Description
Atomfair-ASF-739 Portable Atomic Fluorescence Spectrometer
I. Core Advantages of the Instrument
- Dual-channel power supply design: Compared with the traditional single-channel power supply mode, the dual-channel power supply significantly enhances the energy of the excitation light source, effectively improves the instrument detection sensitivity, and ensures accurate capture of trace elements.
- Integrated multi-functional reaction module: It highly integrates key functions such as hydrogenation reaction, gas-liquid separation and waste liquid discharge. The pressure self-balanced waste liquid discharge system does not require additional pump assistance, which greatly simplifies the instrument structure, reduces the probability of failure, and ensures stable and controllable reaction process.
- 3D orbital adjustment mechanism: Replacing the traditional two-dimensional adjustment mode, it supports three-dimensional adjustment (up & down, left & right, front & back) of the atomizer, with more convenient operation and more accurate positioning. It can quickly optimize the excitation effect and further improve the instrument sensitivity.
II. Basic Functional Configuration
- Supports single-channel detection and dual-channel simultaneous detection modes to meet the needs of different detection scenarios.
- Equipped with the functions of establishing single-point, two-point and multi-point standard curves, as well as correcting single-point and two-point standard curves to ensure the accuracy of detection data.
- Covers comprehensive injection mode control including continuous flow injection and traditional injection, suitable for various sample types.
- Real-time observation of the whole test process, supporting online adjustment of the three-dimensional parameters of the atomizer for timely optimization of test conditions.
- Optional fast intelligent automatic sampler to improve detection efficiency and reduce manual operation errors.
- Equipped with a user-friendly software interface that can recommend the optimal instrument test conditions; supports graphical display, playback, statistics and query of test data, as well as page saving, output, backup and printing of various graphics and data; the suspended measurement window design increases the number of displayable information such as fluorescence intensity and blank value.
- Built-in instrument self-test function and gas cut-off early warning protection system to fully guarantee the stable operation of the instrument and the safety of operators.
- Optional harmful element capture device in the detection tail gas, complying with environmental protection requirements.
- Seamless connection with liquid phase and online digestion modules to realize speciation analysis of As, Hg, Se and other elements.
