Near infrared spectroscopy has been widely used in the chemicals and polymers industries for years. This is because it is a rapid technique that eliminates sample preparation and costly consumables. FT-NIR analysis is non-destructive, capable of simultaneous analysis of multiple components, and can be used for online monitoring. With flexible sampling mechanisms, NIR can analyze solids, liquids, and gasses.
Compared to traditional methods such as wet chemistry, HPLC and gas chromatography, NIR spectroscopy provides considerable advantages in process and quality control (QA/QC) applications such as:
NIR eliminates the need for consumables such as solvents, columns, and reagents.
NIR provides real time analysis – generally less than 30 seconds’ measurement time; it also eliminates sample preparation time.
Portable NIR spectrometers can be used in the field as well as in the lab and can measure multiple components per analysis.
Our NIR spectrometers are user-friendly, providing point-of-need analysis.
NIR means the elimination of many sources of systematic error, particularly during sample and test preparation
Some of the main NIR applications in the chemicals and polymers industry are incoming quality control, like hydroxyl number analysis of polyols. Polymerization process monitoring, such as inline, real-time hydroxyl number and isocyanate number monitoring during a polyurethane reaction. Finished product quality assurance and sorting and recycling applications such as plastic identification and waste carpet sorting.
Galaxy Scientific offers off-line / in-line / at-line FT-NIR solutions for analysis of chemicals and polymers. Our QuasIR™ 2000 can couple with transmission or diffuse reflectance probes for in-line / off-line / at-line measurements. The QuasIR™ 4000 is equipped with both integrating sphere and sample compartment, which can be utilized for off-line solids and liquids measurements.
