ORLANDO, Fla. Competition among nano-high-performance liquid chromatographer vendors was tight at this year's Pittcon, with Waters, Dionex, Shimadzu, and Agilent, among others, claiming their technology is the best at separating proteins and peptides within complex samples.
While speed is often highlighted when presenting HPLC systems, that attribute is more relevant for small-molecule analysis than for proteomics, vendors said. For proteomics, the most important attribute of an HPLC system is its peak capacity.
