水、溶液、待测液中Mg Sr Ca同位素检测方案(液相色谱仪)

14083-12 ElementalScientific The prepFAST MC is a fully automated low pressure chromatography system that isolates elements ofinterest from the sample matrix and collects up to multiple discrete eluent fractions for precise isotopicanalysis. The syringe-driven system allows sample loading， multiple acid washes， column conditioning andelution cycles all at user-defined intervals (time， volume and flow rate). Figure 1. Fully-automated chromatographic separation of Sr and Ca frommatrix components that affect mass bias and contribute to isobaric， polyatomicand doubly charged interferences. In carbonate samples it is possible to alsocollect the Mg fraction during sample load and wash cycles.
