Custom-built FT-IR for Online Measurement of a Commercial, Protein Hydrolysis Process
Low-cost resonant cavity Raman gas probe for multi-gas detection
Raman based gas sensing can be attractive in several industrial applications, due to its multi-gas sensing capabilities and its ability to detect O2 and N2. In this article, we have built a Raman gas probe, based on low-cost components, which has shown an estimated detection limit of 0.5 % for 30 se...

Low Cost “Laserless” FTIR Spectrometer with Resolution Better Than 0.5 cm-1
Abstract: We have designed a FTIR instrument where the traditional He-Ne reference laser is replaced by a low-cost linear encoder. We achieve an RMS sampling error of less than 50nm by oversampling both the interferogram and the encoder signal and then resampling the interferogram using a correction...
Near-Infrared (NIR) Interactance System for Non-Contact Monitoring of the Temperature Profile of Baked Liver Pâté
This article investigates the possibility of using non-contact interactance as a method for profiling the temperature in a processed meat product (liver pâté) as it comes out of the oven. The application was defined by an industrial partner, Nortura SA, Tønsberg, Norway, where more control of the co...
On-line determination and control of fat content in batches of beef trimmings by NIR imaging spectroscopy
An NIR imaging scanner was calibrated for on-line determination of the fat content of beef trimmings. A good calibration model was obtained for fat in intact beef (R = 0.98, RMSECV = 3.0%). The developed model could be used on single pixels to get an image of the fat distribution, or on the average ...
