Section 1065.267 - Gas chromatograph with a flame ionization detector(a)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 .(b)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 . 76 FR 57442 , Sept. 15, 2011, as amended at 79 FR 23761 , Apr. 28, 2014; 81 FR 74163 , Oct. 25, 2016; 89 FR 29796 , Apr. 22, 2024 81 FR 74163 , 12/27/2016; 89 FR 29796 , 6/21/2024
