Abstract

Preparation of samples of known concentration of hydrogen fluoride, arsine and phosgene in air from 0.5 to 10 times the TLV is described. These are required to evaluate and calibrate analytical monitoring devices used for measuring these gases in work atmospheres. Dynamic gas-blending systems have been constructed and evaluated at the National Bureau of Standards for preparing these samples. Measurements to estimate the long term concentration stability of these gases are also included.

摘要

本文描述了如何制备空气中氟化氢、砷化氢和光气浓度已知的样品，其浓度范围为阈限值（TLV）的0.5至10倍。制备这些样品是为了评估和校准用于测量工作环境中这些气体的分析监测设备。美国国家标准局已构建并评估了用于制备这些样品的动态气体混合系统。文中还包括了对这些气体长期浓度稳定性的评估测量。
