Abstract
The utility model provides a hydride generation system used for element speciation analysis. A condensing device is arranged outside a tube wall on an upper half section of a self-discharging type gas-liquid separator. The bottom of the self-discharging type gas-liquid separator is in a plane structure. The self-discharging type gas-liquid separator is arranged in the center of the top of a magnetic stirring device. A magnetic stirrer is installed on the bottom inside the self-discharging type gas-liquid separator. The magnetic stirrer is placed in the center of the magnetic field of the magnetic stirring device. According to the hydride generation system used for the element speciation analysis, when the magnetic stirring device is powered on, the magnetic stirrer is driven to rotate, so samples in the self-discharging type gas-liquid separator are fully stirred, and the reaction efficiency is close to 100%. The condensing device is arranged on the upper half section of the self-discharging type gas-liquid separator, so influences of water vapor on measurement are reduced, and analytical sensitivity is improved. Due to the fact that a waste liquid discharge outlet is added to the bottom of the self-discharging type gas-liquid separator, residual waste liquid and cleaning liquid can be completely drained from the gas-liquid separator.
