Liquids NIR Analysis Made Easy!

The QuasIR 1000 is an FT-NIR spectrometer that brings together portability with unmatched spectroscopic performance.  It features a transmission chamber that can hold various sizes of cuvettes and glass vials up to 10mm.  Optional temperature control is offered; the sample compartment can be heated to 100C or cooled to 20C, for a wide range of applications. Liquid samples such as edible oils, lubricants, and fuels can be easily analyzed for quality control or adulteration.

The QuasIR 1000 ensures direct calibration transfer without the frustration of standardizing instruments or adjusting models to accommodate excessive instrument variability. The heart of the QuasIR 1000 is our PermAlign™ optics technology, an innovative optical design that maintains alignment and performance under conditions from the routine to the extreme. Our technology and design ensure unmatched consistency and direct methods transfer with no loss in performance so you can expand your QuasIR fleet with confidence. With PermAlign, you never need to make instrument adjustments and you can always have confidence in your results.

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.

Transmission Measurements for Liquids

The QuasIR 1000 is equipped with a temperature-controlled transmission cell for NIR analysis in liquids. The liquids samples can be heated or cooled to a consistent temperature to improve the accuracy and repeatability of the measurements.
