metal analysis atomic fluorescence spectrometer device for laboratory

Atomic Fluorescence Spectrometer

DW-AFS-630A/640A

l Ultra trace level (ng/mL) determination of As, Sb, Bi, Zn, Cd, Hg, Ge, Sn, Pb, Se and Te.

l Double channels / triple channels, two elements / three elements determination simultaneously.

l Upgradable to atomic fluorescence speciation analyzer.

l Especially suitable for geologic samples, simultaneous analysis of As, Sb & Bi (AF-630A).

Features:

l Light Source System

 lSingle-cathode or double-cathode hollow cathode lamp can be used as the light source.

 lPulse power supply mode for higher stability and lower drift.

lMain current and auxiliary current of double-cathode HCL are automatically matched by PC.

lOptical System

l Short focal length, non-dispersive, and light close optical system

l Advanced gas-liquid separator, with higher signal-to-noise ratio

l Comparable performance with Nafion drier;

l Anti-foaming design, especially suitable for ion pair separation method;

l Waste liquid auto drain design, no peristaltic pump is necessary.

l Low temperature atomization technique

l Argon-hydrogen flame auto ignition;

l Stable temperature control system;

l Very high stability atomization efficiency.

l Long life (3 years) and high efficiency (70%) active and recycling mercury trap

l Powerful function and upgrading capability

l Adding PDI-10 UV digestion device and work station, and coupled with chromatographs realizes speciation analysis of As, Hg, and Se.

l 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.

l 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.

l Two kinds of autosamplers available for fully automatic operation.
