Waste water matrix CRMs have one or more definite characteristics and can be used as a measuring tool in the industry of analysis and measurement. Waste water matrix CRMs have some characteristics. First, the characteristic value of waste water matrix CRMs has the advantages of accuracy, uniformity and stability. Secondly, the quantity value of waste water matrix CRMs is transitive. Third, waste water matrix CRMs are physical objects. Fourth, each waste water matrix CRM is accompanied by a certificate to make it traceable.
The compositions in the waste water have the characteristic of complexity, and the pure standards can not meet the demands of the detection systems, so it is necessary to use the waste water matrix CRMs. The waste water matrix CRMs combine the target object with the matrix, so that it is consistent with the real tested samples, and can be used for the analysis of waste water quality. In addition, waste water matrix CRMs can effectively avoid the influence of matrix effect on the detection of substance composition, which is of great significance for the accurate control of waste water discharge quality. Common matrix standards include anionic surfactant, minerals, nitrite, oil, grease and others.
Analysis of heavy metal elements in waste water: Heavy metal elements, including zinc, lead, manganese, arsenic and others, are common substances in waste water. The excessive content of heavy metal elements has serious harm to the environment and organisms, so it is necessary to monitor the content of heavy metal in waste water. Waste water matrix CRMs can be used to analyze heavy metal elements by inductively coupled plasma spectrometry (ICP) method, which has the advantages of high sensitivity, strong selectivity and simple operation.
Analysis of pesticide residues in waste water: Monitoring pesticides in waste water, especially organophosphorus pesticides, is of great significance for environmental protection. Waste water matrix CRMs are essential to the establishment of testing methods. Using waste water matrix CRMs, pesticide residues in waste water can be quickly and accurately analyzed by gas chromatography, liquid chromatography, gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry and other analytical methods.
