Features:

1, All functions are controlled by PC, so that can be flexible matching flame, graphite furnace. With the unique optical mechanical design,  the safe convenience flame system, the temperature control technology of graphite furnace ,the selectable deducting background technology, and more others handy features provided by workstations. All of this meeting your pursuing to result of automatic accurate determination.

2, Adopting the excellent design of Agilent Technologies in U.S, so the machine highly stability and long lifetime;

3, It’s little space occupation with minimum volume of its kind is 700x550x440mm,

4, To complete switchover within 10s between flame and graphite furnace.

5, The excellent graphite furnace auto sampling technology with high precision.

6, The flexible On-line dilution system can greatly simplify the operation of analysis and improve the analysis efficiency.

7, The stable and reliable graphite furnace atomic system make the temperature control more accurate by using PID technology.

8, The advanced and reliable safety protection system to protect the safety of operators in all-round.

9, By using highly sensitive flame sensor to avoid interference bring by outside light.

10, For more safety control to underpressure, air leakage, flameout and others exceptional conditions

11, The compact lifting table structure let users more  convenient to adjustment

12, Increase the working software of hydride generator

13, The software has add method store function, It’s save more time that the users can callout anytime after standard curve be stored , The graphite furnace atomic absorption increase 80 automatic sampler

Advantages:

 The Chinese unique Multimedia graphite furnace Visual System can monitor dynamic evolution of samples during drying, ashing, burning of inside the graphite tube, it’s convenient to observe the best place and depth of automatic sampler capillary syringe enter into graphite pipe, and the location of platform insert to the graphite tube. To ensure analytical precision and lifetime of graphite tube. To monitoring inside of graphite tube in real time by the CCD camera of installed on instrument cooperate with Altarsoft Video Capture, The capillary syringe and platform can be clearly display, to ensure the best place and parameter selection of automatic sampler capillary inject the samples. The analyst is easy to operation and ensure the high reliability of analyze.
