In general, sealed samplers are divided into three categories based on medium and function, namely gas sealed samplers, liquid sealed samplers, and online samplers
First, let's take a look at the gas sealed sampler. It is mainly used for collecting samples of gas or gas-liquid mixtures. The characteristics of this sealed sampler are fully sealed, and the samples will not come into contact with the outside world, ensuring the freshness of the samples. It is suitable for sampling various toxic, harmful, flammable, explosive and other gases, liquids, gas-liquid mixtures
Glass bottle sealed samplers are often used for collecting non-toxic and harmless samples in liquid media, mainly through a three-way ball valve for circulation and sampling control. The operation is simple and convenient, and the use of glass bottle samplers is more intuitive, making laboratory analysis simpler
Finally, there is a rocker plug sampler. It can adapt to sample collection of liquid media. When the sampler is shaken in, the top of the rocker is pressed against the stored sample. When shaken out, a new sample is introduced, and nitrogen is used to purge the outlet of the sampling valve to remove residual samples in the valve and needle. It is suitable for collecting representative samples in the cylinder slot and process pipeline“
