    Abstract: A sampling device and a gas curtain guide are disclosed. In one aspect, the sampling device includes a chamber body. The chamber body includes a sample inlet, located at a first end of the chamber body, configured for suction of a sample. The chamber body further includes a sample outlet, located adjacent to a second end opposite to the first end of the chamber body, configured to discharge the sample. The chamber body further includes a gas inflation inlet, in a wall of the chamber body, configured to introduce a swirl gas flow into the chamber body. The chamber body further includes a gas exhaust opening configured to discharge gas so as to, together with the gas inflation inlet, generate a tornado type gas flow in the chamber body, which moves spirally from the first end to the second end of the chamber body.

    Abstract: The present disclosure provides a High-Purity Germanium (HPGe) detector, comprising: a HPGe single crystal having an intrinsic region exposed surface; a first electrode and a second electrode connected to a first contact electrode and a second contact electrode of the HPGe single crystal respectively; and a conductive guard ring arranged in the intrinsic region exposed surface around the first electrode to separate the intrinsic region exposed surface into an inner region and an outer region. A leakage current derived from the intrinsic region exposed surface of the HPGe detector can be separated from the current of the HPGe detector by the conductive guard ring provided in the surface, thereby suppressing the interference of the surface leakage current.

    Abstract: A cryostat includes a room temperature vessel, a low temperature vessel, and a refrigeration mechanism. The room temperature vessel includes a room temperature tank, an outer neck tube and a sealing head. The low temperature vessel includes a low temperature tank, an inner neck tube and a liquefaction chamber. The liquefaction chamber corresponds to the first opening and passes through the first opening. The refrigeration mechanism includes a device panel and a refrigeration device. The device panel is disposed on the sealing head. The refrigeration device includes a body and a cold finger. The body is disposed at the device panel. The cold finger is connected with the body and extends into the liquefaction chamber.

    Abstract: A sample introduction device comprises a sampling unit, a gas suction pump, adsorption units, a piston cylinder and a desorption cylinder that comprises a desorption chamber, a carrier-gas inlet, a split/purge vent and an analyzer nozzle communicating with the desorption chamber. A heating film and a temperature sensor are provided on outer wall of the desorption cylinder. The piston cylinder above the desorption cylinder comprises two piston chambers, each of which is provided with the adsorption unit and in communication with the desorption chamber. The piston cylinder comprises a sample-gas inlet connected to the sampling unit and a gas-suction-pump orifice connected to the gas suction pump, each of which can communicate with both piston chambers. Each adsorption unit comprises an adsorption cylinder-like screen for holding adsorbents and a piston rod slidably mounted in the piston chamber. Each adsorption cylinder-like screen can simultaneously communicate with the sample-gas inlet and gas-suction-pump orifice.
