Near Infrared SpectroscopyNear-infrared (NIR) spectroscopy measures the interaction of near-infrared light with a sample, including transmission, reflectance and absorbance, facilitating the identification of analytes. Measurements can be conducted using a Fourier-transform near infrared (FT-NIR) spectrometer, while there are also UV-Vis- NIR spectrophotometers that measure a broader spectrum of wavelengths.

Gas analyzers can be used in supply chain processes and laboratory experiments with portable analyzers for monitoring CO<sub>2</sub> and O<sub>2</sub> levels as well as trace gases. Regular flow can be produced with gas control modules and flow meters.

Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Gas AnalysisGas analysis is used to measure the composition of gases in various environments, such as industrial processes, air quality monitoring, and environmental studies. Techniques like gas chromatography and mass spectrometry are commonly used.
