Instrument Features
Flame System
1,Pure Ti atomizing chamber and burner
Prevent acid gas corrosion effectively and maximize service life
2,Efficient glass nebulizer
Efficient glass nebulizer with higher nebulization efficiency, easy to maintain and replace
3,Mass flow controller makes the flow of C2H2 controllable
Control C2H2 flow adjustable, monitoring the flow dynamically, ensuring it to be convenient and safe.
4,Multiple safety protection measures, ensuring the reliability of the sample analysis
(1)C2H2 leaking preventive measure
(2)C2H2 pressure monitoring
(3)Air pressure monitoring
(4)Burner monitoring
(5)Flaming burning monitoring
(6)Water seal monitoring
Graphite Furnace System
1,Internal power supply
The power supply of graphite furnace and host machine are incorporated in one instrument, which makes it more compact, shortens cable length, reduces the electromagnetic interference of graphite furnace power supply and improves heating efficiency of graphite tube.
2,High temperature control precision, quick temperature rise
Large power transformer, micro resistance cable and light control heating mode are used, combined with software and hardware temperature calibration systems, ensuring ±1% control precision under high temperature
3,Multiple safety protection measures, ensuring the reliability of the sample analysis
1)Cooling water flow monitoring
2)Carrier gas pressure monitoring
3)Graphite tube temperature monitoring
4)Graphite furnace temperature monitoring
4,Carrier gas flow auto-control
The internal and external gas of graphite furnace are automatically controlled by computer based on software heating procedures.
