PR-312-17204-R01 Portable Analyzer Method Update - Phase 2

This report provides status and results after completing Phase 2 of an ongoing project to develop a simplified test method for portable analyzer emissions tests. The Phase 1 report provided the technical rationale for simplifying procedures (e.g., calibration) and reducing associated costs based on the inherent linearity associated with the physical properties of electrochemical cells, which are the analytical technology used in current generation electrochemical analyzers. The Phase 1 report also identified the primary criteria for the simplified methodology.

This document provides a listing of related PRCI project documents, including the project plan, the draft test method, and the data gaps memo. The main focus of this report is to present results of lab and field experimentation conducted in 2016 and 2017 designed to address the data gaps. Portable analyzer manufacturers (Testo, AMETEK, and ECOM) demonstrated support for this project via cofounding and participation in experimentation and draft method discussions. The conclusions drawn from the experimentation in support of draft method revisions will be discussed in greater detail in the final report.
