Measurement Guide
For a detailed explanation on how to measure textile samples watch our tutorial (PAL One).
1. Prepare your spectrometer
Keep the scan window clean and dry to ensure accurate measurements. If necessary, use soft gauze and alcohol such as ethanol or isopropanol for cleaning.
Switch on the spectrometer.
2. Connect and calibrate your spectrometer
Open the Spectroscopy App (PAL One) or the Guide App (PAL Two) to connect your spectrometer.
Then perform a calibration. You must perform an open port scan and a reference scan. Follow the instructions in the app to do this.
3. Prepare your sample
Make sure that your sample is dry and clean before you start the measurement. When scanning wet samples, please use a dry cloth to wipe off any water drops on the material as water will affect the result.
Select the application that corresponds to your sample type in the respective app.
4. Perform a measurement
Maintain direct contact between the sample and the spectrometer’s scan window. Start the scanning process by operating the spectrometer directly using the button or via the app.
To obtain a more representative result for textile samples with mixed fibers, take measurements at several points and stretch the textile across the scan window.
Between measurements, regularly check the scan window for dirt, particles, or other contaminants.
Additional information on measurement deviations
Some textiles have layered structures, with different materials on the outside compared to the inside (e.g., jackets, blazers, hoods). Since NIR spectroscopy primarily analyzes surfaces, results will vary depending on which side is measured.
Do not measure labels or printed areas, they are usually made of a different material than the textile sample itself.
In case of single fibers, make sure to measure them in bulk by completely covering the scan window.
