介绍了作业场所空气中萘的毛细管气相色谱测定方法。本方法灵敏度高 ,准确性好 ,操作快速、简便。方法的精密度 :CV=3.5%～5.9 %;准确度 :加标回收率为95.8%～98.1 % ;最小检出量为 :2×10-4μg(进样体积为0.2μl液体样品 )。 The method for the determination of naphthalene in the workplace by capillary gas chromatography was introduced. The method has high sensitivity, good accuracy, quick and easy operation. The accuracy of the method: CV = 3.5% ~ 5.9%; accuracy: spiked recoveries ranged from 95.8% to 98.1%; the minimum detectable amount was 2 × 10-4μg (injection volume was 0.2μl liquid sample).
