Abstract: 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.

Abstract: Systems, devices, and methods are described herein for an auxiliary heat exchange system for use in scientific sampling. In one aspect, a heat exchange system may include at least one first conduit housed in an external casing, that is removably attachable to a heat/cooling system of a vehicle. Another conduit, such as a tracer tube, may be positioned proximate to the first conduit and housed in the external casing for at least a partial length of the first conduit. The tracer conduit may include a first end that is removably attachable to a gas collection device and a second end removably attachable to a measuring device. The first conduit may be configured to carry heated liquid from the heating/cooling system of the vehicle to maintain at least a threshold temperature of gas samples in the tracer conduit to prevent or reduce the formation of condensates in the tracer conduit.

Abstract: Systems, devices, and methods are described herein for a mobile scientific or measuring platform. In one aspect, a mobile scientific platform may include a vehicle having an electric energy source and a measuring device, such as a mass spectrometer, coupled to the electric energy source. An input line may be coupled to the measuring device and one or more sample collectors, for example, for obtaining gas samples. In some aspects, the input line may include a heating element configured to maintain a line temperature that is equal to or above the temperature of the samples collected, to reduce or prevent the formation of condensates in collected samples. In some aspects, the mobile scientific platform may run, or be switched to run, on electric, propone, compressed natural gas, or other similar fuel to enable the collection of gas samples free of (or having reduced levels of) vehicle caused contamination.
