Product Description

Laboratory Instrument/Atomic Absorption Spectrophotometer with High Sensitive Fpd/Aas for Analysis Equipment

4520A Automatic Flame/Graphite Furnace Atomic Absorption Spectrophotometer


All the functions of 4520A are operated by PC that can flexibly match with flame/graphite furnace. It has special optical mechanical design, safe and convenient flame system, advanced temperature controlling technique for graphite furnace, optional background correction technique and other functions supplied by workstation for the automatic and precise detection for users. 
1.The instrument has strong stability and long life. 
It has table performance by adopted the perfect design of American Aglient. 
2.The functions is complete with the functions of flame atomization and graphite furnace atomization. 
It can operates flame and graphite furnace atomization by the same system. The flame and graphite furnace do not need switching so that to avoid the complex working caused by switching and improve the analyzing efficiency.
3.The stable and reliable graphite furnace atomization system makes the temperature control more precise.
This instrument has the technique of high precision auto-injection and adds the 85 auto-injector. The temperature control is more precise by the PID technique. 
4.The use of the flame sensor with high sensitivity avoids the interference from outside light.
5.It is the unique visual system of graphite furnace in domestic. 
5.1 The unique visual system of graphite furnace can visually monitor the dynamic evolution of the injections during the drying, ashing and burning processes. It is convenient to observe the capillary injecting needle of the auto-injector entering into the best part and depth of the graphite furnace, and the position into the graphite furnace to confirm the analysis precision and the using life of the graphite furnace. Also, it is a perfect tool for train. 
5.2 Cooperated with the video capture software, the CCD installed in the instrument monitors the inside conditions of the graphite furnace at real time. The capillary injecting needle and the platform can be displayed clearly to confirm to select the best part and parameters for injecting. This process is convenient for the users to operate and confirms the high reliability of the analysis.

6. High analyzing efficiency
The flexible online dilution system greatly reduce the analyzing operation process, so as to improve the detection efficiency.
7. Advanced and reliable safety protection system.
It can protect the users' safety all-round and provides the safe and timely control for abnormal conditions, such as under pressure, gas leakage and flameout. 
8. More comprehensive software functions.
It is added the hydride generator working software with the function of method store that the user can store and tune out the standard curve at any time to solve the analyzing time. 
9.The shape design of the instrument is simple and convenient for operation.
Smaller than other instruments of the same type, the instrument dimensions is 700×550×440(mm),  which needs small lab area. It is convenient for the user to adjust the lifting platform with simple structure.
