The concentration of n-hexane in urine was determined in 30 subjects occupationally exposed to n-hexane (median value 59.6 mg/m3) in a shoe factory. The measurement of the substance was performed by means of a Hewlett-Packard 5880 gas chromatograph supplied with a Hewlett-Packard 5970 Mass Selective Detector. The analyses were performed by the head space method (constant volume method, after determination of the urine partition coefficient by the multiple phase equilibration method). The authors found a significant correlation between the n-hexane urine concentrations (microgram/l, Cu) and the n-hexane environmental concentrations (mg/m3, Ci) (r = 0.84; Cu = 0.0669 X Ci + 0.8396).
对一家鞋厂中30名职业性接触正己烷（中位值59.6毫克/立方米）的受试者的尿中正己烷浓度进行了测定。该物质的测量借助配备惠普5970质量选择检测器的惠普5880气相色谱仪进行。分析采用顶空法（定容法，通过多相平衡法测定尿液分配系数后）。作者发现尿中正己烷浓度（微克/升，Cu）与环境中正己烷浓度（毫克/立方米，Ci）之间存在显著相关性（r = 0.84；Cu = 0.0669×Ci + 0.8396）。
