Description
UV-VIS & NIR Chemical Absorbance Systems:
The UV-VIS & NIR systems for chemical absorbance measurements have a range from 190 to 2300nm. Thy Spectrochemistry Systems include a miniature spectrometer, a light source, and sampling accessory such as cuvette holders, dip probes, & flow cells. The SpectraWiz Software has built in features for ChemWiz Concentration Analyzer with multivariate chemometric options and permits episodic capture for kinetics, time series analysis, & batch monitoring. It can easily convert to fluorescence or reflectance for multi applications and it is great for Teaching Labs, Research, Process Control & much more. it can be slso compared with our Fluorescence and Raman Systems.
Introduction into Near-Infrared Spectroscopy:
The near-infrared (NIR) region of the spectrum extends from the upper wavelength end of the visible region at about 770nm to about 2500nm (13,000 to 4,000cm-1). StellarNet RED-Wave-NIR and NIRX-SR model spectrometers extend to 2300nm capturing some of the most valuable absorption bands in the near infrared. These bands are overtones or combinations of fundamental stretching vibrational bands. The bonds involved are usually C-H, N-H, and O-H. Because the bands are overtones or combinations their molar absorptivities are low. Quantitative determination of species, such as water, proteins, low molecular weight hydrocarbons, and fats in products of the agriculture, food, petroleum and chemical industries. Both diffuse reflection and transmission measurements are used, although diffuse reflection is by far the most widely used. StellarNet offers TXF transmission fixtures and RFX reflection fixtures to facilitate these measurements.
A preconfigured Chemistry system for absorption analysis of liquid samples System consists of Black Comet-C 25um slit spectrometer, SL5-CUV, F1000-UVVIS-SR fiber optic cable, and SpectraWiz Spectroscopy Software.
