Máy quang phổ huỳnh quang nguyên tử Drawell 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:
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
