[0002] When characterizing the specific surface area and pore volume of a material, a physical adsorption instrument will measure some isotherm data points, and then use relevant mathematical calculation models to characterize the specific surface area and pore volume of the material. However, testing these isotherm data points takes a long time. The fastest physical adsorption instrument currently on the market takes more than 2 hours.

[0023] See also Figures 1 to 5In an embodiment of the present invention, a multi-module parallel measurement device includes six physical adsorption instrument test and analysis modules 3 that are communicatively connected to a computer 1 through a network switch 2. The physical adsorption instrument test and analysis module 3 includes a shell 4, both sides of which are fixedly connected to side panels 5, and adjacent side panels 5 of adjacent physical adsorption instrument test and analysis modules 3 are fixedly connected to each other.

[0024] By adopting the above solution, the utility model, when in use:

[0025] 1. Task Decomposition: First, break down the complex experiment to be measured into multiple modules or subtasks (for example, the physical adsorption instrument test and analysis of the specific surface area of ​​the material requires testing five data points between relative pressures of 0.05 and 0.3, and the pore volume requires testing a data point at 0.98 or 0.99. These six data points are considered six subtasks, and each physical adsorption instrument test and analysis module 3 is assigned a subtask, meaning each module tests one data point for each subtask). Each module or subtask is relatively independent and can be measured independently. The final measurement results can be combined to form the overall result through data aggregation.

[0026] 2. Design a measurement plan: Design a corresponding measurement plan for each module or subtask. The measurement plan should take into account the characteristics of the physical adsorption instrument test and analysis module 3 or subtask and select appropriate methods and parameters.

[0027] 3. Parallel measurement: Multiple physical adsorption instrument test analysis modules 3 or subtasks perform measurements in parallel. By using multi-module equipment for parallel measurement, the measurement time is significantly reduced and the measurement efficiency is improved.

[0028] 4. Result merging: After the parallel measurement is completed, the measurement results of each subtask are merged to obtain the overall measurement result. The method of result merging is determined according to the specific task.

[0029] 5. Result verification: Finally, the overall measurement results are verified to ensure their accuracy and reliability. Verification methods may include comparison with other measurement methods, repeated measurements, etc.

The threaded end of the countersunk screw 26 passes through the corresponding through hole 24 and is connected with the threaded hole 16.

[0031] By setting the U-shaped block 25, the two adjacent side panels 5 can be locked by utilizing the countersunk screw 26 in conjunction with the threaded hole 16 and the through hole 24, thereby achieving mutual fixation of two adjacent physical adsorption instrument test and analysis modules 3. The operation is simple and convenient, and it is easy for users to assemble it themselves.
