Dual channel fully automatic one-time thermal desorption instrument

I. Overview

HLTD-A1seriesDual channel fully automatic one-time thermal desorption instrumentIt is a fully automatic one-time thermal desorption instrument that can simultaneously desorb two sample tubes. Realize dual channel sample tubes through detachment/A series of fully automated operations including extraction, pre concentration, and injection into GC or GC-MSDual channel injection has improved experimental efficiency and has the advantages of high work efficiency and cost-effectiveness compared to traditional thermal desorption.
