We have explored the possibility of using a continuous liquid phase of high gas permeability as a filter to remove particulate contaminants from a gas stream. The liquid, a non-toxic perfluorocarbon, severs upstream and downstream gas phases completely. It can dissolve great quantities of gases and pass them, by diffusion, along even a slight partial pressure gradient. The liquid phase remains intact in the process: there is no convective transfer of gas. Particulate contaminants will, on impact with the continuous liquid phase, lose their momentum and be stopped; our results promise near ideal efficacy of capture. We suggest that filters based on this principle be developed to protect against highly toxic particulate contaminants in an atmosphere.
我们探讨了使用具有高气体渗透性的连续液相作为过滤器，以从气流中去除颗粒污染物的可能性。这种液体是一种无毒的全氟化碳，它将上游和下游气相完全分隔开。它能够溶解大量气体，并通过扩散沿着即使是很小的分压梯度传递这些气体。在这个过程中液相保持完整：没有气体的对流传递。颗粒污染物在撞击连续液相时会失去动量并被截留；我们的结果预示着近乎理想的捕获效率。我们建议开发基于这一原理的过滤器，以防护大气中的剧毒颗粒污染物。
