new samples that cover a new range.
Use one expensive instrument; generate a model that can be used together with less expensive instruments.

Deresolve:

On occasion, one may wish to standardize a lower resolution instrument to a higher resolution instrument. In such an instance, it may be more effective to mathematically lower the resolution of the higher resolution instrument prior to forming the transfer model. The Deresolv Smoothing Function can be used to change the apparent resolution of an instrument and may also generate some beneficial noise reduction. This function works by FFTing the spectra, convolving it with an impulse of specified width, then back FFTing the result.
