System Design                                                                                                                                                                       

Optical System

High light throughput Single Beam

Modes of Operation

Atomic Absorption and Atomic Emission

Monochromator

Czerny-Turner type with 2 focal lengths at 355.8 and 345.6nm, Automated wavelength and slit selection.

Wavelength Range

185-900 nm

Grating

Holo graphic grating with1800 lines

Wide range UV sensitive photomultiplier tube

Lamp

Automated 8-lamp turret with independent lamp power supply for each lamp.Two additional heating
circuits for preheating lamps.

Background Correction

Deuterium (D2) Background Correction and Smith- Hieftje (Self-absorption) Background Correction.

Flame System                                                                                                                                                                         

Burner-Nebulizer-System

Titanium 100mm and 50mm burner heads: 100mm burner head for air / acetylene operation, 50mm burner
head for both air/acetylene and nitrous oxide/acetylene operation. Adjustable nebulizer using all Platinum
/ Iridium capillary, PEEK Nozzle and fixed ceramic impact bead is supplied as standard. Automated burner
height setting for each element by software, using a motorized burner mount for vertical burner adjustment.
The optimization of the operating flame condition is also fully automatic and software controlled.

Spray Chamber

The PPS (Poly phenylene Sulfide) spraychamber is used for both aqueous and organic solution.

Gas Controls

Software controlled gas box allows the automatic setting of gas flows for each element.

Safety Functions

Interlocked safety system prevents selection of the nitrous oxide flame if the nitrus oxide burner is not
fitted. Sensor controls for protection to use the incorrect burner head and check the siphon system. In
case of pressure failure of fuel or oxidant gas, or power failure, safety interlocks will shut down the gases
automatically in the right order.

Hydride System (option)

The Hydride system is a continuous flow system for the determination of As, Se, Sb, Sn, Te, Bi and Hg at low
and sub microgram per liter (ppb) levels using an electrically heated quartz cell. For the determination of Hg,
the cold vapor technique is used. Gas flow and two peristaltic pumps for the supply of reagent, acid and sample
solutions are controlled by the software.

Autosampler for Flame (option)

Corrosion resistant 85 position sample tray. Standard preparation and sample dilution function is included.
