PT Program Study Catalog

Introduction

Through the Supelco portfolio of analytical products and as a global proficiency testing (PT) provider, SigmaAldrichRTC manufactures best in class food, clinical, environmental and pharmaceutical PT Products with its ISO 17043 accreditation. The PT portfolio allows our customers in many different market segments to assess performance of laboratory employees and instrument and control the accuracy and precision of methods. The Supelco PT portal offers significant performance data to monitor and prove competency to customers and accreditation bodies. 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

Residue on Ignition (ROI) | PEP006-3X1G

General Instructions

  1. Ignite suitable crucibles at 600 °C ± 50 °C for 30 minutes, cool in a desiccator and weigh accurately. Weigh accurately approximately 1 g of the test sample into the crucible. Moisten with about 1 mL of sulfuric acid and heat gently by an appropriate method until the sample is thoroughly charred. Cool then repeat with another portion of sulfuric acid (about 1 mL) until white fumes are no longer evolved. Then ignite at 600 °C ± 50 °C until the residue is completely incinerated. Calculate the % of residue. Repeat process until constant weight % is achieved. **NOTE** Smaller quantities of test sample may be used.
