16、 dispenser interfaces.The particu-late concentration is determined by dividing the particulateweight,which is the difference of filter weights before and aftersampling,by the total volume of hydrogen or other gaseousfuel passing through a filter.Every precaution should be takento avoid contamination of particulates 10 m or larger onto thefilter coming from the PSA,the analytical system,ambient air,filter handling or other environmental sources.5.Significance and Use5.1 Low operating temperature
