  1. ISO/IEC 17043:2010 Proficiency Testing Program for Multiple-Laboratory/ Multiple Instrument Data Validation of Petroleum Products. 13 March 2012 PITTCON 2012 Roland St. Germain* Mike Travers Tim Alavosus, Ph.D.

  2. VHG Labs has developed a Proficiency Testing Program (PTP) to measure: Elements in oil by ICP or RDE Kinematic Viscosity Elements in Lube oil by XRF Sulfur in various matrices PB Lead in Isooctane VHG Labs' Original Proficiency Testing Program (PTP)

  3. Proficiency Testing Program (PTP)

  4. What is Proficiency Testing? • Proficiency Testing is a regular evaluation of your laboratory instrumentation as compared to independent certified reference materials.

  5. Many laboratories rely on their own instrument calibration techniques as their sole method of calibration verification. Why Use Proficiency Testing?

  6. Confirm Instrument Performance Demonstrate Competitive Advantage Provide Greater Confidence Levels for Your Lab’s Customers Shift/Operator Verification Specific Benefits of Regular Proficiency Testing:

  7. There can often exist a bias from one instrument to another of the same general type based upon: design (i.e., different mfg or model) operating parameters methodology conditions used environmental factors. Why Use Proficiency Testing?

  8. It is useful to have a program that regularly determines the relative correlation of one or more instruments within the same laboratory facility or different locations. Why Use the PTP?

  9. Historically, Proficiency Testing often used a Round-Robin approach. This method is painful and tedious. It takes so long, it is a poor method of instrument evaluation, as so many parameters are likely to change over time. It does not benefit from the use of modern technology and instant performance evaluation More about Proficiency Testing

  10. How the original VHG PTP Works: You order the type of test(s) you want PTP is sent directly to your lab with login password You run the samples at your convenience, whenever you want Enter results into www.vhglabs.com You Receive the resultsIMMEDIATELY!

  11. VHG Labs’ PTP provides a method for validation of ICP, XRF and viscosity. The VHG Labs PTP is currently the only program of its kind to provide an instant response to submitted values, with convenient color-coded pass/fail indications in green (pass), yellow (borderline), andred (fail). Proficiency Testing Program (PTP) from VHG Labs

  12. In case you asked… Currently Assigned Values for ICP Metallo-organic PTP test For all certified values > 20 ppm: Green = within +/- 10% Yellow = within +/-15% Red > 15% < 20 ppm: Green = within +/- 1ppm Yellow = within +/-2ppm Red > 2ppm These values may be customized as an added-value option. Color feature not available for Viscosity tests.

  13. The PTP User Interface ALL ONLINE: Simply type in your results… 100 Then: 105 112 121 102 100

  14. The PTP User Interface Validation is automatic and instantaneous

  15. In ICP analysis, there are several common possible sources of error: Sample Preparation Sample Introduction Sipper Probe Pump Tubing Nebulizer Torch: O-rings, fittings, and connections -Possible air leaks How Does the PTP Help?

  16. VHG NEW ISO 17043 PTP The new PTP is designed to provide laboratories with a method of monitoring their analytical performance measured against samples that are ISO/IEC 17043 compliant.

  17. ISO/IEC 17043:2010 VHG Labs PTP incorporates the requirements for 17043: Normalized Error (En). (Note: 17043 response is not instantaneous)

  18. Takes performance testing further Provides guidelines for error ranges These are based on calculations of laboratory uncertainties These uncertainties are called “Normalized Error”, or En You can calculate this easily ISO/IEC 17043:2010

  19. En is “error, normalized” and is calculated as: En = (xlab – xVHG )/√(U2lab + U2VHG ) Where: xlab is your analytical result xVHG is the VHG Certified Value Ulab is the expanded uncertainty that you reported UVHG is the expanded uncertainty of the VHG Certified Value (95% coverage) ISO 17043: Normalized Error

  20. Basis for Pass/Fail Criteria Pass = -1< En <+1 (Green) Fail = En <-1 or En > +1 (Red)

  21. ISO/IEC 17025 PT ISO Registrars strongly recommend the use of ISO 17043 PTP when performing required Proficiency Tests for ISO/IEC 17025 accreditation.
