Most organic fluorine compounds are assumed to be the total of all adsorbable organic fluorine (AOF) compounds in water. The measurement of AOF is simpler and faster than target analytical methods, and it is more sensitive than total fluorine (TF) measurements (which include all organic and inorganic F). Measuring AOF in water samples as an initial screening process allows for the screening of the actual amounts of organic fluorine compounds present. Following this, if indicated by high AOF concentrations, it can serve as a criterion for conducting target analysis of individual PFAS.

Lithium-ion (Li-ion) batteries are one of the most researched energy storage devices due to their relatively high energy levels and excellent power performance. During charging, lithium ions are moved from the positive electrode to the negative electrode through the electrolyte. During discharging, lithium ions move in the opposite direction, from the negative electrode to the positive electrode. At the electrode surface, the diffusion of Li-ions into the bulk occurs. Here, the performance of Li-ion batteries largely depends on the diffusion coefficient of the active materials present in the electrodes. Therefore, knowing the chemical diffusion coefficient of the electrode materials is very important. Additionally, understanding the thermodynamic properties of the electrode materials provides a more detailed insight into their electrochemical behavior.

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 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.

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.

The method for refining alumina from bauxite is called the "Bayer process." Since it is more cost-effective and energy-efficient to refine aluminum directly from alumina, this method involves dissolving crushed bauxite in high-temperature calcium oxide (hereafter referred to as CaO) and sodium hydroxide (hereafter referred to as NaOH) to create an "aluminate solution." Additionally, CaO is causticized and removed by the carbonate generated from the decomposition of organic matter in the alkaline solution and the absorption of CO2 from the atmosphere. Impurities are removed at various stages of the process. The aluminate solution is filtered, and the alumina crystals that remain as solids are returned to the dissolution process for reuse. Before utilizing the filtered aluminate solution, it is necessary to measure the concentrations of hydroxides (caustic), carbonates, and alumina. This technical document focuses on online monitoring of the concentrations of hydroxides, carbonates, and alumina in the aluminate solution using the temperature titration method of the Metrohm Process Analytics 2060TI Process Analyzer or 2035 Process Analyzer.

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.

Pure nickel is a silvery-white metal that is very hard, corrosion-resistant, and ductile. Due to these remarkable properties, nickel is used in many applications, primarily in coatings and surface engineering. Electroless nickel plating is a self-catalyzing chemical technique for depositing a layer of nickel-phosphorus alloy onto the surface of a workpiece. This method relies on the concentration of a reducing agent (sodium hypophosphite) that reacts with metal ions for plating. However, since the lifespan of the chemicals in the plating bath is limited, automatically monitoring the consumption of these chemicals becomes an important process control requirement. Prolonged use of the plating bath leads to an overload of reaction products in the electrolyte, adversely affecting the properties of the workpiece's surface and the layer. This process application note proposes a method for regularly monitoring various active bath components in the electroless nickel plating bath to ensure the uniform deposition of nickel-phosphorus alloy layers.
