Effect of Using VHG Metallo-Organic Concentrates in Production of JOAP Spectrometric Standards
Abstract
The previous sole source supplier of metallo-organic concentrates used in the production of JOAP calibration/standardization fluids made a business decision (0 discontinue the sale of its concentrates. This decision was a signal to the Joint Oil Analysis Program Technical Support Center (JOAP-TSC) to begin the search for and qualification of new suppliers of concentrates. The JOAP-TSC tested the effects from using VHG Labs, Inc. metallo-organic concentrates in the preparation of JOAP spectrometric standards. The new VHG-based standards were blended and QC tested according to normal JOAP-TSC production methods. Once accepted, the standards would be further tested for their effects on the Joint program in used oil sample testing. Used oil tests were performed to show the comparability of results obtained on spectrometers calibrated/standardized with either VHG or Conostan blends. The purpose of the tests was to ensure that the limits in the JOAP Manual Volume 3 would not change. Testing demonstrated that the JOAP blends prepared from the concentrates manufacwred by VHG Labs, Inc. met the requirements of the JOAP and are interchangeable with current JOAP standards.
