Abstract

Bright-orange floating matter (possibly algae) has been observed in the United States supply of some ampoules and in one of two 10-L primary glass storage flasks of the isotopic reference water VSMOW (Vienna Standard Mean Ocean Water). Within experimental error, ampoules with and without this orange matter are identical in stable hydrogen and oxygen isotopic composition. Thus, the North American supply of VSMOW has not been altered in isotopic abundance and remains fully functional as a primary isotopic reference material.
