] One of the challenges of proteomics is sample size. ] Researchers need to fractionate complex protein mixtures ] into their component parts for subsequent analysis, but ] the miniscule quantities and volumes involved preclude ] standard large-scale chromatography. Three years ago ] Agilent Technologies, headquartered in Palo Alto, Calif., ] introduced its 1100 series capillary LC system, featuring ] tiny tubes that could pump nanoliter volumes through ] columns with high accuracy. Now the company is following ] that up with a microfraction collection system for single ] or multidimensional separation of protein and peptide ] mixtures.
