NORMALIZING ANALYZER SYSTEMS TO A STANDARD ANALYZER

摘要

NORMALIZING ANALYZER SYSTEMS TO A STANDARD ANALYZER There is described a method of calibrating an analyzer in the field, using parameters designed for a "standard" analyzer that may be different from the field analyzer. In this way, it is not necessary to use only certain slide elements of a given chemistry on one analyzer, and certain other slide elements of that same chemistry on another analyzer. Instead, the slide elements are made interchangeable by calibration math which allow the field analyzer to convert its raw response RF into a response Rstandard of the selected "standard" analyzer, using the equation (1) Rstandard = B0 + B1 ? RF + B2 ? (RF)k . The coefficients of this equation are established by comparing, at at least 1 different level of response, RF against Rstandard, optionally using an intermediate spline function gF(RF) in place of RF.
