Near Infrared Analyzer Technical Data 23 Food and Beverages Sucrose, glucose, and fructose are three common sugars that are absorbed in different ways in the body. These sugars have slightly different effects. A key factor in their impact on our health is whether these sugars are naturally present in food or added during processing. The measurement of individual sugars and Brix (sugar content; °Bx, a scale for dissolved sugar content) is an important quality parameter in the food industry. These measurements can be performed using High-Performance Liquid Chromatography (HPLC), Ion Chromatography (IC), or Thin Layer Chromatography (TLC). However, these methods tend to be time-consuming and have high running costs. On the other hand, Near Infrared Spectroscopy (NIRS) can measure many sugars simultaneously within one minute without the need for chemicals or sample pretreatment.

【Near Infrared Analyzer Technical Data 24 Food and Beverages】 When considering root juice as a product, the sugar content in the product is a very important parameter because it is a sweet beverage. Among these, the contents of fructose, glucose, and sucrose are considered very important sugars for quality control. Traditionally, to measure these sugars in fruit juice through laboratory analysis, liquid chromatography is used along with refractive index measurement. When there are multiple analytical methods like this, each analysis requires time and expertise, as well as the need for different analytical instruments. Near Infrared Spectroscopy (NIRS) is an analytical technique that can simultaneously measure glucose, fructose, sucrose, and Brix in fruit juice in under one minute. Furthermore, it does not require chemical reagents, and no sample pretreatment is necessary.

[Near Infrared Analyzer Technical Data 25 Food and Beverages] Near Infrared Spectroscopy (NIRS) is an analytical method suitable for analyzing the density, water activity, and moisture content of green coffee beans. It does not require any chemicals or sample pretreatment, and NIRS can be easily used anywhere, whether near warehouses, roasters, or in analysis rooms.

Near Infrared Analyzer Technical Data 26 Agriculture Moisture in fertilizers is one of the most commonly measured parameters. Globally, regulations regarding different fertilizers vary, but local legal restrictions must not exceed the maximum moisture content. Various analytical techniques can be used for this moisture measurement. Following the gravimetric method, the Karl Fischer moisture meter is commonly used for accurate moisture measurement. Compared to these methods, near-infrared spectroscopy has unique advantages. It does not use chemical reagents and provides reliable results in just a few seconds. This application note introduces the analysis of moisture content in various fertilizer products using a near-infrared analyzer that allows for rapid and reagent-free analysis.

【Near Infrared Analyzer Technical Data 27 Food and Confectionery】 The production of food requires strict quality control to ensure its quality and protect consumers. Confectionery products, such as chocolate, are required to manage the final product to meet regulations and ensure consistent quality, which is especially important for luxury items. Near-infrared spectroscopy is a fast analytical method that requires no sample preparation and does not use chemicals, allowing for the determination of many important quality control parameters of chocolate bars. Near-infrared analyzers are easy to use and can be utilized in quality control laboratories as well as in environments close to the production site.

Near Infrared Analyzer Technical Data 28 Pharmaceuticals Cosmetics Cannabidiol (C-B-D) is a popular natural remedy used in many pharmaceuticals, foods, and cosmetics. CBD is just one of over 100 chemical compounds found in the cannabis plant. Unlike tetrahydrocannabinol (THC), CBD is non-psychoactive. This characteristic makes CBD an attractive option for those seeking relief from pain and other symptoms without the psychoactive effects associated with marijuana or resin concentrates. CBD oil is produced by extracting the compound from the plant and then diluting it with a carrier oil (such as coconut oil or hemp seed oil). The standard HPLC method takes a skilled analyst 45 minutes to perform the measurement. In contrast, the near-infrared analyzer (NIR) is a cost-effective and rapid analytical method for measuring cannabinoid content in oils.

【Near Infrared Analyzer Technical Data 29 Pharmaceuticals】 Cannabis has a long medical history as a recreational drug and as an analgesic and antispasmodic. The discovery of the major cannabinoids tetrahydrocannabinol, cannabidiol, and cannabigerol (THC, CBD, and CBG) has increased interest in its medical effects. THC is psychoactive and classified as an illegal drug in most countries, while CBD is legally accepted for medical purposes in many regions around the world. CBD is believed to alleviate anxiety and stress and promote better sleep. Due to the various effects and potential legal implications, determining the cannabinoid profile in cannabis has garnered significant interest. Generally, efficacy testing of cannabis is conducted using HPLC analysis. HPLC can detect low concentrations of cannabinoids but requires chemical reagents and is quite time-consuming. This technical document explains why near-infrared spectroscopy (NIR) is an excellent method for quantifying THC, CBD, and CBG in dried cannabis, as it provides results in less than one minute and does not require chemical reagents.

The OMNIS NIR Analyzer is a Swiss-made near-infrared spectrometer that performs quality control of liquid, viscous, and solid samples in just a few seconds.

The use of zero-calorie sweeteners as sugar substitutes in food products has dramatically increased over the past decade in soft drinks and snacks. Two examples of this are stevia, derived from the leaves of the Stevia rebaudiana plant, and sucralose, a chlorinated sucrose derivative. Both are much sweeter than sugar and are used at much lower concentrations in food. On the other hand, regulations regarding zero-calorie (non-nutritive) sweeteners have become stricter to ensure food safety. In response to these regulations, various sweeteners can be measured using high-performance liquid chromatography (HPLC), ion chromatography, and thin-layer chromatography; however, these measurement methods are time-consuming and have high running costs. By using near-infrared spectroscopy (NIRS), it is possible to simultaneously quantify several types of sweeteners in under one minute without the use of chemicals and without the need for sample pretreatment.

Near Infrared Analyzer Technical Data 31 Petroleum Related This technical document measures important quality parameters of diesel oil, including cetane index (ASTM D613), flash point (ASTM D56), CFPP: cold filter plug point (ASTM D6371), D95 (ISO 3405), and viscosity at 40 °C (ISO 3104).

2060 MARGA is a fully autonomous sampling and measurement system that can continuously measure water-soluble gases and aerosol components that directly affect air quality. The measurement results can be used in research to identify the structure of aerosols and to investigate how their concentration and composition change with diurnal and seasonal cycles.

In semiconductor manufacturing, standard cleaning processes are conducted in wet benches within clean rooms, where the environment is controlled to prevent further contamination. However, it is common for space to be very limited for installing analytical instruments in such environments. To monitor the main parameters of cleaning solutions simultaneously, more safely, efficiently, and quickly without using reagents, inline analysis using near-infrared spectroscopy (NIRS) is effective. Online analyzers, process analyzers, inline analyzers.
