Fixed Volume Liquid Sampler定容液体进样器
定容闭环液体进样器，目的是提供一个固定的量样本过程压力或流量独立，同时保持从工艺流和管道压力隔离操作
Fixed Volume Liquid Sampler
The Fixed Volume Closed Loop Liquid Sampler is designed to provide a fixed volume sample independent of process pressure or flow rates, while keeping the operator isolated from the process stream and line pressure.
This simplified, one-valve design allows for volume accuracy while obtaining a representative, emission-free sample safely. A pre-measured volume of sample is isolated and moved to a sample vial with a carrier gas. This system is a true dead volume sampler, as it and the sample vial are fully purged during the sample cycle, providing an inert atmosphere prior to each sample. The panel mounting allows for easy pipe, wall, or flange mounting.
The Fixed Volume Closed Loop Liquid Sampler can be designed to work automatically as a multi-vial sampler or as a composite sampler.
