UV-Vis Spectrophotometer in Diverse Applications
Key words: UV-visible spectrophotometer; US instrumentation; UV-1100; UV-1800
The UV-Vis spectrophotometer is a fundamental analytical tool used across various industries, including pharmaceuticals, environmental monitoring, and food safety. It plays a crucial role in quality control and analysis due to its ability to measure the absorption of ultraviolet and visible light by substances.
In the pharmaceutical sector, the UV-Vis spectrophotometer is essential for drug testing and quality assurance. Many countries' pharmacopoeias require the use of this instrument for the quality control of drugs, especially those with a spectral bandwidth less than 2 nm. Commonly tested drugs include vitamins, antibiotics, analgesics, antihypertensives, sedatives, cough suppressants, eye drops, sulfonamides, diuretics, gynecological drugs, and anti-cancer agents. This makes it an indispensable part of the pharmaceutical and drug testing industries.
In the petroleum industry, UV-Vis spectrophotometers are widely used for oil analysis. They help determine the concentration of hydrocarbons in wastewater, surface water, and refinery effluents. The characteristic absorption peaks at 225 nm and 254 nm are key for identifying and quantifying petroleum components. These instruments also detect aromatic impurities around 320 nm, ensuring that oil quality meets strict environmental standards.
Environmental monitoring benefits greatly from UV-Vis spectrophotometry as well. It is used to detect toxic substances such as phenols, anilines, nitrophenols, surfactants, and heavy metals in water and soil. Many national water standards require the use of these devices for accurate detection of harmful compounds like ammonia nitrogen, total phenol, and nitrophenols.
In the feed industry, UV-Vis spectrophotometers are used to analyze vitamins, amino acids, and trace elements in raw materials and additives. They also help detect pesticide residues and other harmful substances in animal feed, ensuring the safety of livestock and poultry products.
Pesticide residue analysis is another critical application. These instruments identify not only the original pesticides but also their metabolites and degradation products, which may be more toxic than the parent compound. For example, DDT metabolites like DDE and BHC metabolites can cause severe health issues. Monitoring these residues is vital for public health and environmental protection.
In aquatic product quality control, UV-Vis spectrophotometers are used to monitor pollutants such as benzene, trihalomethanes, PCBs, mercury, and fluorine in seawater and freshwater. These instruments help ensure the safety of fish, shellfish, and shrimp, which can accumulate toxins through the food chain. The bioaccumulation factor of certain contaminants can reach over 10^4 in fish, making UV-Vis spectrophotometry a key tool in fisheries management.
Overall, the UV-Vis spectrophotometer is a versatile and essential analytical instrument that supports numerous industries. Its applications range from drug development to environmental protection, food safety, and beyond. With ongoing advancements in technology, its role will continue to expand, making it an irreplaceable tool in scientific research and industrial quality control.

Load Cell
According to the conversion method, Load Cell is divided into 8 categories, such as photoelectric type, hydraulic type, electromagnetic force type, capacitive type, magnetic pole change type, vibration type, gyro ceremony, and resistance strain type. It is a method that converts quality signals into measurable electrical signals The output device mainly has several styles such as S type, cantilever type, spoke type, plate ring type, bellows type, bridge type, and cylinder type.
The sensor has the following advantages:
(1) High impedance, low power, only requires very low input energy.
(2) Larger variation can be obtained, thus having higher signal-to-noise ratio and system stability.
(3) The dynamic response is fast, the working frequency can reach several megahertz, dense b contact measurement, the measured object can be a conductor or a semiconductor.
(4) The structure is simple. Strong adaptability, can work in harsh environments such as high and low temperature, strong radiation, etc., and has a wide range of applications.
