1) Light Source System: Utilizes a specially crafted high-intensity hollow cathode lamp, employing a cluster pulse control method.
2) Optical System for Deducting Light Source Drift and Pulsation in Atomic Fluorescence Spectrometer: Short focal length lens for condensation, dispersion-free fully enclosed light-shielding dimming system.
3) Automatically capable of online dilution, automatic cleaning, single-standard automatic standard curve preparation (r>0.999 for repeated measurements to ensure slope value stability), high-concentration automatic dilution, automatic addition of reducing agents, masking agents, and automatic sample introduction system.
4) Gas-Liquid Separator: Equipped with a chemical vapor generation gas-liquid separation device, and a water seal separation device for removing water vapor. An online device for eliminating reduction bubbles in hydride generation method, and a hydride generation device capable of eliminating bubbles and borohydride solution bubbles during the hydrogenation reaction process.
5) High-efficiency new-type shielded quartz atomizer, utilizing mainstream low-temperature atomization technology, featuring a dual gas path design for carrier gas and shielding gas. The shielding gas forms a circular protective gas layer, protecting the stability of hydride gas combustion and shielding out other interfering gases. A trap for capturing harmful elements in the exhaust gas from hydride generation atomic fluorescence measurements, removing harmful gases such as mercury vapor, reducing physical harm to experimental operators.
6) Windows 10 or above operating system with Chinese and English software.
7) Supports 10 sample blanks and 10 management calibrations, with selective introduction of samples and blanks.
8) Detection Limit (DL): As, Sb, Bi, Se, Te, Sn, Pb, <0.01µg/L; Hg, Cd≤0.001µg/L; Ge≤0.05µg/L; Zn≤1.0µg/L. Measurement Precision: RSD≤1.0%
9) Equipped with an upgrade interface for the morphological analyzer system, capable of being upgraded to a morphological analyzer.
10) The built-in concealed real-time observation window for argon-hydrogen flame reduces the interference of external light on the internal optical path of the instrument, thereby enhancing the stability of the instrument.
11) The light source adjustment and fixation process is adopted, with the adjustment and solidification of the element-free lamp components at the factory, which allows for plug-and-play functionality, eliminating the need for users to manually or software-wise adjust the optimal position again.
12) A gas-source sequential flow injection system is employed, eliminating the need for a peristaltic pump design for sample introduction, cleaning, and waste disposal.
13) The injection pump does not directly contact the carrier liquid or reducing agent, and the medium it directly contacts is water, thus avoiding corrosion of the injection pump by the carrier liquid and reducing agent, extending its service life.
14) A rolling flow gas-liquid separator is used, where the sample and reducing agent are directly injected into the gas-liquid separator through a three-way connection, and magnetic stirring forms a rolling flow, enabling more thorough reaction between the sample and reducing agent.
