Metal Alloy Proficiency Testing Program (PTP)

ISO 17043 Accredited

Our unique metal alloy Proficiency Testing Program (PTP) is the only program that measures analytical performance against a CRM’s “Assigned Value”, and has been used in the metals industry for more than 30 years. This PTP was developed as an alternative to typical round-robin style proficiency testing schemes, which only measure performance with non-certified materials.  Our PTP is accredited to ISO 17043.

It is important to monitor the quality of your analytical results, as stipulated in the ISO/IEC 17025 laboratory accreditation process. Our PTP gives you that ability with an unbiased and confidential assessment of your analytical performance against peer performance. Whether you have a single-instrument or a multiple-instrument/multiple-technique environment, our PTP is a trouble-free QA program that is traceable to NIST values, and can be easily integrated into your lab processes.

How it works

• You select the date and frequency (monthly, quarterly, biannually or annually).
• You choose the type of material by matrix group and sample configuration (solids, chips or pins).
• We send you a blind sample from our stock of CRMs based on your selection. 
• You analyze the blind sample, and email or fax your results to us.
• You receive your report within  1 week.  All results are confidential.

Matrix Types

Your report will include

• A color-coded Certificate of Performance which compares your results to the actual benchmark data
• A color-coded control chart graphically depicting your data compared to the certified average for each element examined
• A Certificate of Analysis confirming that a CRM was used in the test
