Phenol Standards
Phenol standards are a subdivision of reference materials, which is a kind of physical standard. Phenol standards possess high purity and determined characteristic values. They are generally used in detection and analysis fields including calibration of instruments, evaluation of test methods, qualitative analysis, quantitative analysis and others. In addition, to meet the needs of different test methods, phenol standards can be pure substances or mixtures. Phenol is a highly toxic substance, which can enter human body through respiratory tract and cause poisoning.
In order to protect human life and health, it is necessary to use phenol standards for quantitative or qualitative analysis of phenol substance. Commonly used phenol standards include EPA phenols mixture, 2,3,5,6-tetrachlorophenol, 4-nitrophenol, 3-methylphenol, 4-chloro-3-methylphenol and others.
Application fields
Analyzing the phenol substances by ultraviolet and visible spectrophotometry: Using phenol standards, ultraviolet and visible spectrophotometry is an effective method for the quantitative analysis of phenol substances. During testing, phenol standards are often used as reference materials to establish the standard spectrum. The standard spectrum is an important basis for analyzing whether there is phenol substance in the tested sample and determining the content of phenol substance. In addition, this method has the advantages of simplicity and high efficiency.
Analyzing the phenol substances by high performance liquid chromatography: The phenol standards is necessary for the analysis of phenol substances in the samples by high performance liquid chromatography. In the process of the detection, the standard curves are drawn using the phenol standards. Then, according to the peak position and peak strength of the standard curves, the quantitative or qualitative analysis of phenol substances can be realized. For example, it has been reported that this method can be used to determine the phenol substances in biological products, which has the characteristics of high sensitivity, low detection limit and high selectivity.
The others: In addition to the above fields, phenol standards can also be used in a variety of detection fields, including gas chromatography, electrochemical oxidation, spectrophotometry and others. In these detection methods, the phenol standards are usually used as reference materials, so as to achieve the quantitative or qualitative detection of phenol substances.
