Traditional nanospray mass spectrometry has proven its 
potential as a cost-effective, sensitive and reproducible 
technique for the identification of peptides at femtomol to 
atomol levels. However, connecting nano capillaries, columns 
and valves frequently is a tedious procedure and requires user 
skills and routine. When handled incorrectly, nano flow 
connections are prone to leakage which are difficult to detect 
and result in poor system performance and extended downtime 
of the complete system. Quartz nanospray needles are prone to 
blockages and require frequent replacement.
With the invention of HPLC-Chip technology, Agilent is 
significantly reducing the need for user interaction and making 
nanospray a rugged state-of-the-art technology. See the 
documentation for the HPLC-Chip for more information.
