Description

Sample frame sampling device and sample analysis system

Technical Field

The utility model relates to a sample frame sampling device and sample analysis system, concretely relates to sample frame sampling device and sample analysis system that can access TLA.

Background

In order to access a TLA (fully automated pipeline track system), an analyzer interface scheme is generally required to be designed for current analyzers and the like. According to the sample suction mode of the analyzer, the interface scheme can be divided into an on-track sample suction mode and a sample rack sample suction mode.

Aiming at the sample sucking mode of the sample rack, the analyzer can be used for single-machine analysis or form a system with a TLA cascading mode. In order to connect the sample analysis system to the TLA, in the current interface scheme, the distance between the on-line sample introduction channel and the on-line return channel is small, so that the SDM cannot be directly butted with the sample mounting mechanism, a scheduling mechanism must be arranged between the SDM and the sample mounting mechanism, and the increase of the scheduling mechanism increases the total width (transverse) length between the whole SDM and the TLA, and the width direction of a laboratory needs to be enlarged, which is not favorable for the layout of the TLA.
