Assembling the XY Autosampler
Rack Installation
The XY autosampler is equipped to hold up to four code 21 racks (part
number for one rack G1811-04500). Place each rack into the tray so the rack
is perpendicular to the front panel of the XY autosampler. The rack code
assigned to the rack should face you. (See Chapter 5 "Parts and Supplies" for
a list of racks available for the XY autosampler.)
