In a first part of our study we analysed urine samples (stored in liquid nitrogen) of multiple myeloma patients, treated with arsenic, in a very short time. Samples stored in such a way do not contain (almost) any trivalent arsenic methabolites. We also found out that some compounds (eg. reduced glutathion, cysteine, metallothioneine and ferritine) in blood samples can simultaneously bind arsenite and ireversibly attach to a chromatographical column.
