Taking crude benzene as an example, the medium pressure is atmospheric pressure, the medium temperature is room temperature, and the volume of the sampling bottle (glass) is 500ML.
IILiaoning closed samplerUsage method:
Preparation of samples: Prior to sampling, it is necessary to select appropriate sample containers and sample quantities based on the substance to be sampled and the purpose of the sampling. Generally speaking, the more samples there are, the more accurate the analysis results will be.
Connect the sample container: Connect the connecting tube of the sealed sampler to the selected sample container, ensuring a tight connection and no air leakage.
Open the sampling valve: Open the sampling valve of the sealed sampler to allow gas to enter the sample container from the sampling valve.
Adjust flow rate: Adjust the flow rate of the sealed sampler as needed to ensure that the sampling speed meets the requirements. Generally speaking, the sampling speed should be controlled within a certain range to ensure the accuracy and stability of the sampling.
Sampling time: Choose an appropriate sampling time based on the substance to be sampled and the purpose of the sampling. Generally speaking, the longer the sampling time, the more accurate the analysis results will be.
Close the sampling valve: After the sampling is completed, close the sampling valve of the sealed sampler to stop gas from entering the sample container.
Record sample information: Record information such as sampling time, location, sample quantity, sampling environment, as well as the usage of the closed sampler and the number of the sample container.
Transport samples: Transport sample containers to laboratories or analytical institutions for analysis.
3、 Other optional features
The above introduction shows that the liquid sealed sampler is a conventional type that collects media at room temperature and pressure. For different liquid media, the following functions can be added:
1. Heat tracing type: used for sampling low-temperature and easily condensable media
2. Cooling type: used for sampling high-temperature media. The cooler can be built inside the box or connected separately externally
3. Pressure reducing type: equipped with a pressure reducer, used for sampling high-pressure gaseous media to prevent overpressure damage to sampling equipment and fittings
4. Filter type: used for sampling impure media with high impurities
5. Fully automatic type: One click completion of sampling operation
4、 Installation of closed sampler
The side inlet and outlet flanges of the closed sampler can be connected to the on-site inlet and outlet flanges
