-
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
Long life (3 years) and high efficiency (70%) active and recycling mercury trap
Powerful function and upgrading capability
Adding PDI-10 UV digestion device and work station, and coupled with chromatographs realizes speciation analysis of As, Hg, and Se.- Adding WM-10 Ultra-trace Hg determination device to determine directly the ultra-trace Hg in water samples of surface water, sea water, tap water and source water, etc.
Adding VM-10 Gaseous Hg determination device to determine directly the ultra-trace Hg in gas sample of air, natural gas, laboratory and working environment, etc.- Two kinds of autosamplers available for fully automatic operation.
