optical spectrometer / benchtop / atomic fluorescence
AF-630A/640A
Vnation JSC

-
Type:
optical
-
Other characteristics:
benchtop, atomic fluorescence
Ultra trace level (ng/mL) determination of As, Sb, Bi, Zn, Cd, Hg,Ge, Sn, Pb, Se and Te.
Double channels / triple channels, two elements / three elements determination simultaneously.
Upgradable to atomic fluorescence speciation analyzer.
Especially suitable for geologic samples, simultaneous analysis of As, Sb&Bi (AF-630A).
Features:
Light Source System
Single-cathode or double-cathode hollow cathode lamp can be used as the light source.
Pulse power supply mode for higher stability and lower drift.
Main current and auxiliary current of double-cathode HCL are automatically matched by PC.
Optical System
Short focal length, non-dispersive, and light close optical system
Advanced gas-liquid separator, with higher signal-to-noise ratio
Comparable performance with Nafion drier;
Anti-foaming design, especially suitable for ion pair separation method;
Waste liquid auto drain design, no peristaltic pump is necessary.
Low temperature atomization technique
Argon-hydrogen flame auto ignition:
Stable temperature control system;
Very high stability atomization efficiency.
