Optimization of the Agilent 1260 Infinity Binary LC

How to Configure the Optimum Delay Volume

Extra-Column Volume

Extra- column volume is a source of peak dispersion that will reduce the 
resolution of the separation and so should be minimized. Smaller diameter 
columns require proportionally smaller extra- column volumes to keep peak 
dispersion at a minimum. 

In a liquid chromatograph the extra- column volume will depend on the 
connection tubing between the autosampler, column, and detector; and on 
the volume of the flow cell in the detector. The extra- column volume is 
minimized with the Agilent 1260 Infinity Binary LC due to the 
narrow- bore (0.12 mm i.d.) tubing, the low- volume heat exchangers in the 
column compartment and the Max- Light cartridge cell in the detector.
