For a high level of automation and easy-to-use software —at a mid-range price— the PC-controlled true double beam 240 AA system combines rugged and reliable hardware with acclaimed Windows-based worksheet software. Use multi-tasking capabilities to start a new analysis while simultaneously preparing a report on past results. The 240 AA comes standard with the world’s leading flame atomization system, the Mark 7 flame atomization system. The Mark 7 spray chamber is simple to use with twist and lock assembly and made from plastic components for durability.
Features:
- Designed for dusty, corrosive environments—completely sealed optics with quartz overcoated mirrors; optional air purge continually cleans the inside of the instrument to exclude corrosive vapors.
- Fast response background correction—the high intensity deuterium background corrector has a fast 2-ms response time ensuring accurate correction of transient background signals.
- Easy lamp maintenance—the lamp is immediately accessible for easy adjustment or replacement without needing to remove the instrument covers.
- Automation to fit the need and budget—Automatic wavelength and slit selection, four fixed-lamp positions for quick, reliable lamp changes, and a next lamp warm-up feature that saves analysis time.
- Expandable—analyze mercury and hydrides at trace ppb levels using the continuous flow vapor generation accessory (VGA 77). Add the ETC 60 for unattended, flameless atomization of hydride elements.
- Upgradable—The 240 AA can be easily upgraded at any time.
- Reduces ownership costs—Rapid troubleshooting and fault diagnosis keep your lab up and running faster. The Telediagnostics option connects to a worldwide network of on-line support personnel.
In Feb 2012, Agilent rationalized the AA product from 25 models with over 400 possible configurations to 14 models which included the most popular configurations including as standard; auto lamp selection, double beam for all flame instruments, and GTA camera on all GFAA models.
The spectrometer provides:
- The light source
- Control of the sample and reference light beams
- Atomizer/burner and adjustment
- Control of the combustible gas mixtures and uptake rates of the analyte solution
- Overall process management of the instrument functions
