They DO NOT reflect inaccuracies of the calibration values assigned to our standards. 1 GMTs F11 F11e F113 F113e MC MCe CT CTe N2O N2Oe SF6 SF6e F12 F12e H1211 H1211e H2 H2e CH4 CH4e 79609 264.3 7.5 79.7 1.7 99.6 2.6 106.0 3.3 9999 999 9999 999 521.1 14.6 3.80 0.29 9999 999 9999 999 79789 264.9 7.5 81.4 1.7 96.1 2.6 101.4 3.3 313.4 5.6 3.46 0.06 514.4 14.3 3.57 0.26 574 12 1786 97 79969 241.5 6.0 77.7 1.6 91.5 2.5 92.3 3.2 9999 999 9999 999 491.1 13.3 3.01 0.20 557 12 1684 97 80149 264.4 7.5 81.8 1.7 95.8 2.6 101.2 3.3 299.8 5.4 3.41 0.05 521.8 14.7 3.48 0.25 550 12 1721 97 80509 236.5 5.7 77.2 1.6 87.2 2.5 87.4 3.1 289.3 5.1 3.25 0.05 484.0 13.0 2.85 0.18 548 12 1632 97 80689 232.0 5.5 76.2 1.6 86.0 2.5 84.1 3.1 9999 999 9999 999 470.9 12.5 2.62 0.16 550 12 1619 97 80869 219.3 5.0 73.5 1.6 81.7 2.5 79.5 3.0 279.4 5.0 3.22 0.05 456.7 12.0 2.43 0.15 553 12 1556 97 81049 165.1 3.6 62.2 1.5 61.2 2.4 56.0 2.9 9999 999 9999 999 392.4 10.0 1.66 0.10 557 12 1436 97 81409 189.1 4.1 67.5 1.5 70.9 2.5 67.9 3.0 9999 999 9999 999 423.5 10.9 2.03 0.12 552 12 1528 97 81589 189.6 4.1 67.3 1.5 71.5 2.5 69.5 3.0 260.1 4.6 2.94 0.05 424.2 10.9 2.05 0.12 558 12 1559 97 81769 186.6 4.0 67.0 1.5 71.6 2.5 9999 999 9999 999 9999 999 415.6 10.6 1.95 0.11 567 12 1556 97 81949 274.4 8.4 83.2 1.7 98.2 2.6 105.2 3.3 311.8 5.6 3.55 0.06 517.6 14.5 3.48 0.25 553 12 1798 97 82309 9999 999 84.9 1.7 102.5 2.6 110.0 3.4 316.6 5.7 3.73 0.06 530.0 15.1 3.76 0.29 535 12 1895 98 82489 285.5 9.6 84.1 1.7 101.3 2.6 9999 999 9999 999 9999 999 529.0 15.0 3.81 0.29 524 12 1729 97
