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. NIR 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.

Our QuasIR™ 2000 is a portable Fiber Optic FT-NIR Near Infrared Spectrometer that can be equipped with a wide range of reflection, transmission or transflectance probes depending on the application. It was designed from the ground up to offer the industry a new kind of NIR
analysis solution – a solution that brings together the portability required to move NIR analysis closer to point-of-need, combined with unmatched spectroscopic performance for the fastest and most accurate results.
The NF 2000 is a portable Fiber Optic FT-NIR Near Infrared Spectrometer that is equipped with a reflection probe, and a built-in probe holder and background. Transmission or transflection probes can also be used with the instrument.
The QuasIR™ 2000E is designed for continuous measurement of the chemical composition of material transported on a conveyor belt, through a pipe, or in a chute. It features- unique external projection optics using high powered tungsten lamps to illuminate the sample from as far as 24 inches away and collect the scattered reflection off the sample through a fiber optic cable.
Our QuasIR™ 3000 FT-NIR spectrometer is equipped with an integrating sphere for reflection measurements of solids as well as transflectance measurements of opaque liquids and pastes. The instrument has a wide range of applications, especially in the food and agriculture sectors.
Our QuasIR™ 4000 FT-NIR spectrometer is our most popular instrument. It combines the capabilities of our the QuasIR™ 1000 and the QuasIR™ 3000 making it very versatile and unique. It can be used to analyze liquids, solids and pastes since it is equipped with both an integrating sphere and transmission chamber.
