| 英文摘要 | a direct-heating fast temperature programming device for fast gas chromatography was designed and evaluated. a metal capillary column was used both as a separation column and as a heating element. pulsed current heating strategy was used to heat the column, and at the same time, gave the time lag for self-equilibrium of the metal tubing during a temperature programming. a fast pid control was used to facilitate the fast pulse heating. the correlation coefficients of temperature programming curves were more than 0.9996 between 40-150 with tunable heating rates varying from 1 to 5 degrees c/s. the power consumption of the device was 74 w max, and was less than 50 w on average. the separation time was within 34 s for n-alkanes (nc(8)-nc(17)), with relative standard deviations of the retention times between 0.22% and 0.55%. the cool down time plus the equilibration time is less than 30 s. the device is suitable for the analysi's of semi-and volatile organic compounds in portable gc. |
