Prediction of intact nectarine quality using a Vis/NIR portable spectrometer
A commercial visible-near infrared spectrometer was tested for intact nectarine quality prediction using partial least squares calibrations. Soluble solids content, firmness, fruit weight and colour index were analysed in each fruit. External validation carried out indicated good predictive performance, particularly for soluble solids content and fruit firmness. These parameters are of key ...

Measuring IR Light and Near-IR Light
Infrared (IR) light emits a broad range of non-visible wavelengths in the electromagnetic spectrum. Applications for infrared, including near-infrared, are defined by the respective IR bands during output. For example, LIDAR (Light Detection and Ranging) equipment uses 1,000 nm and 1,550 nm IR bands while surveying an area. In the military sector, 850 nm, 1,060 nm and 1,500 nm (and up) are used ...

Considerations when Purchasing a Near-Infrared Spectrometer
Understanding the Principles of NIR Spectroscopy Near-infrared (NIR) spectrometers measure the absorption or reflection of infrared light in the wavelength range 700 nm to 2500 nm (14,300 cm-1 to 4000 cm-1). For most applications, the range 1000 nm to 2500 nm (10,000 cm-1 to 4000 cm-1) is most useful; overtone and combination vibrations involving X-H bonds, (where is X is most often C, N, or O), ...

Determination of oil and grease in water with a mid-infrared spectrometer
The concentration of dispersed oil and grease (OG) is an important parameter for water quality and safety. OG in water can cause surface films and shoreline deposits leading to environmental degradation, and can induce human health risks when discharged in surface or ground waters. Additionally, OG may interfere with aerobic and anaerobic biological processes and lead to decreased wastewater ...
