This invention discloses a pressure-damage-free chromatograph and its operating method, comprising a chromatograph body and a line source block, and further including a pressure-free storage component and / or a pressure-free sealing component. The pressure-free storage component provides protection through storage and positioning. When in use, the line source block extends out of the storage frame, exposing its wiring terminals to ensure normal wiring operation. When not in use, it is stored back in the storage frame to prevent accidental contact or compression. The pressure-free sealing component provides protection through sealing. The line source block is placed in a protective frame, and a protective cover seals the wiring terminals of the line source block, thereby preventing accidental contact or compression damage. The arrangement of these two components has a positive impact on the normal use of the chromatograph and meets practical usage requirements. The pressure-damage-free chromatograph and its operating method provided by this invention can significantly improve the safety of the chromatograph and extend its service life.

This invention provides a low-temperature line-source evaporation deposition apparatus. The apparatus includes a crucible, a heat spreader, a heating wire, a heating electrode, a thermocouple, a water-cooling pipe, and a heat-insulating shielding layer. The heat spreader has a crucible groove milled into its inner side and a heating wire groove milled into its outer side, with a hole at the bottom. The crucible is placed in the crucible groove, the heating wire is embedded in the groove, and the thermocouple is inserted into the hole below the crucible. The water-cooling pipe is located outside the heat spreader, and the heat-insulating shielding layer is located outside the water-cooling pipe. A baffle is placed around the heat-insulating shielding layer to form a heat-insulating cavity. Using this low-temperature line-source evaporation deposition apparatus, heat is conducted between the heating wire, heat spreader, and crucible through contact, enabling rapid and uniform heating of the crucible and effectively reducing the loss of the evaporation material. The linear temperature field uniformity can be controlled within 0.1℃, thus ensuring uniform evaporation rate. The resulting film material has good thickness uniformity and density, significantly improving the efficiency of photovoltaic cells.
