Purpose and application ATDS-3420 automatic injection device for thermal desorption is a sample processing device, can be used with all imported and domestic gas chromatograph equipped . Applies to the following areas: 1, occupational safety, industrial hygiene, and environmental monitoring; 2, rapid identification of unknown atmosphere; 3, spice, flavor analysis; 4 accidents, toxic substances assessment (people when they can return safely to trouble spots); 5, chemical environment of perimeter security monitoring of the Treasury; 6 quality control testing, polymers, packaging industry; 7, solvent and drug purity assessment; 8, drugs and the Court sample residue analysis; 9, collected in the hospital patients ' exhaled gases, detection of volatile metabolites of drugs in the blood. principle
TDS-3430 Multifunction thermal desorption apparatus of a sample to the processing means , with the use of supporting gas chromatograph . It first specimen thermal desorption into the injection needle tube , and then the manual sampling injector and analyzed by gas chromatography . TDS-3430 multifunction thermal desorption apparatus : the desorption activation of processing furnace , the large syringes heating thermostat furnace , dual temperature controller and manual operation of four parts . TDS-3430 multifunction thermal desorption device has a number of characteristics :
Desorption activation treatment furnace and a large syringe heating thermostat furnace integrated design , a multi-purpose machine , greatly enhance the value for money of this device and operating costs ;
(2) the same sample can be repeated injection , to eliminate the adverse effects of injection or analysis misuse ;
3. Do TVOC Determination , the use inexpensive activated carbon adsorption tubes ;
Compared with domestic different types of thermal desorption instrument ( device) installed solutions straw easiest , and no dead volume operation ;
Especially suitable for chromatographic analysis are not familiar with the operation of the novice . technical indicators:
1. Desorption activation processing furnace
