“…With the discovery of chemically reduced P-species in samples from environmental water sources, a new method has been reported for phosphate, phosphite and hypophosphite, which have now become the focus of environmental P-speciation studies. The use of a conventional IC system with a conductivity detector coupled to SF-ICP-MS in medium resolution mode has been developed, 113 utilising a small clean-up column included as part of a 2 valve injection system. Commonly, IC has been used for quantifying the concentration of different species of the same element such as nitrate and nitrite, bromide and bromate, chloride and perchlorate in natural and experimental solutions.…”
