Instrument Introduction:
AF-7500 Atomic Fluorescence Spectrometer AFSOur company has independently developed a new generation of atomic fluorescence spectrophotometer based on our own technological advantages. The instrument integrates the achievements of modern technology, computers, and optoelectronic technology, providing users with a simple, efficient, safe, and reliable analytical method.
This instrument has an extremely low detection limit and a wide linear range. Several key technical indicators have reached the current level abroad.

AF-7500 Atomic Fluorescence Spectrometer AFSApplication scope:
This instrument has a wide range of applications, including the detection of trace and ultra trace elements in food hygiene, urban water supply and drainage, environmental protection, agriculture, metallurgy, cosmetics, medicine, geology, commercial inspection, and other fields.
For example:
Analysis of food hygiene samples
Fishery and seawater sample testing
Environmental sample testing
Metallurgical sample testing
Urban water supply and drainage testing
Clinical laboratory tests and drug testing
Analysis and testing of agricultural products
Geological survey and mineral exploration applications, etc

AF-7500Main features:
1. Can measure multiple elements and simultaneously measure dual elements
Suitable for trace and ultra trace analysis of eleven elements including As, Sb, Hg, Se, Pb, Bi, Sn, Ge, Te, Cd, Zn, etc.
2. The efficiency of using the instrument has doubled
Due to the organic combination of the eight way injection valve and peristaltic pump (No.: ZL.2）， Realized continuous flow, intermittent injection, dual channel alternating injection, and alternating analysis.
At the same time as cleaning and sample injection, the other can be analyzed synchronously without cross contamination.
3. Infrared control, membrane separation gas-liquid separation system
Infrared control, membrane separation gas-liquid separation system (No.:) X) The application of this technology enables waste liquid to be discharged without the need for a pump, resulting in more thorough gas-liquid separation and truly achieving colorless flames. The noise level has been significantly reduced, the detection limit has been greatly improved, and the linear range has been expanded
4. Low temperature automatic ignition of argon and hydrogen flames
Increase sensitivity several times and reduce the "memory" effect
5. General power supply for high-strength hollow cathode lamps and special hollow cathode lamps
Providing convenience for users, they can replace the light source at any time according to their needs.
6. Far infrared heating atomizer
Equipped with advanced far-infrared thermal atomizers, the instrument heats up quickly, maintains high temperature accuracy, and has a long service life.
7. Automatic pneumatic control
This instrument adopts a large number of advanced circuit control systems, which enable automatic control and protection of the gas circuit, ensuring analysis safety.
8. Safe and reliable
Due to the use of strong anti-corrosion materials in the liquid circuit system, the instrument is safer and more reliable to use
9. Low cost analysis
Significant reduction in the consumption of reagents, samples, and argon gas
10. Computer System Analysis Automation
The AF-7500 Windows application automates the analysis process. Users can use this program to implement functions such as sampling, spectrum display machine post-processing, sample table generation, calculation results, and printing reports. The computer system adopts dual channel analysis and can control various states of the instrument according to user set parameters, implementing technical actions including automatic ignition, preheating, and segmented heating.
11. Compact instrument size
Due to the extensive use of optoelectronic technology, the overall volume of the instrument is reduced by half compared to similar domestic products, making it particularly suitable for places with high requirements for instrument space, such as ships.
12. Automatic sampler
130 bit large capacity sample rack, with simple structure, accurate and reliable operation, small size, light weight, easy connection with the host, and quick switching between manual and automatic states.
