AAnalyst 600 和 AAnalyst 800原子吸收光谱指标

系统设计

AAnalyst™ 600 和 AAnalyst 800是第一台全集成的台式设计的原子吸收光谱仪，包括酥油的光谱和原子化部件在一台仪器中。 

Optical system

Front-surfaced, reflecting optics with protective coating. Optical system sealed within protective cover.

AAnalyst 800 Real-time double-beam optical system (single-beam for Zeeman furnace operation).

AAnalyst 600 Single-beam optical system.

Monochromator Littrow design with motorized drive for automatic wavelength selection and peaking.

Wavelength range波长范围: 190-900 nm

Diffraction grating: 1800 lines/mm blazed at 236 nm and 597 nm

Grating area: 64 x 72 mm

Reciprocal linear dispersion: 1.6 nm/mm (nominal)

Focal length: 267 mm

Spectral bandwidths: 0.2, 0.7 and 2.0 nm, dual height (AAnalyst 800 only);

motorized slit drive for automatic slit selection

Detector Wide-range segmented solid-state detector, including a built-in low-noise CMOS charge amplifier array.

Automatic 8-lamp holder with built-in power supplies for hollow cathode and electrodeless discharge

Lamp Selection lamps. Computer-controlled lamp selection and alignment via WinLab32™ software. Operating

parameters are automatically set when using PerkinElmer® Lumina™ hollow cathode lamps

Flame system (AAnalyst 800)

Gas Controls Fully computer-controlled with oxidant and fuel monitoring. Keyboard-actuated remote

ignition system with air-acetylene. Acetylene flow is automatically adjusted prior to the

oxidant change when switching to or from nitrous oxide-acetylene operation. TotalFlow™

control of the oxidant and fuel gases for constant fuel:oxidant ratio.

Safety Interlocks prevent ignition if the proper burner head, the nebulizer/end cap, or the burner drain

Functions system are not correctly installed; the liquid level in the drain vessel is incorrect; or gas pressures

are too low. Interlocks automatically shut down gases if a flame is not detected, or if any of the other

interlock functions are activated. Safe shutdown in the event of a power failure.

Burner System Premix design that can be moved automatically into the sample compartment via software control and

a motorized carriage. Alignment of the flame in the light beam is fully automatic and optimized, using

a motorized burner mount for vertical and horizontal burner adjustments. The burner is equipped with

a high-strength inert mixing chamber, angled to ensure proper drainage. Includes adjustable highprecision

nebulizer and an all-titanium, 10-cm, single-slot burner head for air-acetylene operation.

Background correction

AC Zeeman-effect background correction using a modulated 0.8 Tesla magnetic field oriented longitudinally to the

optical path. The magnet is automatically switched on during the atomization step only.

AAnalyst 800 Built-in continuum source double-beam background correction for flame operation.

Graphite furnace

Built-in computer-controlled Transversely Heated Graphite Atomizer (THGA™). The graphite tube is transversely

heated, providing a uniform temperature profile over the entire tube. An external protective gas stream around the

graphite tube prevents the entrance of outside air to maximize tube life. An internal purge gas goes through the graphite

tube to remove the volatilized matrix vapors during drying and thermal pretreatment. The two gas streams are independently

computer-controlled. Pneumatic opening and closing of the furnace for easy tube change.

AAnalyst 800 The graphite furnace can be moved automatically into the sample compartment and positioned via

software control and a motorized carriage. 

Furnace features

Program Analytical programs with up to 12 steps can be set up. Each step can be programmed with the following

Flexibility parameters:

Temperature: Ambient up to 2600 ˚C in steps of 10 ˚C

Ramp and Hold Time: 1 to 9 sec. in steps of 1 sec.

Internal Gas Flow: 0, 50, or 250 mL/min; can be switched over to another type of gas

Required Inert Gas: Argon. Inlet pressure 300 kPa (3 bar) minimum. Maximum gas consumption is

700 mL/min.

Water Coolant: A circulatory cooling system is included with the AAnalyst 800, optional for

the AAnalyst 600. When operating the AAnalyst 600 without the circulatory

cooling system, cooling water meeting the following specifications should be

used: Sediment-free drinking water; 20-40 ˚C; flow rate not less than 2 L/min;

pressure between 2.5 and 4.5 bar; pH between 6.5 and 7.5; hardness not greater

than 14˚dH or 100 ppm.

Electronics The autosampler is powered from the spectrometer and is software-controlled.

Fume extraction system

AAnalyst 600 Optional built-in device that removes all sample fumes generated during furnace drying and pyrolysis steps.

Data control system

plus data handling and storage.

Data Handling Instrument readings linear in absorbance (-0.500 A to +2.000 A), concentration or emission intensity.
