Reliable On-line NIR analysis for improved process quality and consistency!

Galaxy Scientific’s 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.  Our unique external projection optics use high powered tungsten lamps to illuminate the sample from as far as 30 inches away and collect the scattered reflection off the sample through a fiber optic cable. The analysis spot size can be set as small as 3″ or as large as 6″ in diameter and can be custom tailored to applications needs.

The QuasIR™ 2000E uses FT-NIR technology to deliver the most repeatable and accurate real-time results. Our rugged PermAlign™ interferometer optics deliver results in environments where other interferometers fail. Full compatibility with popular process control and chemometric software means the QuasIR™ 2000E can be integrated into almost any process environment.

Key applications include mining, food production, recycling, web processing, in-process quality control, and much more. Gain real-time insight into mixing, drying, curing, baking, polymerization, and in-process concentrations. Monitor processes for critical quality parameters.

Direct calibration transfer

Historically, transferring NIR calibrations from one instrument to another has been a challenging task. One of the greatest advantages of FT-NIR technology is direct calibration transfer. NIR calibration can easily be transferred from one FT-NIR instrument to another even if it is not the same model or made by the same manufacturer.

Rugged, compact and portable design

Galaxy Scientific FT-NIR spectrometers combine portability and performance to get the near infrared results you need, where and when you need them. Our robust and compact design is dust proof and splash proof and can be taken outside the lab to the point-of-need. Our near-infrared spectrometers are lightweight with a small footprint and quickly attach to a laptop or tablet computer, can operate from a variety of power sources, and have a rugged design that ensures they can be moved without damage.

High-Performance Measurements

Galaxy Scientific’s high-performance FT-NIR technology offers significant advantages such as high spectral resolution, best-in-class signal-to-noise ratio, inherently stable wavelength accuracy, and full spectral range. All models utilize Galaxy’s PermAlign™ Fourier Transform Technology, taking near-infrared instrumentation to the next level by offering incredibly high-performance measurements in a small, portable design. Benefits include permanent interferometer alignment, small & lightweight design, and robust field operation

Depot Service & Low cost of ownership

Galaxy Scientific products were designed to be compact, precise, and economical. Our QuasIR™ Series of near infrared spectrometers use a temperature stabilized solid-state laser that offers a compact configuration, excellent wavelength stability, and a typical lifetime of over 10 years. In addition, our instruments use a special compact lamp that offers a typical lifetime of 20,000 hours and an inexpensive replacement cost. Galaxy Scientific’s QuasIR™ has a wear-free interferometer drive that comes with a 10-year warranty, and user replaceable desiccant.

This compact design allows us to offer “depot service” meaning our products can be easily shipped via standard shipping methods, without the need for a freight shipment. A product can be overnighted to us, evaluated and repaired (if needed) upon receipt and then overnighted back to our customer. This is much cheaper and faster than having to send a specialist to the customer site…

Simple Installation by User

Galaxy Scientific products are designed to be easily installed by the end user and without the need for an expensive on-site product start-up by our experts.

Large area standoff diffuse reflectance measurement

The QuasIR 2000E is equipped with a heavy-duty industrial measuring head for continuous measurements and monitoring of material moving over conveyors, pipelines, webs, hoppers, and chutes.  Measuring area could be set to anywhere between 3 to 6 inches diameter for improved reproducibility and accuracy.
