| description | The utility model relates to a volatile organic compound concentration device, which comprises a water removal trap, a packed column trapping trap and a capillary column focusing trap, the packed column trapping trap is connected with the water removal trap, the capillary column focusing trap is connected with the packed column trapping trap, the temperature of the water removal trap is gradually reduced along the flowing direction of volatile organic compounds, and/or the inner diameter of the water removal trap is gradually reduced. By changing the temperature of each part of the water removal trap and/or the size of the water removal trap, the water removal trap can be prevented from being blocked due to freezing, the sampling volume of a high-humidity sample can be increased, the water removal rate can be increased, and the accuracy and efficiency of concentration analysis can be improved.
本实用新型涉及一种挥发性有机物浓缩装置，其包括除水阱、填充柱捕集阱和毛细柱聚焦阱，填充柱捕集阱与除水阱连接，毛细柱聚焦阱与填充柱捕集阱连接，沿挥发性有机物的流动方向，除水阱的温度逐渐降低，和/或除水阱的内径逐渐降低。通过改变除水阱各处 |
