Application
TCLP Metals in Soil - PT is a soil/hazardous waste proficiency testing material, suitable for testing TCLP metals in soil samples.Our soil PT samples behave as real samples; and, unless there is no alternative, are not simply spikes added to a blank soil. They are designed to meet the requirements of national, regional and state-specific accreditation bodies (TNI, USEPA, UKAS) for quality assurance and continuous improvement.Have any questions?

Preparation Note
Description The PT sample is suitable for analysis for the eight TCLP metals. A total sample size of 225 g is provided. The PT sample has been sterilized. Once opened sample should be used within 6 months or by the expiration date on the label, whichever is sooner. The evaluation of results will be based on study statistics for equivalent methods. At least two analytes are above the regulatory limit. Some analytes may not be present at recoverable levels.Sample Preparation Extraction Procedure: Thoroughly mix the sample and extract an accurately weighed portion (approximately 100 grams) of the material using SW846 Method 1311; Toxicity Characteristic Leaching Procedure. Prepare the extract for metals analysis by using the appropriate digestion procedure for the analysis technique selected. The sample may be analyzed by any combination of inductively coupled plasma (ICP) and atomic absorption (AA) methods. Provide all the requested information. Do not correct the analytical results for matrix spike recovery bias. Digestion Procedures: Prepare the TCLP extracts for metals analysis using the methods for which you are seeking accreditation. There is sufficient TCLP extract to perform all digestions. If a sample digestate contains particulates that may clog your instrument, remove them by filtration, or by centrifugation (see appropriate method for guidance). Analyze the digestate solutions using the appropriate determinative methods for which you are seeking accreditation. The method used must be reported for each analyte.
