General description: | Silica - WP proficiency testing material is produced in accordance with ISO/IEC 17043:2010. Also referred to as non - Potable Water or Water Pollution sample, this sample is manufactured according to TNI requirements. However, please note, this sample may include non-TNI analytes as well. The higher criteria from the TNI tables mimic the levels common to wastewater samples. Supelco® is a global proficiency testing (PT) provider that manufactures best-in-class environmental and pharmaceutical PT products. Most water PT samples are available as concentrates or ready-to-use volumes giving the end-user flexibility in selecting samples that will fit their exact needs. Our WP program is designed to meet the quality assurance requirements, thereby ensuring the analytical competence of your laboratory. These samples are typically provided in duplicate for use in case of lab mishap, for QC purposes or to analyze multiple methods. Type of PT Scheme: Water Analysis - Water Pollution (WP) Matrix: Water Pollution/Wastewater Analyte/s: Values of analytes vary lot to lot. All information regarding the use of Silica - WP proficiency testing standard can be found in the reporting packet which will be available to download at PT Portal ![]() |
