Urgently needed: Practical gas sampler design
Thread Content
Dear experts: The samplers I have are not working well, and I would like to modify them. Please help by providing information on practical samplers that could be used. Thank you! !
Tell everyone about the samples you want to collect; otherwise, they won’t be able to help you.
This thing is great; study it well
Do you mean the gas sampling probe, or a part of the sampling device that is connected to the apparatus? Also, please provide details such as the type of sample, as well as pressure and temperature. There are chimneys, an atmosphere, as well as devices that operate at normal temperature under pressure or at high temperatures.
What I need is a more practical version of samplers for the low-pressure gas from the hydrogenation unit and the acidic gases from the top of the distillation tower. Thank you! !
Could you use vacuum extraction? Create a buffer tank in front of the vacuum tube, and this buffer tank should be equipped with a vent; sampling should be carried out at the buffer tank itself
Which products are hydrogenated? The methods for hydrogenation sampling vary depending on the product. For example, the sampling methods for fatty acid hydrogenation and the hydrogenation of other hydrocarbon gases are different.
I wonder what gas you’re collecting? Sampling from the cylinder is required when under high pressure. General sampling can be done using a bulb sampler or a quartz sampler. You didn’t mention the specific gas, so it’s hard to say. Please be more detailed~~
Go to other organizations and see how they do it
I am in the business of selling American Sentry sealed samplers; if anyone needs them, they can contact me for more information.
Common sampling devices include gas samplers, liquid samplers, and liquefied gas samplers. Gases are generally sampled using cylinders, which are connected via quick connectors. The sample is allowed to circulate within the cylinder for about a minute to ensure that the sample collected is representative. Then close the valve below the cylinder to maintain pressure, ensuring that the pressure of the sample collected is the same as that of the system; next, close the valve above the cylinder and open the gas release valve on the circuit to relieve pressure. After that, remove the cylinder and connect the male and female quick connectors (the pressure to be withstood increases from 20 kilograms to 300 kilograms). The gas cylinder can then be taken to the laboratory for analysis. It operates using a multi-channel single valve, offering simple operation, as well as safety and leak-free performance.
