EN ISO 22892 Chromatographic Analysis of Soils
The EN ISO 22892 standard specifies a comprehensive methodology for the chromatographic analysis of soils, focusing on the determination of volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs). This service is essential in environmental monitoring, waste management, and remediation projects. Soil contamination can lead to significant ecological and health risks, making accurate and reliable testing critical.
Chromatographic analysis involves the separation of components within a mixture based on their different interactions with a stationary phase and mobile phase. The process allows for precise quantification and identification of target compounds in complex matrices such as soils. EN ISO 22892 ensures that soil samples are prepared, analyzed, and reported according to internationally recognized standards.
The procedure typically begins with the collection of representative soil samples from various depths within a site. Samples must be stored under controlled conditions until analysis can take place. The extraction process is crucial in ensuring that all target compounds are brought out into solution for subsequent chromatographic separation. Common solvents used include hexane, dichloromethane, and acetonitrile.
The chromatographic system employed should adhere to the specifications outlined in EN ISO 22892. This includes the use of a gas chromatograph (GC) or liquid chromatograph (LC), depending on the nature of the compounds being analyzed. The column types vary based on polarity, length, and diameter, which are selected for optimal separation efficiency.
Following extraction and injection into the chromatographic system, data is collected and processed using advanced software to generate accurate peak identification and quantification. Peak integration techniques ensure precise measurement of compound concentrations within the sample matrix. The method's selectivity and sensitivity allow for the detection of very low levels of contaminants, making it suitable for both routine monitoring and forensic investigations.
Reporting adheres strictly to the requirements specified in EN ISO 22892, providing detailed information on the identity, concentration, and recovery rate of each detected compound. This data is invaluable for environmental risk assessment, regulatory compliance, and remediation planning. Compliance with this standard ensures that results are credible and universally acceptable.
