عضو 		Basic Model Overview

211 Atomic Absorption Spectrophotometer
• Unique non-flame ignitor provides the safest instrument start-up
• Simple 3 button operation for fully automatic gas controls, ignition and gas switchover (Air to Nitrous Oxide)
• Automatic optimization of analytical parameters when method files are loaded from the 211's built-in Methods Library
• Fully integrated safety interlocks for gas pressure sensors, burner head type, UV flame sensor, drain line trap and ignitor continuity insure safe operation of the 211 AAS
• Upgradable to the model 220GF back-mounted graphite furnace for ppb/ ppt trace level analyses
• Available autosampler, hydride generator and cold vapor attachments
• Internal microprocessor and software can identify samples, perform statistical analysis and graphically display calibration curves and transient peaks (Hydride generation & Graphite furnace)


210VGP Atomic Absorption Spectrophotometer
• High energy optical system for superior sensitivity
and detection levels
• Dual background correction system (D2 & VGP) for difficult sample matrices
• Comprehensive microprocessing for methods storage and data manipulation
• Three lamp turret for multi-element analysis
• Small footprint for mobile applications


210VGP/220 Stabilized Temperature Graphite Furnace AA
