Aldehydes and aldehyde derivatives can be used as certified reference materials for chromatography when they meet specific requirements. Aldehydes and aldehyde derivatives certified reference material is a branch of reference material, and the distinctive feature is that each aldehydes and aldehyde derivatives certified reference material is attached with a certificate. In addition, aldehydes and aldehyde derivatives certified reference materials are generally prepared in batches, and their characteristic values are determined by measurement of samples representing the whole batch. In order to meet the requirements of different chromatographic analysis, the aldehydes and aldehyde derivatives certified reference materials can be either pure or mixed substances. Commonly used aldehydes and aldehyde derivatives certified reference materials include acetone-2,4-DNPH, formaldehyde-2,4-DNPH, acetaldehyde and others.
Application fields
Detection of aldehydes and aldehyde derivatives in textiles: In order to protect the health and safety of consumers, many governments and organizations have strictly limited the content of aldehydes and aldehyde derivatives in textiles. Using chromatographic method to analyze the type and content of aldehydes and aldehyde derivatives has the advantages of high sensitivity, high selectivity and high accuracy, so it has been widely used. Furthermore, aldehydes and aldehyde derivatives certified reference materials are essential for chromatographic analysis and detection. For example, using formaldehyde-DNPH certified reference material can achieve accurate detection of formaldehyde content in textiles.
Detection of aldehydes and aldehyde derivatives in air: Aldehydes and aldehyde derivatives are important air pollutants, which can damage the environment and harm the health of organisms. Therefore, it is urgent to test it with aldehydes and aldehyde derivatives certified reference materials. After collecting aldehydes and aldehyde derivatives in the air, they can be analyzed and determined by gas chromatography or liquid chromatography. In both test methods, aldehydes and aldehyde derivatives certified reference materials are demanded. The content and types of aldehydes and aldehyde derivatives in the air can be determined by comparing with the peak position and peak strength of the aldehydes and aldehyde derivatives certified reference materials.
