The AAnalyst 200 offers a no-compromise approach to atomic absorption - from sample introduction to results. Confusing keyboards and small screens have been replaced with a large, full-color, easy-to-use touchscreen, meaning virtually no training is required. This AAS has a lamp slot. The plug-and-play modular design ensures easy maintenance and enables quick replacement of components for rapid service, saving time and getting the device back into service immediately. The AAnalyst 200 changes the way instruments are used and maintained, while maintaining the high performance PerkinElmer expects. The system integrates innovations normally only offered in expensive research equipment. True dual beam Echelle optics combined with the power of a solid state detector delivers performance levels not typical of flame AA. Fully automated gas controls and integrated safety checks result in the safest flame AA system available today. Taxes and data system. User Interface: Complete control of the AAnalyst™ 200 via an innovative touchscreen interface. Flexible software for lamp setting, flame control, parameter setting and sample analysis. The tools menu provides access to recommended conditions, sample information, method storage and retrieval, data transfer, and service diagnostic screens. Display: Full-color 10.4-inch LCD touchscreen. VGA resolution (640 x 480 pixels). Coated for maximum durability and lifespan. Data processing: Analyzes can be set up on the parameter page. Users can select up to eight calibration standards or one repeat standard and have a choice of seven different calibration algorithms. The integration times can be selected by the operator from 0.1 to 60 seconds. Printing options include method, replicates and calibration curve. Signal measurement modes include time-averaged integration, manual continuous graphs, and peak height measurement. An optional footswitch to trigger a measurement is also available. Sample Analysis: The Sample Analysis page is used for manual or automated analysis. All results are displayed on the screen. Separate buttons for blanks, standards and samples make analysis easier. Sample ID and dilution factor are available on this page as entered in the tool/sample information menu. The calibration curve can be displayed and printed with correlation coefficient, slope and intercept. Tips can be viewed and printed using the MHS-15 accessory. Accessories: Automated analyzes can be performed using a PerkinElmer® Autosampler and the Sample Information Tool. The MHS-15 can be used for the determination of hydride-forming elements and mercury. Hardware. System: True double beam Echelle optical system. Front surface reflective optics with protective coating. Deuterium background corrector and built-in EDL power supply are available on some models. Optical system: Echelle monochromator. Focal length: 300mm Grid: 36 x 185 mm area, 79 lines/mm, blaze angle 76°. Fused quartz prism: 95 x 40 mm, 60°. Wavelength range: 189-900 nm. Spectral bandwidth: 0.15 nm at 200 nm. Reciprocal linear dispersion: 2.4 nm/mm. The photometer optics are covered to protect against dust and corrosive fumes. For maximum protection, the optical system can be purged with an inert gas. Detector: High performance segmented solid state detector. Light sources: Hollow cathode lamps (HCLs) and electrodeless discharge lamps (EDLs). EDLs offer significantly higher luminous efficacy and longer lifespan compared to conventional HCLs. Lamp elements, recommended operating currents and gap selection are automatically detected and adjusted when PerkinElmer Lumina™ AA lamps are used. Lamp alignment is fully automatic in models with a four-lamp turret. Electronics. Processor: Internal 300 MHz GX1 with 64 MB DRAM and 128 MB flash program memory on a PC104 interface style board. Includes real time clock. Graphics: 32-bit controller on PC104 board. Ports: RS232C, 9-pin, parallel printer and 10BaseT Ethernet on some models. E-Box: All electronics are contained in a single, user-replaceable module. The operator can simply pull the module out of the front of the device and replace it with a new one. Equipment operators can quickly and easily replace most parts without requiring maintenance. Labprocure is responsible for this equipment.
