Preservation of physical parameters and major ions in waters / by V. Cheam, A.S.Y. Chau, K.K. Kwan.: En13-5/85-112E-PDF
"The centralization of the Water Quality Branch (WQB) laboratories involves longer time periods between sample collection and sample analysis. It was therefore essential that the sample preservation techniques currently in use be thoroughly evaluated and modified where required, if the data generated by the consolidated laboratory are to be reliable. This report describes the results of the first phase of the preservation studies. It deals with a total of 16 physical and inorganic parameters, Sixteen regional, spiked and synthetic waterswere investigated over a four-month period. It was found that most parameters investigated are stable when stored in plastic containers in the dark at 4°C."--Abstract.
