General description

Trace Metals 1 - 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 product is produced 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. 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. 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 in compliance with Discharge Monitoring Report - Quality Assurance Program (DMR-QA), 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.

  • provide an independent evaluation of laboratory performance
  • demonstrate to clients, colleagues and accreditation bodies that there is a commitment to quality

Preparation Note

Description

  • This PT sample is packaged as a 20 mL concentrate.
  • The solvent for this sample is 5% nitric acid by volume in DI water.
  • The PT sample has not been preserved.

Sample Preparation

  • To prepare the solution, partially fill a 1000 mL volumetric flask with reagent-grade water (near 20 ºC) and add 1 mL of trace-metal-grade nitric acid.
  • Open ampule PE1132-20ML (be careful to avoid cuts on glass) and transfer 10.0 mL of concentrate to the volumetric flask.
  • Fill the flask to volume with reagent-grade water and mix well.
  • The sample is now ready for immediate digestion and analysis, as per laboratory SOPs.
  • A reagent-grade blank should be analyzed concurrently for background correction.
  • The water blank should be made to match the acid matrix of the standards and samples.
  • Each analyte is reported in μg/L.

NOTE: The 0.15% v/v nitric acid specification is a minimum; the amount and type of acid may be altered to routine analytical procedures if needed.
NOTE: Mercury can be present as both inorganic and organic mercury.

Storage and Stability

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