| 摘要: |
| 采用固相微萃取和气相色谱相结合的技术,建立了凹印油墨VOC的测试方法。通过对萃取时间、萃取温度和萃取纤维涂层膜厚等影响萃取效率的因素进行研究，获得了优化的测试条件。结果表明，气相色谱柱温箱升温程序为：50 ℃开始以50 ℃/min升至200 ℃，然后再以10 ℃/min升至230 ℃，保持5 min；固相微萃取最佳萃取条件为：萃取时间20 min，萃取温度80 ℃，采用100 μm PDMS的萃取纤维。 |

| Abstract: |
| A method for measuring volatile organic compound (VOC) in gravure ink was established by using Gas chromatography (GC) and SPME technology. The influencing factors on extracton efficiency including extraction time, extraction temperature, and film thickness of SPME coating fiber were optimized. The experiment results showed that GC oven temperature program was seting at an initial temperature of 50 ℃, raising to 200 ℃ at 50 ℃/min, then raising to 230 ℃ at 10 ℃/min, and hold for 5 min. An extraction time of 20 min and an extraction temperature of 80 ℃ were the optimized SPME extraction conditions. A 100 μm polydimethyl-siloxane (PDMS) SPME fiber was selected. |
