ISO 17191:2004规定了通过原子吸收光谱法（AAS）测量钠（Na）来测定空气粉尘中聚丙烯酸酯（PA）高吸水性粉末的方法。PA粉尘样品收集在聚苯乙烯丙烯腈空气监测盒中，带有聚四氟乙烯过滤器和多孔塑料衬垫。 本方法适用于测定0.2微克至60微克（检测限接近0.2微克）的高吸水性粉末。

ISO 17191:2004 specifies a method for the determination of polyacrylate (PA) superabsorbent powders in airborne dust by measurement of sodium (Na) by atomic absorption spectrometry (AAS). PA dust samples are collected in polystyrene acrylonitrile air-monitoring cassettes with polytetrafluoroethylene filters and porous plastic backing pads. This method is applicable to the determination of collected superabsorbent powder in the range between 0,2 micrograms and 60 micrograms (limit of detection near 0,2 micrograms) of superabsorbent powders.
