Description

Hg in a solution of 0.5 M HCI+0.05% (m/v) K2Cr2O7

This certificate is valid until 6/2014; this validity may be extended as further evidence of stability becomes available. The material can be regarded as a homogenous solution.

Package
The samples are supplied in flame-sealed glass ampoules and contain about 0.2 µmol of mercury in 5 ml of a hydrochloric acid solution. The matrix is 0.5 M sub-boiling distilled hydrochloric acid +0.05% (m/v) potassium dichromate.
