Question: How to take samples of powdered materials transported by air
Thread Content
Dear experts, I am working on a pilot project that involves using air compressors to transport powdered materials. Every time I take samples, dust is generated everywhere. Do you have any good methods that allow for easy sampling while avoiding dust? Thank you
If the pressure permits, a branch can be created by opening a hole in the pipe, a valve can be installed at the base of the main pipe, and a filter tank can be connected to the atmosphere to achieve this. For greater accuracy, two filtration tanks can be set up: one for replacement and one for measurement and analysis. For reference.
This idea is good. By a filtration tank, I understand it to be a small dust collector, right? The gas is discharged directly
Found a vacuum sampling device on the forum; it’s currently under trial use. Thank you
This is easy to implement; first, a branch is taken from the pipeline as a sampling port. Then sampling is done using stainless steel or glass bottles.
