本文介绍了一种高性能低功率微气相色谱柱的原理、制备方法和实验结果。1米长的悬浮电介质柱被分成两个部分，允许独立的压力和温度编程。集成柱式加热器的平均电阻为16.8 kOmega，电阻温度系数为431 ppm/℃。悬浮柱需要11mw才能在真空（1mtorr）中将其温度提高100℃。色谱柱在52秒内分离出10种挥发性有机化合物，在60秒内分离出4种化学战剂模拟物和1种爆炸模拟物。
This paper presents the theory, fabrication, and experimental results for a high-performance low-power micro gas chromatography column. The suspended-dielectric 1-m-long column is split into two sections, permitting independent pressure and temperature programming. Integrated column heaters have a mean resistance of 16.8 kOmega and a temperature coefficient of resistance of 431 ppm/degC. The suspended column requires 11 mW to raise its temperature by 100degC in vacuum (1 mtorr). The column separates ten volatile organic compounds in 52 s and four chemical warfare agent simulants and an explosive simulant in 60 s.
