Abstract:
Weighing collected samPles to determine the IPS' content of indoor air and adopting the length of collecting time as 4 , 6and8 hours, the experimental accuracy and analytic errors were seParatdy analysed in different length of collecting time, as a result, when the IPS' content is less than 0.300mg.m-3, the smallest co-fficient of variation came from the statistic result of which its length of collecting time was 8 hours and in anaylsis its Permissible relative errors were not more than 10%, so it could be determined that the apporiate length of ccollecting time was 8 hours ( CIP
