Digitization in the field of NIR spectroscopy (smart sensors)

Digitalization is advancing, also in NIR spectroscopy, which enables trainable miniature smart sensors e.g. for analyses in the food&feed, chemical and pharmaceutical sectors.

The calibration is the core of a NIR spectroscopy sensor, it enables the numerous applications and should therefore not be the weakest link in the measurement chain.

The development of calibrations that turn NIR spectrometers into smart sensors is done manually by experts (NIR specialist, chemometrician, data scientist) with so-called chemometrics software.

This is very time-consuming (time to market) and the result is person-dependent and thus suboptimal, because each expert has his own preferred way of proceeding. In addition, the calibrations have to be maintained, as new data has been collected in the meantime, which can be used to extend and improve the calibrations.

This is where our automated service comes in, combining the knowledge and good practices of NIR spectroscopy and chemometrics collected in one software and using machine learning to generate optimal calibrations.

Based on this, we have developed a complete technology platform (Time to Market) that covers the entire process from sending NIR + Lab data, to NIR Calibration as a Service, from online purchase of calibrations, to NIR Predictor software that directly evaluates newly measured NIR data locally and generates result reports.

Besides the free desktop version with user interface, the NIR Predictor can also be integrated (OEM). This can be integrated in parallel as a complement to your current Predictor, allowing the user to choose how they want to calibrate. And give them the advantage in NIR feasibility studies and NIR spectrometer evaluations to quickly provide the customer with a solid and accurate calibration that will make their NIR system deliver better results.

Advantages for your NIR users (internal or external)
  • no initial costs (no chemometrics software license required),
  • calculable operating costs (fixed amount instead of time and hourly rate) (calibration development, calibration maintenance)
  • easy to use (no chemometrics and software training),
  • quicker to use (no calibration development work) and
  • better calibrations (precision, accuracy, robustness, …)

Our chargeable service is based on the calibration development and the annual calibration use. Calibration development and calibration use can also be carried out separately (manufacturer / user).

For you as a spectrometer manufacturer, this means that you can deliver your system pre-calibrated for certain applications without incurring software license costs. And without your application specialists having to provide additional calibration services.

The unique advantages of our calibration service together with the free NIR Predictor are:
  • no software license costs (chemometrics software, predictor software, OEM integration)
  • no chemometrics know-how necessary
  • no time needed to develop optimal NIR calibrations.

How to start building a NIR Calibration (a NIR prediction model)?

With at least 60-100 different NIR measured samples with different Lab values
we can develop a quantitative NIR Calibration for you!

You don’t need to operate with expensive Chemometric Software.
Don’t worry, prices are inexpensive for that and all software you need is included.
Price comparison

The free NIR-Predictor software allows to combine your measured NIR-Spectra with the Lab values of the samples. And checks your data and creates a Calibration Request file for you. NIR-Predictor Info

With that you can order your individual customized calibration, by sending the Calibration Request file to info@CalibrationModel.com.

After processing you will get an Email with a link to access your customize calibrations in our WebShop where you can purchase and download the calibration file immediately
for use in the included free NIR-Predictor software to get results predicted out of spectra files. NIR-Predictor software

For your Calibration start-up cycle we provide low-price short living calibrations, that work for e.g. 3 or 6 months. Pricing

During that Calibration usage time you have measured more samples and collected more NIR and Lab data to build a bigger and better calibration.
E.g. you got samples that extend the range of the constituents.
Or you have collected the Lab values of additional constituents.

Yes out of an measured NIR-Spectrum you can get multiple constituents predicted at the same time (a quantitative calibration per constituent is needed).

And NIR-Predictor does handle this with ease and creates NIR Prediction Reports (printable, archive-able) of all the calibrations you have in folder named with e.g. “MyFruitApplication”.

And having multiple such applications, in NIR-Predictor you can easily switch between the applications for analyzing new NIR spectra files.

The NIR spectra files are found from the stored or exported folder from your NIR-Spectrometer software. supported File Formats
