we bought a nanospray setup for the LCQ from PROTANA (Odense, Denmark).
We are also using their capillaries, which cost $2 a piece. I am very
satisfied with the setup. If you want more information you can visit their
website (http://www.protana.com). I am sure you can assemble your own
nanospray setup and you will probably get several responses about doing
just that. The advantage of the PROTANA system is that you can buy
everything you need in one package.
Let me know if you need further info.
