electrophoresis and HPLC techniques to co nventional ICPMS or High Resolution ICPMS Using as little as 5 gL of solution we can conveniently speciate a number of metals for their inorgan ic or organic metal species This allows determination of a number of metal species sequentially Actlabs can consult on the best ways to preserv e samples for speciation analysis Note Minimum of 10 samples Pore W

preservation of water for analysis is 02 2 mLL of concentrated ultra pure nitric acid This may be inadequate in alkaline environments The acid should be added only after the sample has been collected and not as precharged acid in bottles which may leach metals from the bottle When filling the bottle it should be rinsed with the sample water twice before retaining the sample It should then be acidified A test of pH using pH paper will indicate if the pH after acidification is adequate pH 2 Depending on the sample composition preservation with nitric may invalidate Ag As Br and I analyses W e require 30 mL of water for analysis Samples for Hg should be preserved with 05 BrCl as the GSC study indicates the conventional preservation method of K 2 Cr 2 O 7 in 01 HNO 3 may be inadequate to keep Hg in solution W e require 30 mL of water for Hg in a glass bottle Do not freeze water as it will cause precipitation of some elements Samples should be shipped to the lab as soon as possible for analysis Gold unfortunately is not stable and will be adsorbed onto the sides of the bottle within a short period of time hours Samples for ion chromatography should not be preserved at all Code 6 HRICPMS method removes these metals fr om the plastic bottle and puts it back into solution for analysis directly by HRICPMS Please inquire for a list of preservation and bottle types for the di f
