Abstract
Particle count measurements have been made on filtered N2 passed through a 30 ft section of 0.18″ i.d., 316L stainless steel tubing that had seen extended service as a delivery line for dry HCl. Experiments of two hours duration were run in sequence at N2 flowrates of 0.14, 0.33, 0.43 and 1.0 CFM. The corresponding flow Reynolds numbers were 1200, 2900, 3800 and 8800. A PMS Model LAS-X particle counter tallied particles within a 0.3 1pm exit sample stream over 10 minute time intervals. Counts were made for fifteen equistep size classes between 0.17 and 0.62 urn, as well as for all particles ›0.62 μm.
