Sample weighing method for automatic industrial analysis instrument

Abstract

The invention discloses a method for weighing samples on automatic industrial analysis instruments. The steps are as follows: S1: placing all sample loading containers; S2: lowering the sample plate, and clearing the weighing balance; S3: filling the sample loading containers Add the sample into the sample, weigh it directly with a weighing balance to get the sample weight, and record it as the sample weight M 1 , the sample tray rises; S4: Take the sample container out of the weighing balance, and the absolute value of the negative weight value obtained on the weighing balance at this time is the weight of the sample container, which is recorded as M 0 ;S5: M obtained by weighing 0 and M 1 , to participate in the calculation of indicators. The invention has the advantages of simplifying steps, reducing working time, improving overall efficiency and the like.

Description

Technical field [0001] The present invention mainly relates to automated industrial analysis equipment, and particularly refers to a sample weighing method suitable for automated industrial analysis instruments. Background technique [0002] Automated industrial analysis equipment is gradually being used in many industries and fields to perform fully automatic, streamlined analysis or measurement operations on samples. In various automated industrial analysis equipment, in order to improve the efficiency of instrument analysis and testing, multiple sample access positions or sample trays with multiple samples are often set on the instrument, and the sample access position is changed or the sample tray is rotated to replace Testing samples avoids the problem of repeatedly loading and unloading and replacing samples when there are multiple sample testing tasks, so that multiple samples can be measured one by one. [0003] For the analytical instrument that measures the weight differ...

Problems solved by technology

In such a weighing system, the center of gravity of the placed crucible may change every time due to the accuracy error of the rotation of the selection plate or the rotation of the manipulator, and the difference in the lifting speed and direction during multiple weighings, which affects the balance of the weighing balance. torque resulting in weighing error

[0015] 3. Since in the weighing system, the final result needs to be rounded off for each weighing, redundant weighing times will increase the cumulative error caused by the rounding, which will affect the weighing accuracy
