Sampling of the components in nitrogen and hydrogen pipelines is required; what kind of sampler should be used, with a maximum pressure of 1 MPa, and it is also desired to be able to use it at atmospheric pressure...

What kind of sampler should be used for analyzing these components? The maximum pressure is 1 MPa, but sampling at atmospheric pressure is also desired; additionally, how should the sampling points be designed?
A regular instrument sampling valve will do; a bladder can be used, or a dedicated sampling bag (aluminum foil sampling bag, maximum pressure of 3 Kpa, volume of 5 L) can also be used
