Optics:
Double Beam with background correction and flame emission capability. Asymmetric modulation with 2:1 sample-to-reference ratio for noise reduction.
Monochromator:
Ebert-Fastie design with 333 mm focal length and 175–900 nm wavelength range. 1,800 line/mm grating, with dual blazed profile and linear reciprocal dispersion of 1.6. Automatic wavelength selection and peaking. Continuously adjustable slits with 0.1 to 2 nm spectral bandwidth. Reduced height available with all slit widths. Automatic setting of slit width and height. Automatic wavelength scanning.
Detector:
Photomultiplier tube detector with full wavelength range 175-900 nm
Lamp Turret:
Eight Lamp Turret with automatic lamp selection, automatic optimization in two planes for maximum light throughput. Automatic multi-element operation, with the next lamp in sequence automatically warmed up, compatible with standard hollow cathode lamps.
 Hollow Cathode Lamps:
Unique Dual Lamp Pivot Chasis Design, holds two standard hollow cathode lamps. Simultaneous power supply allows warm up of lamp while the other is in use. Optional 1 Super Lamp power supply also available.
 Background Correction:
Hyper-Pulse background corrector takes 200 (50 Hz) or 240 (60 Hz) sample readings per second for correction of fast background peaks. With approximately 1 ms between pulses and interpolation between measurements, best possible accuracy is assured. High intensity deuterium arc lamp provides 175–425 nm correction range. Corrects to 2.5 total absorbance.
 Programmable Flame Control:
Automatic setting of flame type and gas flows. Programmed ignition and shut down procedures. Automatic change of flame condition during automatic multi-element operation. Separate fuel and oxidant flow. Push-button ignition. Interlocks monitor burner type, liquid trap level. Ignition is prevented if a fault is detected. Interlocks prevent ignition with nitrous-oxide flame or changeover to nitrous-oxide flame with air-acetylene burner.
Flame Atomization System:
Premix design with solid polypropylene mixing chamber. All-titanium burner construction. Nebulizer has platinum-iridium capillary and titanium venturi. Adjustable sample uptake rate. Inert impact bead. Liquid trap with liquid level interlock.
System 5000 Fully Automated Graphite Furnace System:
System 5000 graphite furnace is a complete graphite furnace system which includes the PAL Autosampler for rapid and accurate analysis and power supply and workhead. The entire system is controlled by the SavantAA software. Almost 50 elements can be determined in ppb concentrations. Variable injection volume from 1 uL to 100 uL in 1 uL increments. Temperature program up to 3000C even for the most complex sample.
Safety Measures for Graphite Furnace:
The Graphite Furnace is permanently connected to power supply by umbilical cord carrying gas,      cooling water, and electrical supplies. Computer controlled maximum heating rate of 2000C/sec. Temperature controller monitors current and voltage and uses power feedback to provide accurate control over the full temperature range Interlocked to inert gas pressures, and corrects for changing in cooling water temperature.
Performance Guarantee:
Guaranteed best precision (5 ppm Cu gives <0.45% RSD) and
Guaranteed best sensitivity (5 ppm Cu gives >0.8 Abs) on the same measurement.
