1,2-linked hexose disaccharide standard for MSMS analysis

[Paul.McJarrow at NZDRI.ORG.NZ]

Hi,
    Possibly just having a mental blockage on this one. I am
looking for a source of a 1,2 linked disaccharide (hexoses in
pyranosyl form) to act as a standard for our MSMS analysis of
oligosaccharides. Any help much appreciated.
