A total suspended particle (TSP) is an archaic regulatory measure of the mass concentration of particulate matter (PM) in community air. It was defined by the unintended size-selectivity of the inlet to the filter that collected the  particles. Firstly, the filter papers were weighed before placing in the sampler. The ambient temperature and pressure were recorded. When ready to begin sampling, the protective cover was removed from the sampler and the pump was switched on. The timer was set for 4 hours and making sure the mode is in AUTO mode. After that, the on/off timer was set by pressing the PROG button until 1 ON  appeared. For this program, the beginning cycle was set by choosing the hours and week. In this experiment, the study was beginning at 2.30pm on 30 th  of September which is Tuesday. While as for the ending of the cycle, program 1 OFF  was set  by choosing the hours and week so that the sampler machine running for 4 hours. This setting was repeated for another two samplers. All of the samplers were transported to the field site and placed on a firm level surface. After 4 hours, the results of pollutants of Total Suspended Particulate (TSP), Particulate Matter (PM 10 ) and Particulate Matter (PM 2 . 5 ) were taken. The value for TSP, PM 10  and PM 2 . 5  is 22.930µg/m 3 , 20.875µg/m 3 , and 4.251µg/m 3  respectively. As a conclusion, the value of Total Suspended Particulate (TSP), Particulate Matter PM10 and Particulate Matter PM2.5 can be determined.   3 METHODOLOGY  Figure 1: Flow chart of the methodology 3)   Dried and weighted filter papers are loaded into total suspended  particulate sampler, Particulate Matter PM10 impactor and Particulate Matter PM 2.5 impactor. 1)   Sample Preparation ã   Filter papers are dried for 1 hour prior experiment. ã   The dried filter papers are weighed and the weights are recorded. 4)   The sample analyzer are transported to the field site and placed on a firm level surface. 5)   The ambient temperature and pressure are recorded. 6)   The filter papers are collected and weighed. 2)   Preparation of air particulate sampling analyzer ã   PM10 & PM2.5 impactor target disks are greased & cleaned. ã   The charged batteries are assembled with air particulate sampling analyzer. ã   The analyzer’s timer is set for 4 hours.
