Introduction
The AF-7500 Atomic Fluorescence Photometer combines the latest achievements of modern technology, computer and photoelectric technology, and provides a simple, efficient, safe and reliable analysis method for the majority of users.
This instrument has a very low detection limit and a very wide linear range. Many major technical indicators have reached the leading level abroad.
Application range:
This instrument has a wide range of applications, including: food hygiene, urban water supply and drainage, environmental protection, agriculture, metallurgy, cosmetics, medicine, geology, commodity inspection and other trace and ultra-trace elements.
E.g:
Analysis of food hygiene samples
Fisheries and seawater samples testing
Environmental sample testing
Metallurgical sample testing
Urban water supply and drainage testing
Clinical testing and drug testing
Agricultural product analysis and testing
Geological survey and prospecting applications, etc. Features
1. Multiple elements can be determined, and dual elements can be determined simultaneously
It is suitable for the trace and ultra-trace analysis of eleven elements such as As, Sb, Hg, Se, Pb, Bi, Sn, Ge, Te, Cd, and Zn.
2. The working efficiency of the instrument is doubled
Due to the organic combination of the eight-way sampling valve and the peristaltic pump (patent number: ZL200620012910.2), continuous flow, intermittent sampling, dual-channel alternate sampling and alternate analysis are realized.
At the same time of cleaning and sampling, the other can be analyzed simultaneously without cross contamination.
3. The first infrared control, membrane separation type gas-liquid separation system
Infrared control, the application of membrane separation gas-liquid separation system (patent number: 200720104068.X), so that the waste liquid does not need to be discharged through the pump, the gas-liquid separation is more thorough, and the colorless flame is truly realized. The noise level is greatly reduced, the detection limit is greatly improved, and the linear range is expanded
4. Automatically ignite argon and hydrogen flame at low temperature
Increases the sensitivity several times, the "memory" effect is smaller
5. High-intensity hollow cathode lamp, special hollow cathode lamp universal power supply
Provides convenience for users, users can change the light source at any time as needed.
6. Far infrared heating atomizer
The advanced far-infrared thermal atomizer is used, the instrument heats up quickly, the constant temperature precision is high, and the service life is long.
7. Automatic pneumatic control
This instrument comprehensively adopts a large number of advanced circuit control systems, so that the gas circuit can be automatically controlled and automatically protected to ensure the safety of analysis.
8. Safe and reliable
Because the hydraulic system is made of strong anti-corrosion materials, the instrument is more safe and reliable in use
9. Low analysis cost
The consumption of reagents, samples and argon is greatly reduced
10. Computer Department Analysis Automation
The AF-7500 Windows application automates the analysis process. Users can use this program to realize functions such as sampling, post-processing of spectrogram display, 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 the parameters set by the user, and implement technical actions including automatic ignition, preheating, and sectional heating.
11. The instrument is compact
Due to the use of a large number of the latest photoelectric technology, the overall volume of the instrument is reduced by 1/2 compared with similar domestic products, and it is especially suitable for places with high requirements for instrument space, such as ships.
12. Autosampler
130-bit large-capacity sample rack, simple structure, accurate and reliable action, small size, light weight, simple connection with the host, manual and automatic state rapid switching.
The AF-7500 dual-channel hydride-atomic fluorescence photometer combines the latest achievements of current modern technology, computer, and photoelectric technology, and provides a simple, efficient, safe, and reliable analysis method for the majority of users. The AF-7500 dual-channel hydride-atomic fluorescence photometer has a very low detection limit and a very wide linear range. Many major technical indicators have reached the leading level abroad.
