§ 1065.369 - H2O, CO, and CO2 interference verification for photoacoustic alcohol analyzers.
(a) Scope and frequency. If you measure ethanol or methanol using a photoacoustic analyzer, verify the amount of H
(b) Measurement principles. H
(c) System requirements. Photoacoustic analyzers must have combined interference that is within (0.0 ±0.5) µmol/mol. We strongly recommend a lower interference that is within (0.0 ±0.25) µmol/mol.
(d) Procedure. Perform the interference verification by following the procedure in § 1065.375(d), comparing the results to paragraph (c) of this section.
