公司介紹 主營產(chǎn)品

Welcome To Our Company
Founded in 1998 , we are a well established and professional supplier of instruments and equipments.

We enjoy good relations with excellent partners in North America ,European Union and Japan .Our principal products include: HTA of Italy, Z-nose of U.S.A, and TEKNOKROMA of Spain and so on.

In the field of chemical analysis ,especially in chromatography, we have sufficient supplies of instruments which are readily available. We ensure the quality of every instrument sold by us, in the meantime, offer satisfactory customer service.

In case of any problem with the instrument, we guarantee a response in 24 hours during workday.

With commitment to credit, we have obtained a large share of Chinese market ,at the same time, won the support and trust from our clients.

Dedicated to the mission of helping our customers spend money in a wiser way and utilize instrument more efficiently, we will unswervingly continue along the path of pushing Chinese instrumental industry to conform to international standards..

features:
. phase difference corrected monochromator, provide optimized optical path for entire wavelength.
. built-in 6 lamp turret, with 2 lamps (operation lamp and preparation lamp) simultaneously lightening.
. equipped with innovative and unique deuterium background correction (patent pending) for entire wavelength range.
. combustion gas cooling burner head is innovated newly and is applying patent. this technique could reduce much heating balancing time at the burner head.
. high safety air-acetylene flame facilitates 35 common elements analyzed at low operation cost.
. genius database system allows you to access index and abstracts of large amount of chinese and english literature.

complete automation on
. alignment and fine adjustment in hollow cathode lamp position.
. wavelength scan control and peak search and slit width se-lection.
. optimization of photomultiplier gain.
. energy balance between deuterium lamp and hollow cathode lamp.
. flame ignition (on/ off) as well as acetylene-o2 gas flow rate setting to optimize combustion ratio.
. optimization of analytical conditions for se-lected element simply by a mouse-click while six elements can downloaded simultaneously.

high safety
. fully automated gas control and integrated safety check yield the safest flame aa system available today.
. incorporated with air pressure sensor, acetylene gas flow will be cut in case of accident.
. combination of safety-designed burner head, special drainage system and pressurized valve control spray chamber.
. with presence of high pressure gas leakage check, it ensures automatic disconnection of gas lines in case of acetylene build up accidentally.
