To all:

            For research requirements, we have changed the mobile phase of HPLC System #7 from .005M H2SO4 to 5% Acetonitrile in .005M H2SO4. This means that if you are now using System # 7, you can try the new mobile phase to analyze your sample or if you want to use the original mobile phase, you can move to Systems #1 or #4.

            Please follow the new HPLC system setup (see below):
