In Part I, we identified things we'd be looking for, and offered a model of "good". Now we'll do a cursory run through showing the big picture of what we're going to do. For all the samples in Ex-107's Table 3 for which we have the data, we're going to look at the F3 IRMS graph:
We should all remember that isotopic ratio has no relation to peak height. Without more ado:
No reported values available.
Ex 92 - April testing of 993865 - LNDD 1398 (Landis from 3-Jul). There is no reported value for the 5aA, with no explanation given. It could be a decision to say it has matrix interference. 5bA reported as -1.04
Exhibit for for 993856 from 11-Jul not available, reported as 5aA -2.91 and 5bA at -4.09
Ex 88 - April testing of 993855 - LNDD 1015 (Landis from 13-Jul). 5aA reported as -4.62, 5bA as -4.09
Ex 90 - April testing of 825425 - LNDD 1207 (Landis from 14-Jul), reported as -1.01, -0.70
Ex 86 - April testing of 825428 - LNDD 824 (Landis from 18-Jul). Reported as -5.06, -3.56
USADA 173, reported as 5aA -6.14, 5bA -2.15, Andro (other fraction) -3.99. Done on the IsoPrime1 machine with different software, so the display is different.
USADA 349, the Stage 17 B sample, reported as 5aA -6.39, 5bA -2.15, and Andro -3.51. Also done on the Isoprime1 with different display.
Ex 87 - April testing of 825429 - LNDD 922 (Landis from 22-Jul). Reported as -5.06, -3.56
Ex 84 - April testing of 825424 - LNDD 633 (Landis from 23-Jul). Reported as -4.96, -1.45.
Ex 93 - April testing of 825427 - LNDD 1492, the ocean blue, (Aguilera control), reported at 5aA -1.31, 5bA -0.95
Ex 85 - April testing of 825426 - LNDD 730 (Aguilera control), reported as 5aA -0.77, 5bA -0.88
Ex 89 - April testing of 825423- LNDD 1193 (Aguilera control), reported at 5aA -1.21, 5bA -0.79
We'll zoom into the regions of interest in following parts of this series.
