Abstract:In the process of analyzing and testing geochemical exploration samples, weighting sample is a single repetitive task with large workload and labor intensity. There are some problems in weighing samples in the laboratory, for example, cross contamination and accuracy of weighing samples is difficult to verify in time, easy to make mistakes, high labor costs and labor intensity and so on. From the view of technical methods and quality management, labor cost management, research and development of expected output and expected returns, social benefits and so on, the necessity of developing and using an automatic quantitative weighing device during analyzing and testing geochemical exploration samples has been analyzed, the importance of realizing automation in the whole process and promoting the overall progress of science and technology in the whole industry have been introduced as well.
