称取美甲贴样品0.001 0 g置于20 mL顶空瓶中，在选定的条件下[孵化温度为36℃，孵化时间为15 min，振动器转速为300 r·min^-1，固相微萃取（SPME）温度为常温和样品的萃取次数为10次]进行顶空采样和固相微萃取，并将所得挥发性有机物（VOCs，包括所需测定的丙酮、正己烷、乙酸乙酯、乙酸异丙酯、甲苯和乙酸丁酯等6种化合物）引入气相色谱-质谱仪中进行分析。用HP-VOC色谱柱（60 m×0.25 mm，0.25 μm）在40~250℃区间以程序升温模式进行色谱分离，并在电子轰击离子源和选择离子扫描模式等条件下进行质谱测定。采用外标法定量。测得上述6种VOCs的质量在相同的范围（2~250 ng）内与其相应的峰面积呈线性关系，其检出限（3.14s）也相同（0.5 ng）。以实际样品为基体，在5个浓度水平上加入标准溶液进行回收试验，测得其回收率为80.0%~110%，测定值的相对标准偏差（n=7）为0.030%~5.0%。

0.001 0 g of the nail sticker sample was placed into the 20 mL head-space flask, and the sampling of the 6 volatile organic compounds (VOCs, i.e., acetone, n-hexane, ethyl-acetate, iso-propyl acetate, toluene and butyl acetate) together with the treatment of solid phase microextraction (SPME) was carried out under the following optimized conditions:36℃ of incubation temperature, 15 min of incubation time, 300 r·min^-1 of rate of rotation of the vibrator, normal temperature of temperature for SPME and 10 times of frequency of extraction of sample. The VOCs (including the 6 compounds mentioned above) obtained in this process were then introduced into the instrument for GC-MS analysis. The chromatographic column of HP-VOC (60 m×0.25 mm, 0.25 μm) and the mode of programmed temperature elevation from 40℃ to 250℃ were adopted in the chromatographic separation, and conditions of EI and the mode of selective ionic scanning were applied in MS determinations. Outer standard method was used for quantification. Linear relationships between values of peak areas of the 6 VOCs and their respective masses were found in the same range of 2-250 ng, with their same detection limits (3.14s) of 0.5 ng. Using substantial samples as matrixes, recovery was tested by addition of mixed standards at 5 concentration levels, giving results of recovery in the range of 80.0%-110%. Values of RSDs (n=7) were found ranged from 0.030% to 5.0%.
