This column mounting bracket is designed to be used with LaChromElite L-2200 autosamplers and Chromaster manual injector holders.
In the LaChromElite systems without column oven the only possibility to mount columns at the L-2200 autosampler is by using this special column mounting bracket. Just mount it to the base of the L-2200 with the two special nuts using a 7 mm wrench. The two additional holes will support the standard column holder from LiChroGraph series.
For Chromaster systems you can combine the column mounting bracket with the manual injector holder (903-0508) with two additional distance bolts.
