  To Denis Rinkacs re S-35:

  Any chance that you are seeing interference from C-14, which has
  a similar energy?  Is the investigator generating sulphur dioxide or
  hydrogen sulphide?  My Amersham wall chart also warns that radiolysis
  of S-35 amino acids during storage and use may lead to the release of
  S-35 labelled volatile impurities.  Although impurities may be a small
  percentage, contamination of internal surfaces of storage and reaction
  vessels may occur.  They also recommend that vials be opened and used
  in ventilated enclosures.

  Hope this helps.
