一种毛细管气相色谱柱可控加压或抽真空装置
摘要：
本实用新型涉及一种毛细管气相色谱柱可控加压或抽真空装置，用于为毛细管注入待充固定液或抽真空，包括多通阀、与所述多通阀连接的稳流阀、与所述稳流阀连接的两个气体压力调节阀、分别与所述两个气体压力调节阀连接的两个压力表、分别与所述两个压力表连接的两个流量计、分别与所述两个流量计连接的两个泄压阀、以及分别与所述两个泄压阀连接的两个加压装置，所述多通阀与气瓶或真空安全瓶相连接，所述加压装置内装有待充固定液，所述毛细管伸入所述加压装置内的待充固定液内。该毛细管气相色谱柱可控加压或抽真空装置具有安全，高效，环保，操作方便，制柱成功率高，所制备色谱柱具有柱效高、批间重现性好的优点。
摘要（英）：

The utility model relates to a controllable pressurization of capillary gas chromatography post or evacuating device for for pouring into into, the capillary waits to fill stationary liquid or evacuation, including the multi -ported valve, with steady flow valve that the multi -ported valve is connected, with two gas pressure governing valves that steady flow valve connects, respectively with two manometers that two gas pressure governing valves are connected, respectively with two flowmeters that two manometers are connected, respectively with two relief valves that two flowmeters are connected and respectively with two two pressure device that the relief valve is connected, the multi -ported valve is connected with gas cylinder or vacuum safety bottle, pressure device installs inside and remains to be filled the stationary liquid, the capillary stretches into treating in the pressure device is filled in the stationary liquid. This controllable pressurization of capillary gas chromatography post or evacuating device has safety, the high efficiency, the environmental protection, convenient operation, system post success rate is high, the preparative chromatography post have the post imitate high, criticize between the good advantage of repeatability.
