Sample atomization

Atomizer:    Quartz tube furnace with automatic ignition of Ar-H2 , diffusion flame reduces interference

Carrier gaz: Argon

Protection gaz : Argon

Sample preparation and introduction:

Vaporizer / hydride generator (continous flow:

Continuous flow, peristaltic pump and /or syringe pump sequential injection system, high performance mixing section, gas-liquid separator for cold vapor mercury determinations and hydride generation. Determination of As, Se, Te, Bi, Sb, Sn, Pb, Ge, Zn, Cd, Hg

 

Sequential Injection:

Sequential injection, complete control of sample injection which significantly improves detection limits as well as increase reliability , eliminates drifting completely, allow sample volume to be adjusted within a big range, easy operation and allow on line dilution.

Peristaltic Pumps: a 6-channels pump with 2 adjustable pressure control clamps and programmable speed control

Syringe option: Two syringe pumps, one for the sample and one for the reagents. Allows software control of sample introduction

 

Optics:

Short focal length , non dispersive, integrated optical design

Dual Channel for sequential or simultaneous two element analysis, using computer controlled, modulated pulsed light source.

Light Source: Specially designed high intensity hollow Cathode Lamp with 2 channel independant power supply, providing improved sensitivity and lower detection limits.

Detector:

High quantum efficiancy , solar blind photo multiplier tube
