Processing & packaging contaminant standard is a class of chemicals with high purity. As a kind of reference material, processing & packaging contaminant standards have certain characteristics, which can be used in the calibration instruments, evaluation analytical methods, quantitative analysis, qualitative analysis and others. According to the demands, processing & packaging contaminant standards can be solid state and can also be liquid state. The commonly used processing & packaging contaminant standards include copper standard solution, cadmium standard solution, ditridecyl phthalate, mono-benzyl phthalate, acrylamide, bisphenol A, methyl phthalate, phthalic acid, isopentoic acid and others.
Analysis of heavy metal elements: Processing & packaging contaminant standards play important roles in the analysis of heavy metal elements including copper, septum, arsenic, mercury and others. For example, using processing & packaging contaminant standards as reference materials, heavy metal element contaminants in the process and packaging can be detected by inductively coupled plasma atomic emission spectrometry. Furthermore, this analysis method has the advantages of high selectivity, high sensitivity and fast analysis speed.
Analysis of plasticizers: Plasticizer is a very common processing & packaging contaminant, which will cause great harm to human health after entering foods, medicines or cosmetics. Therefore, it is very necessary to use processing & packaging contaminant standards to analyze this kind contaminant. For example, plasticizers in plastic packaging can be detected by high performance liquid chromatography (HPLC) after pretreatment. In the process of analysis and detection, processing & packaging contaminant standards are usually used to make standard curves. The type of plasticizer can be analyzed according to the peak position. The content of plasticizer can be analyzed according to the peak strength or peak area, so as to realize the quantitative detection of plasticizer. This method has high accuracy and good selectivity.
Others: In addition to the two fields mentioned above, processing & packaging contaminant standards can also be used to detect other contaminants, including alkanes, olefins, glycerides, tetrahydrosilicates and others.
