应用
STLC Metals CA-WET in Soil - PT is a soil/hazardous waste proficiency testing material, suitable for testing soluble threshold limit concentration (STLC) metals in soil samples by CA - Waste Extraction Test (WET) method.
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.

制备说明
Description
- The PT sample is suitable for analysis for the 16 CA STLC metals plus Mercury.
- A total sample size of 225 g is provided.
- The PT sample has been sterilized.
- 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.
- If an analyte is below your detection limit report a "<" and your detection limit or "0".
Sample Preparation
- Extraction Procedure: Thoroughly mix the sample and extract using the California WET as specified in section 66261, appendix II.
- 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.
- On the provided report form please provide all the requested information.
- 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.
