AI Technical Summary

Technical Problem

Existing liquid chromatography-mass spectrometry (LC-MS) sample racks have shortcomings in sample management, temperature control, and ease of operation, resulting in low detection efficiency, inaccurate results, and easy sample confusion.

Method used

A sample rack was designed, comprising a pull-out plate, a spare support plate, a heating chamber shell, and an electric heating tube. The sliding cooperation between the pull-out plate and the table allows for convenient sample loading and unloading. An insulated box and the heating chamber shell form a sealed cavity for precise temperature control, ensuring sample stability and zoned management.

Benefits of technology

It enables efficient zoning management and rapid sample handling, ensures temperature stability, reduces detection errors, and improves operational convenience and the reliability of test results.

Abstract

The utility model relates to the technical field of analytical chemistry detection, in particular to a liquid chromatograph-mass spectrometer sample holder for TDM detection, which comprises a support mechanism, the top of the support mechanism is provided with a sample placing box, and the top of the support mechanism is provided with a heat preservation mechanism; through the arrangement of the drawing plate, the standby supporting plate, the table plate and other parts, and through the sliding fit relation between the drawing plate and the table plate, the drawing plate can conveniently take and place a sample to be detected in the first positioning groove through horizontal sliding; meanwhile, the standby supporting plate is fixedly connected with the supporting side plate, so that the detected samples can be classified and stored. And the two parts are matched to form an ordered sample management system, so that the device can efficiently distinguish and quickly store and take samples in different detection states through a modular partition design, and the convenience of experimental operation and the flow standardization are remarkably improved.
