3 Lamps Three Channel AFS Atomic Fluorescence Spectrometer
Hydride generation system
Integrated reaction module, reaction system and gas-liquid separator integration, small dead volume, high degree of integration,
simple maintenance
High precision ten roller four channel peristaltic pump sampling and waste discharge system, constant pressure hydrogenation
chamber, less hydride loss, stable reaction;It can upgrade the two-mode sampling of continuous injection and intermittent
injection, taking into account two application scenarios of test accuracy and sample loss
Atomized system
Double layer quartz atomization furnace core, small liquid phase interference, stable flame, high atomization efficiency, small
memory effect, suitable for long-term use
Corrosion resistant heater wire, good acid resistance, long service life
High performance cyclone two-stage gas-liquid separator, high efficiency to remove liquid phase, reduce fluorescence quenching, no
need to add liquid, easy to use
The light path
Fully shielded short focal length 3 lamp position, 3 channel colorless astigmatism design, high efficiency of fluorescence
collection
Multichip combination stray light elimination system can avoid stray light entering the detector and reduce the light path
background
Pulse debugging constant-current driven self-identifying high performance hollow cathode lamp power supply, stable output energy,
high luminance, plug and play
Solar blind photomultiplier with high sensitivity, high signal-to-noise ratio and stable performance
The circuit system
High performance interchannel interference elimination system, interchannel interference ≤ 0.5%
16-bit high precision data acquisition circuit, shielded very low bias current preamplifier circuit, low signal bottom noise, high
data acquisition accuracy
