Ancillary products

Atomic absorption spectrophotometer host, flame atomization system, graphite furnace atomization system, 85 bit automatic sampler.

Performance features

◆The instrument has strong stability and long service life

Using the excellent design of Agilent technology, the performance of the instrument is more stable.

◆ Complete function, at the same time with flame atomization and graphite furnace atomization function

(1) The same host can realize flame, graphite furnace and other different ways, within 10 seconds to complete the switch;

(2) The graphite furnace and flame do not need mechanical switching, which can avoid cumbersome work such as light path recalibration caused by switching, and improve the analysis efficiency;

(3) The use of high sensitivity flame sensor, eliminate the interference of external light;

(4) The flexible on-line dilution system can greatly reduce the analytical operation and improve the detection efficiency.

◆Stable and reliable graphite furnace atomization system, more accurate temperature control

(1) PID technology is adopted to make the temperature control more accurate;

(2) At the same time, it has high precision automatic sampling technology, adding 85 bit automatic sampler.

◆Domestic unique graphite furnace visual system

Domestic unique multimedia graphite furnace visual system can visually monitor dry inside the graphite tube, ashing, burn the sample liquid in the process of dynamic evolution, easily observe automatic sampler capillary injector needle into the graphite tube in the best position and depth, and platform in graphite tube insertion position, ensure the analysis accuracy and life of the graphite tube, is also a perfect training tool.

CCD camera installed in the instrument with video capture software to implement real-time monitoring of the graphite tube inside, capillary injection needle and platform can be clearly displayed, to ensure that the automatic sampler capillary injection test liquid of the best position and the best parameter selection, convenient for the operation of analysts, and to ensure the reliability of analysis.

◆ Advanced and reliable security protection system

Fully protect the safety of operators, implement safe and timely control of abnormal conditions, such as insufficient pressure, leakage, flout control;

◆ More comprehensive software functions

(1) Increase the working software of hydride generator method;

(2) Add method storage function to the software. Users can call up the standard curve at any time after storing it, which can save the analysis time.

◆ Simple shape design, more convenient operation

(1) The same kind of instrument has the smallest volume (700×550×440mm), occupying small laboratory space;

(2) The simple lifting platform structure makes it more convenient for users to adjust.
