摘要:
The present disclosure relates to a method of collecting particles in a gas sample comprising impacting particles in the gas sample on a porous material, as well as to impactors wherein an inertial impactor includes a porous substrate.
摘要:
A denuder for collection of gases, consisting of a plurality of generally parallel elongated tubes having a surface formed from an inert non-metallic material, said tubes being configured and arranged to allow recovery of gaseous material collected on each said surface.
摘要:
Disclosed is a dry single tube fiber optic cable of the loose tube variety in which there is no filling or flooding materials but none the less adequate provisions are made to protect the optical fibers from damage due to water penetration. The cable structure comprises (1) one or more groups of optical fibers each held together by a circumscribing water absorbent material; (2) a buffering tube having an internal channel larger than the one or more groups of optical fibers in which the groups of optical fibers are moveably disposed; (3) a strength member circumscribing the buffering tube; (4) a water absorbent material circumscribing the strength member, and (5) a jacket circumscribing the strength member.
