Instrument main engine

* Two channels and two elements can be measured simultaneously.

* Optical path: dual-beam single-detector optical system, multi-light position design, full-channel dual-beam peer system design, with excellent channel consistency, anti-stray light influence, improve the accuracy and stability of the instrument.

* Light source system: hollow cathode lamp adopts new pulse modulation/constant current drive power supply mode.

* Hollow cathode lamp using coding technology, the instrument automatically identifies the hollow cathode lamp, and can monitor the working state and service life of the hollow cathode lamp

* Detection system: imported photomultiplier tube.

* Injection system: injection pump continuous flow injection device. (Sample blanks are introduced alternately to avoid cross contamination of samples and ensure the accuracy of measurement)

* Adopt new discontinuous flow no residual steam reaction system, reaction efficiency is higher

* The high efficiency gusher flow two-stage chemical gas-liquid reaction separation device, the chemical reaction is more complete, the gas-liquid separation effect is better, especially suitable for rock, ore, soil and other complex sample determination

* With carrier gas current stabilizing device, can not only eliminate the bubbles produced by potassium borohydride online, but also reduce the diffusion effect between reagents, improve the stability of the instrument

* Two-stage vapor-liquid separation device, the first stage chemical vapor phase gas liquid separation, two-stage water seal vapor-liquid separation device efficient water removal without manual waste

* Adopt new type gas circuit design, which can control the shutdown of gas source at any time, save the argon gas consumption, and reduce the operating cost of the instrument

* The circuit of the instrument adopts strong and weak current separation and a new high concentration module.

* Use closed quartz atomizer.

* The instrument adopts low temperature furnace atomizer.

* With external filter argon hydrogen flame real-time observation window, can directly observe the flame state in real time.

Technical index data processing system

* Can switch off line/on line at will

* Single/multiple Windows open at will

* Single/multi-database option

* Management sample correction to further improve measurement accuracy

* Using Windows98/2000/XP Chinese window operation software, can realize automatic system diagnosis, automatic sample measurement, standard curve method measurement, a variety of report formats
