Funzione

1. The sample transmission pipeline adopts high inert deactivation pipeline, no residue, no cross contamination, to ensure the repeatability and accuracy of sample injection;

2, controllo del programma informatico, le funzioni principali sono:

(1) Impostazione dei parametri del metodo, real-time display of working status and running time;

⑵ The analytical area, sampling valve and sample transmission tube are heated and controlled separately;

⑶ Set the analysis program and press the Run key to automatically complete the sample analysis;

⑷ Can be installed for normal temperature secondary desorption instrument or low temperature secondary desorption instrument according to user needs;

⑸ Avviare la GC, workstation di elaborazione dati cromatografici in modo sincrono, utilizzare anche un programma esterno per avviare il dispositivo;

3, this machine comes with the standard sample simulation sampling function, can be more convenient through the thermal desorption instrument production curve;

4, the use of high temperature six way valve, the highest use temperature can reach 240℃;

5, through time programming, automatic desorption, campionamento, backblow cleaning and other functions;

6, sample transfer tube and sampling valve have automatic backblowing function, to avoid the cross contamination of different samples;

7, in order to support the use of imported gas chromatograph more convenient and accurate, lo strumento è inoltre dotato di un'interfaccia speciale per vari strumenti importati, connessione facile;

8. The connection point of the six-way valve and the transmission pipeline is in the heating insulation box, without transmission cold point, to ensure the integrity of the sample;

9. The needle is easy to change, and can be connected to all types of GC injection ports at home and abroad;

10, integrated design, compact structure; Microcomputer control, all Chinese 7 inch LCD display, facile da usare.
