一般描述
ORBO 502 Activated Silica Gel (20/45) 100/50 mg sorbent tubes (W,W,F separators, O.D. × L 6 mm × 75 mm) contain two beds of the same selective adsorbent separated by glass wool or foam, for gas and vapor sampling. The dual-layer or two-bed construction of the tube allows for any sample breakthrough to be captured in the smaller back-up bed.
