§1065.267. Gas chromatograph with a flame ionization detector.
40 C.F.R. § 1065.267
Application. You may use a gas chromatograph with a flame ionization detector (GC-FID) to measure CH4 and C2H6 concentrations of diluted exhaust for batch sampling. While you may also use a nonmethane cutter to measure CH4, as described in § 1065.265, use a reference procedure based on a gas chromatograph for comparison with any proposed alternate measurement procedure under § 1065.10.
Component requirements. We recommend that you use a GC-FID that meets the specifications in § 1065.205 and that the measurement be done according to SAE J1151 (incorporated by reference, see § 1065.1010). The GC-FID must meet the linearity verification in § 1065.307.
