Product Description

Product Introduction
1. The dual channel atomic fluorescence spectrophotometer series reduces the excitation angle between the light source and PMT on the basis of the original model, increasing the received fluorescence signal intensity and reducing background interference, thereby improving instrument sensitivity
2. The front door of the instrument adopts a semi transparent and corrosion-resistant ABS magnetic suction structure, which avoids external air interference and allows for online observation of chemical reactions during the testing process
3. Adding a channel signal control module to the circuit ensures no inter channel interference even when there is a significant difference in the concentration of the two elements measured in the sample during dual channel simultaneous measurement. Especially suitable for testing departments with large sample sizes and dual channel simultaneous determination.
Performance characteristics
Instrument function
 1. Single channel and dual channel simultaneous detection function.
2. The function of establishing standard curves for single point, two-point, and multi-point.
3. The unique calibration function for single point and two-point standard curves.
4. The unique dual independent curve correction and dual independent dilution function.
5. Automatic dilution of high concentration samples function.
6. Unique comprehensive injection control functions such as continuous flow sample injection and intermittent sample injection.
7. Unique real-time observation and testing process, with online adjustment of atomization three-dimensional parameters function.
8. The unique pressure self balancing waste liquid discharge function does not require additional pump discharge.
9. Unique small background remove  function.
10. A user-friendly software interface, recommended best instrument testing conditions, graphical display and playback of test data, statistics and queries, and various functions such as saving, outputting, backing up, and printing various graphics and data pages. Suspended measurement window, increasing the amount of information that can be displayed (fluorescence intensity, blank value, etc.).
11. Instrument self check and gas cut-off warning protection function.
The unique seamless docking with liquid phase and online digestion units enables the morphological analysis of elements such as arsenic, mercury, and selenium.
Interference and elimination methods
(1) Fe Al. Mg. Ca. K. Na. Cu. Pb Li, Rb Cs Mn. W. Mo. V. Sr. Ti. Sn. Ba, Ti
Cd. Co. Ni, Cr Ge, Ga, In do not interfere with the measurement.
(2) Can form hydride element As Sb and Bi should not exceed 500ug/mL and generally do not interfere with the measurement.
(3) Au<5ug/mL, Ag<25ug/mL do not interfere with the determination.
(4) Au When elements such as Ag, Pt, and Pd interfere, sulfur can be added to eliminate the interference of precious metals, and reducing the concentration of KBH4 or adding iron salts can also alleviate the interference of these elements.
Product modules
Hydride generation system
Adopting a multifunctional reaction module, this module highly integrates functions such as hydrogenation reaction, gas-liquid separation, and waste liquid discharge. The large number of bubbles generated during the testing of inorganic arsenic has a significant impact on the test results. The multifunctional reaction module can effectively reduce bubbles, simplify pipelines, and reduce fault points. It can be directly inserted and removed for easy operation and maintenance of instruments.
Sample injection system
 AFS-680 adopts patented continuous flow injection technology and dual peristaltic pump injection, greatly improving testing efficiency, which is three times higher than traditional injection methods. Testing a sample three times only takes 30 seconds.
Application field
Atomic fluorescence spectrophotometer is widely used in teaching and research, health and epidemic prevention, medical clinical testing, drug testing, food hygiene testing, urban water supply and drainage testing, agricultural product testing, beverage testing, environmental monitoring, cosmetics testing, metallurgical sample testing, geological survey testing and other industries. Innovative software and hardware design ensures the accuracy, safety, and ease of use of sample analysis, and instrument maintenance is simple and convenient.
