The present invention relates to a test system and method capable of simultaneously carrying out a high-throughput test of mechanical properties for miniature specimens. The system comprises one workstation () and a plurality of specimen test modules () installed horizontally or vertically on a workbench (), wherein the workstation () comprises an operation interface, a data processing unit and a load output unit; each specimen test module () comprises a drive unit (), an interchangeable clamp unit (), a displacement sensor (), and a load sensor (); the workstation () controls the drive unit () of the specimen test module () and receives detection data of the displacement sensor () and the load sensor (); each specimen test module () optionally performs mechanical property testing independently; and the workstation () controls simultaneously started testing of a plurality of specimens (). The present invention can achieve tensile, bending, compression bending, stress-rupture, relaxation, and fatigue strength tests on a plurality of specimens at the same time.

System and method for high-throughput test of mechanical properties of miniature specimens

A pulse heating&#x2014;time of flight mass spectrometric gas elements analyzer, which involves the chemical analysis field of inorganic materials, and comprises of a pulse heating electrode furnace, a sample charging system, a purification device, a time-of-flight mass spectrometer, a signal acquisition and data processing system, and an automatic control system. Said electrode furnace and sample charging system are united as one via upper/lower electrodes and pneumatic cylinders, to form a closed hearth. Said electrode furnace, purification device and time-of-flight mass spectrometer are interconnected through the gas pipelines: the purified inert carrier gas comes into the hearth from its top, carrying out the gas components released from sample fusion, and upon re-purification, comes into the time-of-flight mass spectrometer; said signal acquisition and data processing system is connected to the detector of the said mass spectrometer via signal cables, and on the basis of computation by the data processing module of the relevant computer software, outputs the mass percentages of O, N, H and Ar in the sample. The lower limit of detection can be below 0.01 ppm to 0.1 ppm, and no less than three elements can be measured simultaneously in one analysis cycle.
