Description

General description

VOAs in Soil - Medium Level - PT proficiency testing material is produced in accordance with ISO/IEC 17043:2010. This product is produced according to TNI requirements. However, please note, this sample may include non-TNI analytes as well. The PT portfolio allows our test components to offer significant performance data to monitor and prove competency to customers, accreditation bodies or both.

Supelco^® is a global proficiency testing (PT) provider that manufactures best-in-class environmental and pharmaceutical PT products. We are the world leader in the manufacturing of real-world soil, sediment and sewage sludge PT products.

Type of PT Scheme: Solids/Soils/Hazardous Waste

Matrix: Soil

Analyte/s: Randomly contains a minimum 60% of the analytes listed. Values of analytes vary lot to lot.

All information regarding the use of VOAs in Soil - Medium Level - PT can be found in the reporting packet which will be available to download at PT Portal.

Application

VOAs in Soil - Medium Level - PT is a soil/hazardous waste proficiency testing material, suitable for testing volatile organics 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.

Features and Benefits

We have a vast portfolio of environmental PT schemes with "fit-for-purpose" samples to help you meet the needs of the laboratory.

Our proficiency testing (PT) program is a benchmark to:

• provide staff with an insight into their laboratory′s performance, to verify the accuracy and reliability of their testing process
• provide a comparison of performance with that of other laboratories, nationally and internationally
• test and educate staff, provide a better understanding of the impact of incorrect results and identify areas where there may be problems
• provide an independent evaluation of laboratory performance
• demonstrate to clients, colleagues and accreditation bodies that there is a commitment to quality

Preparation Note

Description

NOTE: The reporting units have changed to μg/Kg for all analytes to meet TNI requirements. The concentrations have remained the same.

• This standard consists of 25 g of soil containing volatile organics.
• The soil has been chemically stabilized with 25 mL of methanol to minimize the degradation of the sample.
• The evaluation of results will be based on study statistics as required by TNI standards.
• This standard may not contain all the compounds listed on the Report Forms in accordance with TNI standards. For analytes not detected report a zero "0" or a "<" and your detection limit.
• This PT sample is intended for methods USEPA SW846 Method 8240 and 8260 using methanol or purge and trap extraction (EPA 5030).

Sample Preparation

• The sample is provided pre-extracted with methanol as specified by USEPA Method 5030.
• Shake sample for two minutes prior to sampling.
• Using a gas-tight syringe, aliquot 100 μL of methanol extract and inject into your purge and trap vessel below the surface of 5 or 25 mL of organic-free water. Using more than 100 μL may exceed the trapping capacity and detector response of the purge and trap system.
• After sampling, tightly reseal the vial ensuring there is no sample remaining between the vial rim, threads and cap.
• Immediately complete other sample preparation according to your analytical procedures.
• To calculate your results, use 25 g as the sample weight and 25 mL as the extraction volume. Report results as μg/kg.
• Report on a wet weight basis, do not correct results for moisture content.
• Provide all the requested information; note that the results of the analysis are to be reported on a wet weight basis.
• The method used must be reported.

Storage and Stability

Please refer to sample label for expiration date, specific storage temperature, and specific storage conditions.
