Soil quality—Determination of total content and isotope ratio of organic carbon and nitrogen of soil and biological samples—Stable isotope ratio mass spectrometry


Standard in brief
Scope of Application:  
本文件描述了使用元素分析稳定同位素比值质谱联用仪(EAIRMS)测定土壤与生物样品(植物、动物、微生物)中有机碳含量与碳同位素比值、全氮含量与氮同位素比值的方法。本文件适用于土壤与生物样品中有机碳和全氮含量的测定,也适用于非标记(自然丰度)和示踪试验(f13C≤30%,f15N≤30%)的土壤与生物样品中有机碳和全氮的碳、氮同位素比值测定。本文件测定土壤与生物样品中有机碳、全氮含量和碳、氮同位素比值的定量限(以绝对碳、氮量计):碳30 μg;氮20 μg。
