| Description | A summary of the analytical results from 4 mini-grab sample (mGSCs) collected on ISS and returned aboard 33S is shown in Table 1. Due to the launch delay of the ATV4 resupply mission, monthly samples were reduced in April and May by omitting sampling of the Service Module in order to ensure contingency samplers were available if needed. Complete data tables of all measured concentrations and corresponding T-values based on 180-day SMACs are enclosed. detection limit for all target compounds, except m/p-xylenes and hexachloro-1, 3-butadiene was 0.025 mg/cu m. The detection limit for m/p-xylenes and hexachloro-1, 3-butadiene and all non-target compounds was 0.05 mg/cu m. The average recoveries of the 3 surrogate standards from the mGSCs were as follows: C-13-acetone, 116 +/- 12%; D-5-fluorobenzene, 117 +/- 7%; and D-5-chlorobenzene, 111 +/- 15%. Initial measured sample pressures were between 13.9 and 14.1 psia for all samples, indicating nominal sample collection. A summary of the analytical results from 3 pairs of passive-diffusion formaldehyde badges collected on ISS and returned aboard 33S is also provided in Table 1. In an effort to conserve samples due to the delay of the ATV4 resupply mission, FMK sampling was only conducted in the US Lab in May. Positive control recoveries (1 trip and 2 lab controls) were 79%, 87%, and 116% respectively. |
