Sampling and analysis of aerosols generated by plasma are cutting of stainless steel have qualitatively demonstrated particle penetration of sampler prefilters utilized in the National Institute for Occupational Safety and Health (NIOSH)-type and impinger sampler analytical procedures for measuring the presence of nickel carbonyl. These results illustrate that only a small mass of nickel-containing particles need penetrate the prefilters to exaggerate greatly the inferred concentration of nickel carbonyl. Strong evidence was obtained via the chemiluminescence method that nickel carbonyl concentrations in fact were very low (less than 1 ppb).
对等离子体切割不锈钢产生的气溶胶进行采样和分析，已经定性地证明了在美国国家职业安全与健康研究所（NIOSH）类型的采样器以及用于测量羰基镍存在的冲击式采样器分析程序中所使用的采样器预过滤器存在颗粒穿透现象。这些结果表明，只需少量含镍颗粒穿透预过滤器，就会极大地夸大推断出的羰基镍浓度。通过化学发光法获得了有力证据，表明羰基镍的实际浓度非常低（低于1 ppb）。
