| 摘 要： | 用气相色谱法分离多组分混合气体时，在一台仪器上难以实现一次性多组分全分析。设计了一种气相色谱仪精密分时检测装置，采用单机多柱联接，由计算机精确控制样品气体在色谱柱问流动与分离顺序、实现分时操作，使得测试性能上差别很大的多组分气体在单一机器测试得以实现。该系统也适用于其它需要分时操作的场合。

| Abstract: | It is a very difficult work with only one instrument to accomplish analyzing completely to multi-element and mixed gases. The precision time- sharing testing device is designed, It is composed by multi- columniation and MCU. MCU controls the sequence of sample of gas flowing between multi- columniation, and accomplish time- sharing operation. Now that, multi- element and mixed gases can be inspected on one instrument only. The device can be also used in another similar system. |
