DW-AFS-630A/640A Atomic Fluorescence Spectrometer

 Characteristics:

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

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

3.Upgradable to atomic fluorescence speciation analyzer.

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

Features:

1.Light Source System

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

3. Pulse power supply mode for higher stability and lower drift.

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

5. Optical System

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

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

8.Comparable performance with Nafion drier;

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

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

11.Low temperature atomization technique

12.Argon-hydrogen flame auto ignition;

13.Stable temperature control system;

14.Very high stability atomization efficiency.

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

16.Powerful function and upgrading capability

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

18.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.

19.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.

20.Two kinds of autosamplers available for fully automatic operation.
