Standard Practice for Development and Implementation of Instrument Performance Tests for Use on Multivariate Online, At-Line and Laboratory Spectroscopic Based Analyzer Systems

Importancia y uso:

4.1 If ASTM Committee E13 has not specified an appropriate test procedure for a specific type of instrument, or if the sample specified by a Committee E13 procedure is incompatible with the intended instrument operation, then this practice can be used to develop practical performance tests.

4.1.1 For instruments which are equipped with permanent or semi-permanent sampling accessories, the test sample specified in a Committee E13 practice may not be compatible with the instrument configuration. For example, for FT-MIR instruments equipped with transmittance or IRS flow cells, tests based on putting polystyrene films into the sample position are impractical. In such cases, this practice suggests means by which the recommended test procedures can be modified by changing the test material or the location of the recommended test material.

4.1.2 For instruments used in process measurements, the choice of test materials may be limited due to process contamination and safety considerations. The practice suggests means of developing performance tests based on materials which are compatible with the intended use of the analyzer.

4.2 Tests developed using the practice are intended to allow the user to compare the performance of an instrument on any given day with prior performance, and specifically to compare performance during calibration of the analyzer to performance during validation of the analyzer and during routine use of the analyzer. The tests are intended to uncover malfunctions or other changes in instrument operation, but they are not designed to diagnose or quantitatively assess the malfunction or change. The tests are not intended for the comparison of analyzers of different manufacture.

4.3 Tests developed using this practice are also intended to allow the user to compare the performance of a primary analyzer used in development of a multivariate model to the performance of secondary analyzers used to apply that model for the analysis of process or product samples.
