AUTOMATIC SAMPLE PREPARATION SYSTEM HAVING PARALLEL PROCESSING FUNCTION

摘要

An automatic sample preparation system having a parallel processing function comprises a primary treatment unit (1), a secondary treatment unit (2) and a tertiary treatment unit (3) for preparing samples. The primary treatment unit (1) performs a sample treatment on a material and respectively obtains total-moisture sub-samples and a first material to be sample-prepared that is used to be processed by the secondary treatment unit (2). The secondary treatment unit (2) performs the sample preparation treatment on the first material to be sample-prepared and respectively obtains a sample for back-checks and a second material to be sample-prepared that is used to be processed by the tertiary treatment unit (3). The tertiary treatment unit (3) performs the sample preparation treatment on the second material to be sample-prepared and obtains an analysis sample. The system is simple and compact, is easy and flexible to operate, allows sample preparation units to perform treatment in parallel, can prepare three types of samples having different specifications at the same time; and accordingly the system has a high automatic degree of sample preparation, lowers labor intensity and improves sample preparation efficiency.
