Complete system automation can be achieved using the Model 220AS autosampler. This fully programmable, random access system provides 40 sample cups and 8 calibration/QC cups. It can also perform automatic matrix modifier additions. Sample cups can be identified in the built-in table, and method development time can be reduced substantially. 
 
Random access rotating tray accommodates 40 2ml sample vials, 8 10ml Standards vials. 
 
All positions directly accessed through 210 or 211 built-in software via RS-232 connection. Sample injection volume programmable from 1 to 50 micro-liters. 
 
Injector probe arm 7 inches long, rotates 180º for delivery to graphite tube. Two separate matrix modifier injections programmable. Extra inject and dry cycles to increase injection volumes. No external computer required for operation.
