can anyone tell me how to increase injection volume on an agilent 1100 series autosampler. its max is 100uL.

i have a 400uL loop. is this what i need? if so where to put it?

if you could tell me where to find the info that will work too.

thanks

Check out this appnote for details on how to extend your injection capacity up to 1800 uL:

"Large-volume injections of 1800 μL were made possible by installing the 900-μL injection upgrade kit (Agilent p/n G1363A) that includes a 900-μL analytical head, 900-μL stainless steel loop extension (Agilent p/n G1313-87303), 900-μL needle (Agilent p/n G1313-87202), and 1,400-μL extended
seat loop (Agilent p/n G13G13-87308) installed between the seat capillary fitting and injection port 5 of the analytical head."
