Abstract

The invention relates to the technical field of volatile organic compound detection and discloses an automatic sample injector for a full-automatic thermal desorption instrument, a working method of the automatic sample injector and the full-automatic thermal desorption instrument. On one hand, a Z-axis assembly, an X-axis assembly and a Y-axis assembly are arranged; an adsorption tube grabbing and sample feeding action and an adsorption tube putting-back action can be carried out in an area above a tray assembly; on the other hand, by arranging a cross beam assembly, a cover taking assembly,a loading assembly and a valve terminal assembly, complete sample feeding and discharging actions such as transferring, cover taking, loading, unloading, cover covering and returning can be sequentially carried out on the adsorption tube from which the sample is conveyed, so that the full-automatic thermal desorption instrument is particularly suitable for the full-automatic thermal desorption instrument, the manual workload is greatly reduced, and time and labor are saved. In addition, the automatic sample injector further has the advantages of being convenient to load/unload, high in grabbing success rate, capable of automatically detecting errors, simple in structure, easy to achieve and the like, and actual application and popularization are facilitated.

Description

technical field [0001] The invention belongs to the technical field of detection of volatile organic compounds, and the industries involved include environmental monitoring and occupational hygiene, etc., and specifically relates to an automatic sampler for a fully automatic thermal desorption instrument and its working method and a fully automatic thermal desorption instrument . Background technique [0002] The thermal desorption method is mainly used for the analysis of VOCs (Volatile Organic Compounds, volatile organic compounds, which refer to organic compounds with a saturated vapor pressure greater than 133.32Pa at room temperature, a boiling point below 50-260°C at a standard atmospheric pressure of 101.3kPa, and an initial boiling point equal to 250°C. compound, or any volatile organic solid or liquid at normal temperature and pressure), refers to the use of solid-phase adsorbent at normal temperature or low temperature to adsorb, fix, and enrich the analyte in the ...
