Patent attributes
Systems, devices, and methods are described herein for a vapor or gas sampling device. In one aspect, the described collector may include an outer tube having first and second ends, with the hollow tube forming a plurality of perforations proximate to the first end. In some examples, the perforations may prevent the passing of detritus or environmental contaminants through the perforations. The collector may also include inner tube having a first end and a second end, with the hollow tube forming a plurality of perforations proximate to the second end, which is opposite the first end of the outer tube. The inner tube may be positioned or affixed at least partially inside of the outer tube. The perforations on the inner tube may be located towards the second end when relative to the perforations on the outer tube, such that the perforations of the two tubes do not overlap.
