A NEW FILTERBAND MATERIAL FOR THE SEQUENT IAL SAMPLING OF AMBIENT AEROSOLS WITH SUBSEQUENT TRACE-ELEMENT ANALYSIS

A quartz fiber filtermaterial in the form of a filterband was develope d for trace element analysis in ambient aerosols. Previous available f ilterbands mode of glass fibers are suitable for automatic dust sample rs with regard to their mechanical properties but contain too high bla nk concentrations to analyze short time collected samples for their tr ace element content. With the use of the new developed filtermaterial in automated dust samplers it is possible, to monitor the situation of immission continuously. The filter was also intended to be used in ma rine regions where low trace element concentrations ore present. Lower ing the blank values of the filterband allows its use in emission cont rol for those elements mentioned in recent clean air regulation acts ( TALuft and 17, BImSchV) [1].
