2、n the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the sampling/analysis of respi-rable suspended particles(RSP)and
3、 the estimation of the RSPfraction attributable to environmental tobacco smoke(ETS).The test method is based on collection of total RSP on amembrane filter,extraction of the filter in methanol,anddetermination of solanesol,a C45isoprenoid alcohol,by highperformance liquid chromatography(HPLC)with ul
4、traviolet(UV)detection.1.2 This test method is compatible with the determinationsof gravimetric RSP,ultraviolet particulate matter(UVPM),andfluorescent particulate matter(FPM)(see Test Method D5955),but does not require them.UVPM and FPM,which are basedon the ultraviolet absorbance and fluorescence
5、of the filterextract,are also used to estimate the contribution of ETS toRSP.1.3 The sampling components consist of a 1.0-m pore sizepolytetrafluoroethylene(PTFE)membrane filter in a filtercassette connected on the inlet end to a particle size separatingdevice and,on the outlet end,to a sampling pum
6、p.This testmethod is applicable to personal and area sampling.1.4 This test method is limited in sample duration only bythe capacity of the membrane filter.The test method has beenevaluated up to 24-h sample duration;a minimum sampleduration of 1 h is recommended.1.5 Limits of detection(LOD)for this
7、 test method at asampling rate of 2 L/min are 0.042 g/m3for 1-h sampleduration and 0.005 g/m3for 8-h sample duration.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 This standard does not purport to address all the safety
