Chemicals reagents are commonly referred to simply as reagents. Chemicals reagents are a large class of pure chemical substances with various standards of purity and can be used for the synthesis, separation, qualitative and quantitative analysis of substances. They can be said to be the eyes of chemical workers. Chemical reagents are indispensable in all kinds of industries, such as industry, agriculture, medical and health, life sciences, inspection and quarantine, environmental protection, energy development, national defense, military industry and scientific research.

Techniques for chemical reagent testing
Mass Spectrometer
A mass spectrometer is an instrument used to analyze chemical substances by decomposing, ionizing, and separating the chemical components of a sample. It detects the compounds and elements present in the sample. Mass spectrometers are widely applied in various fields, such as life sciences, healthcare, and environmental monitoring. In the chemical industry, they are commonly used to identify and determine the composition and mass of organic and inorganic substances.
Infrared Spectrometer
An infrared spectrometer is a device for detecting and analyzing chemical substances. It works by analyzing the infrared light emitted or absorbed by a sample to determine its molecular chemical structure and composition. Infrared spectrometers are extensively used in fields such as materials science, medicine, and the food industry. In the chemical industry, they are often employed to analyze the structure and composition of organic and inorganic compounds.
Gas Chromatograph
A gas chromatograph is an instrument for analyzing chemical components by separating substances into different fractions and detecting their behavior in the gas phase to derive chemical information. Gas chromatographs are widely used in fields such as biochemical analysis, materials testing, and environmental monitoring. In the chemical industry, they are commonly used to analyze the chemical composition of products in sectors like petroleum, chemicals, and food.
Flow Injection Analyzer
A flow injection analyzer is an instrument designed for biochemical analysis. It confirms and analyzes the composition of a sample by injecting it into a specific analytical system. Flow injection analyzers are widely utilized in areas such as pharmaceutical manufacturing, the food industry, and environmental monitoring. In the chemical industry, they are often used to analyze the chemical composition of products in industries like food, chemicals, and petroleum.

Microplastics Overestimated Due to Poor Quality Control in Reagents
Bai, Runhao, et al. Journal of Hazardous Materials 459 (2023): 132068.
Microplastics are ubiquitous in the environment, posing significant ecological risks and emerging as a critical environmental pollutant. However, when assessing microplastic contamination in environmental samples, insufficient quality control of reagents used in analytical processes can introduce microplastic contamination. This may lead to overestimation of microplastic abundance in the samples.
This study evaluated microplastic contamination in commonly used flotation and digestion reagents to identify errors stemming from microplastics within these reagents. The results revealed that the abundance of microplastics in the reagents ranged from 0.8 to 43.4 items per gram, with lower microplastic levels observed in flotation reagents compared to digestion reagents. The detected microplastics included particles, fibers, and fragments, mostly smaller than 100 µm. Polyethylene and polypropylene were identified as the most common polymer types.
To improve the applicability and readability of the results, microplastic abundances were normalized to the actual working concentrations of the solutions. The potential microplastic contamination in untreated flotation solutions ranged from 1.5 to 30.8 items per milliliter, while in digestion solutions it ranged from 0.1 to 2.3 items per milliliter.
This study highlights the critical need for implementing robust quality control measures, such as suction filtration, when assessing microplastics in environmental samples or conducting chemical and biological experiments involving microplastics. These steps are essential to ensure accurate and reliable results, minimizing the risk of overestimation due to reagent contamination.
