Volatile aromatic hydrocarbons in soil (such as 12 typical pollutants including benzene, toluene, xylene, and chlorobenzene) primarily originate from human activities such as industrial emissions, petroleum spills, and the use of organic solvents. These compounds exhibit notable toxicity, persistenc...

The environmental industry is a rapidly growing field encompassing various aspects such as pollution control, resource recovery, and ecological conservation. Its market scale continues to expand, and technological innovation is advancing steadily. As a core instrument for heavy metal detection in ...

Steel corrosion is a primary factor affecting the durability of reinforced concrete structures. The presence of chloride ions in concrete is one of the main causes of steel corrosion, and chloride ion erosion is the most significant trigger for such corrosion. Concrete is primarily composed of ...

This experiment refers to "GB 31658.22-2022 National Food Safety Standard — Determination of β-Agonist Residues in Animal-Derived Foods by Liquid Chromatography-Tandem Mass Spectrometry" and utilizes the Wayeal LCMS-TQ9200 liquid chromatography-tandem mass spectrometry system to determine the ...

Parabens (p-hydroxybenzoates), as a class of highly effective and broad-spectrum preservatives, are widely used in the fields of food (such as soy sauce, vinegar, beverages, jam, etc.), cosmetics, and pharmaceuticals. Their antibacterial efficacy and safety directly impact product stability and ...

As a traditional Chinese medicinal herb, the medicinal value of artemisiae argyi folium primarily depends on the content of its volatile components. Eucalyptol and borneol are two key active substances among them. Eucalyptol exhibits pharmacological effects such as anti-inflammatory, cough ...

This application note introduces the determination of anion content in concentrated sulfuric acid, hydrochloric acid, and nitric acid using Wayeal ion chromatography. The traditional chemical volumetric method for determining impurity ions in concentrated acids is not only time-consuming and less ...

Acting as the "invisible guardian" of insulating glass, the desiccant's performance directly determines the risk of condensation and the service life of the glass unit. If its adsorption capacity fails to meet standards, it can lead to fogging or condensation between the glass panes, compromising ...

In an era of advancing environmental monitoring, food safety, and industrial process control, precise analysis of trace ions has become an industry-wide goal. Faced with sulfite ion detection under the HJ 84-2016 standard, are you looking for higher response and lower detection limits? Our newly ...
