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

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

6 Specific Benefits of Regular Proficiency Testing: 1. Confirm Instrument Performance 2. Demonstrate Competitive Advantage 3. Provide Greater Confidence Levels for Your Lab’s Customers 4. Shift/Operator Verification

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

9 More about Proficiency Testing Historically, Proficiency Testing often used a Round-Robin approach. 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

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

11 Proficiency Testing Program (PTP) from VHG Labs VHG Labs’ PTP provides a method for validation of ICP, XRF and viscosity. 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), and red (fail). 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), and red (fail).

12 In case you asked … Currently Assigned Values for ICP Metallo-organic PTP test For all certified values > 20 ppm: > 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.

14 The PTP User Interface Validation is automatic and instantaneous

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

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

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

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

19 ISO 17043: Normalized Error En is “error, normalized” and is calculated as: E n = (x lab – x VHG )/√(U 2 lab + U 2 VHG ) Where: x lab is your analytical result x lab is your analytical result x VHG is the VHG Certified Value U lab is the expanded uncertainty that you reported U VHG is the expanded uncertainty of the VHG Certified Value (95% coverage)

20 Basis for Pass/Fail Criteria Pass = -1< E n <+1 (Green) Fail = E n +1 (Red)

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