3、yridine(3-EP)in indoor air.This testmethod is based upon the collection of nicotine and 3-EP byadsorption on a sorbent resin,extraction of nicotine and 3-EPfrom the sorbent resin,and determination by gas chromatog-raphy(GC)with nitrogen selective detection.(1)21.2 The active samplers consist of an X
4、AD-4 sorbent tubeattached to a sampling pump.This test method is applicable topersonal or area sampling.1.3 This test method is limited in sample duration by thecapacity of the XAD-4 tube for nicotine(about 300 g).Thistest method has been evaluated up to 24-h sample duration;however,samples are typi
5、cally acquired for at least 1 h(sometimes only 1 h).(2)1.4 For this test method,limits of detection(LOD)andquantitation(LOQ)for nicotine at a sampling rate of 1.5 L/minare,respectively,0.11 g/m3and 0.37 g/m3for 1-h sampleduration and 0.01 g/m3and 0.05 g/m3for 8-h sampleduration.The LOD and LOQ for 3
6、-EP at a sampling rate of 1.5L/min are,respectively,0.06 g/m3and 0.19 g/m3for 1-hsample duration and 0.01 g/m3and 0.02 g/m3for 8-h sampleduration(2).Both LOD and LOQ can be reduced by increasingthe sensitivity of the thermionic specific detector.1.5 UnitsThe values stated in SI units are to be regar
