Coulochem detector for microdialysis

[Dr V.A. Russel, Chemiese Patalogie]

I need advice on the purchase of a detector for catecholamines in 
microdialysis perfusates i.e. fg/20ul sensitivity. I have an existing BAS 
200 HPLC with built-in amperometric detector. I need to know whether there 
will be any advantage in purchasing a coulochem detector to use in place of 
the amperometric detector. Will I get 10x - 100x improved sensitivity?

Your help will be greatly appreciated
Sincerely
Vivienne Russell
