The compact heated liquid sampler is used with Galaxy Scientific’s QuasIR 2000 fiber based FT-NIR spectrometer to analyze liquid-based products’ samples. It features a temperature-controlled fiber-coupled main sample chamber along with a preheating chamber which is designed to hold multiple samples at a time. The compact heated liquid sampler has an easy to read 3.2” touch screen interface where the temperature values are displayed and set.

A calibration is shown for fresh poultry meat that analyzes protein, fat, and moisture content. The calibration model is then tested for accuracy by comparing the output of the near-infrared analysis to a known reference value for each sample.
Food and Drink International is a monthly magazine dedicated to global food and drink industry. The articles and features are informative, interesting, and cover all aspects of food.
In this exclusive feature, Galaxy CEO Richard Jackson, Ph.D., talks about the value NIR spectroscopy plays in the food industry.
This flyer lists the parameters measured using FT-NIR technology for multiple food applications such as snack food, dairy, edible oils, meat, and more. Multiple parameters’ measurements are done simultaneously and in less than 30 seconds.
Galaxy Scientific Inc. announces their latest product in their line of portable spectroscopy systems. Galaxy Scientific’s Fiber Optic Multiplexer allows a single spectrometer to automatically switch between up to ten different sampling devices enabling near-infrared measurements from multiple sampling points or multiple product streams.
The Multiplexer switches the input and output fibers from the spectrometer using a rotary steering mechanism. It is designed to accept standard SMA905 low-OH optical fiber inputs and is designed to switch 600um solid core fiber. Smaller core fiber or larger core fiber bundles are also compatible. The multiplexer is factory configurable at the time of order to have any number of channels between 2 and 10 and more channels can be added after purchase. The compact and rugged design allows the unit to be placed close to the sample points and distant from the spectrometer, reducing the cost of long fiber optic runs while still protecting the sensitive instrumentation.
Product features include:
• Factory configurable from 2 to 10 channels.; more channels can be added
• Available in single or dual configuration for switching a single fiber or dual fiber (input/output) setup
• 24V / 3A DC input with locking power connector
• USB (virtual serial port), RS-422/RS-485 interface with simple ASCII command set
• LED channel indicator
• High precision microstepping motors with advanced motion control driver
• Accepts SMA905 fiber optic connections, compatible with most commercial near-infrared probes and spectrometers
• Compatible with Spectral Sage, Symbion, and other process control software packages
Galaxy Scientific’s Multiplexer can be coupled with either the QuasIR 2000 fiber optic or QuasIR 2000E emission FT-NIR systems to provide a cost-effective solution to measurement needs at multiple sample points. The multiplexer is also compatible with other major NIR spectrometers.
Galaxy Scientific, a manufacturer of FT-NIR instrumentation for industrial use, is pleased to offer a Chart of Near-Infrared Absorption Bands in printed poster or PDF format.
This chart shows the wavenumber and wavelength ranges corresponding to common NIR absorbance peaks used in optical spectroscopy. The chart covers the optical range of 4000 cm-1 to 14000 cm-1 (or 2500 nm to 700 nm) and shows the combination bands as well as first, second, and third overtones for common functional groups. The functional groups covered include the following: CH, CH2, CH3, CHO, NH2, OH, ArOh, ArCH, CONH2, and H2O. Use these common functional groups to look up where to expect near-infrared absorptions in edible oils, polymers, sugars, and other organic materials.
You can download a free PDF of this chart here.

This lightweight power pack is selected to work with Galaxy Scientific’s QuasIR line of FT-NIR spectrometers. It is mainly used in field applications where local mains power is not available and offers a lifetime of 5 to 7 hours depending on the spectrometer’s configuration.
Galaxy Scientific’s App Note: Detecting Counterfeit Drugs Using FT-NIR
A suitable technology is needed to quickly, easily, and inexpensively screen medical drugs to detect fake products and poor quality ingredients. Traditional wet chemical or chromatographic methods cannot be used as fast screening tools as they are time-consuming and require expertise in sample preparation and handling. However, near-infrared (NIR) spectroscopy is rapid, non-destructive, and can be used to differentiate and quantify organic compounds. With no complex sample preparation, NIR spectroscopy can be extremely inexpensive per sample. NIR spectroscopy can also differentiate between generic formulations that are sold as brand name drugs. The most impressive example of using NIR spectroscopy as a counterfeit drug screening tool comes from the People’s Republic of China. Researchers at China’s National Institutes for Food and Drug Control (NIFDC) have equipped 200 vans with FT-NIR spectrometers turning them into mobile labs for counterfeit drug testing.
FT-NIR spectroscopy to Analyse Rice… Since the 1950s, scientists have been searching for parameters that can define the cooking quality and processing characteristics of rice, as well as its chemical and physical testing methods. For example, amylose content and alkali diffusion values are widely used worldwide in rice breeding. Amylose content is related to water absorption, swelling, viscosity, and glossiness of rice. The alkali diffusion value is related to the gelatinization temperature of milled rice starch granules. The viscosity of rice paste during heating and cooling is often measured as an indicator of the milling properties of rice flour. Although the content of protein is not often used in rice breeding, it is nevertheless an important factor because it directly affects cooking time, texture, and nutritional value. The fat content is also an important nutrient of rice; it has a significant influence on the flavor, appearance, and quality. Additionally, the fat content in rice decreases with the extent of processing.

Fats and oils are recognized as essential nutrients in human diets and are presented in varying amounts in many foods. They not only provide the human body with a concentrated source of energy but also supply essential fatty acids that are precursors for important hormones. The quality of edible fats and oils are assessed through parameters such as iodine value (IV), trans content, peroxide value (PV), anisidine value (AV), saponification number (SN), free fatty acids (FFA), and solid fat content (SFC). The traditional chemical and chromatographic methods used to analyze edible fats and oils are labor-intensive, require the use of solvents and reagents, and are extremely time-consuming.
FT-NIR spectroscopic analysis of fats and oils is fast, requires no sample preparation, and can analyze multiple parameters with a single measurement. An infrared spectrum of an oil contains a wealth of information that can be used to determine important factors.
