There are numerous sources of chemical reference materials
on the market. However, many of these do not accurately
disclose the level of purity of the compound, the
means by which purity was assessed, or utilize accurate
means for assessing purity.
A number of investigatons by AHP-collaborating laboratories have revealed numerous significant inaccuracies in the declaration of the purity of commercial refereence materials. AHP-Verified™ Chemical
Reference Standards have been independently verified
as to their identity and level of purity. Each standard
is accompanied by a full documentation package with
the level of purity and the method for determining
purity clearly indicated.
