目的富含有机质的生物样品,灰化是必要的,沿用法在灰化时,发生氟(F)的损失和污染,因为来自固定剂的 F 问题较多。因此,将低温等离子体灰化法试验应用于前处理,用 F 电极法与 GC 测定低温灰化后的血清及血浆中的氟,一面比较两者,一面研究与用分析精密度及无灰化直接 F 电极法 Purpose A biological sample rich in organic matter, ashing, is necessary. In use, ashing occurs, fluorine (F) losses and contamination occur because of F problems from fixatives. Therefore, the low temperature plasma ashing test is applied to the pretreatment, the F electrode method and the GC are used to measure the low-temperature ashed serum and plasma fluorine, while comparing the two with the analysis precision and without ashing Direct F electrode method
