NIR Spectrometer Analyzers for Quality Inspections

The ChemWiz-ADK^TM works by measuring the reflected near-infrared light waves from your sample.  Each system must be calibrated for a specific type of sample and StellarNet provides Starter Calibration Packages for a variety of sample types.  Simply place your sample into a measurement dish and place on the sample fixture.  Composition results are display instantaneously!

1. Power-up unit via the main power control button
2. Turn on integrated Andriod Tablet
3. Launch the ChemWiz-ADK PRO App
4. Set the provided calibration reference on fixture and click the “take reference”
5. Set your sample on the fixture and click “Analyze”
6. Your results will appear nearly instantaneously on screen

Great question!  Most of our analyzers can predict within 1% of any major component from our own sample sets here at StellarNet.  And in some cases we can do even better than that.

However, the Analyzers are based on NIR (near-infrared) reflectance technology and the system’s accuracy for you is based on our starter calibration packages and comparability with your own samples.

Calibration Model Refinement and Customization is a fairly quick process where you are initially paired with a StellarNet calibration engineer who assists you throughout.  We have several options available for customers based on their technical skills or interest level.  30-50 samples must be measured and sent to a local laboratory.  Samples should have a wide variety of composition and encompass all possible samples that you might encounter. You can either send the samples to our Headquarters in Tampa, Florida or we can remote into your ChemWiz-ADK analyzer and guide you through placing samples on the fixture and performing the measurements.  Our calibration engineer will verify that all the spectral data is taken properly and will then export the data for model building.  Once lab results are back, we will input collected spectra and lab results into our chemometrics engine and generate a refined and/or customized calibration model for you.  Simply select this new model in the ChemWiz-ADK PRO App and begin using your new customized model.

StellarNet, Inc. has been the low cost leader in research grade spectrometer instrumentation for the past 25 years! We are a primary manufacturer of spectrometer hardware and use our own spectral engines in our analyzers. Other companies have to purchase OEM modules from companies like ours driving up their final system costs. 

The ChemWiz-ADK^M Analyzers use near-infrared diode array technology with a 512 pixel detector.  Most competitive diode array analyzers use only 256 pixels.  This means our systems achieve 2x the spectral resolution!

The ChemWiz-ADK-Case Analyzers use our patented 3D optical collection system that removes the requirement to spin samples.  This means you can get a multi-angle reflectance measurement of your sample without needing to move or spin your sample.  This drastically reduces measurement speed and system robustness.
