ActiveSoil quality—Determination of total content and isotope ratio of organic carbon and nitrogen of soil and biological samples—Stable isotope ratio mass spectrometry
土壤质量 土壤与生物样品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测定 稳定同位素比值质谱法
Application Summary AI generated
This standard specifies a method for determining the total organic carbon and nitrogen content, along with their stable isotope ratios (δ13C and δ15N), in soil and biological samples using stable isotope ratio mass spectrometry. It is primarily applied in environmental monitoring, agricultural research, and ecological studies to assess soil quality, trace nutrient cycling, and identify sources of organic matter. The standard ensures accurate and comparable measurements for scientific investigations and regulatory compliance in soil and ecosystem management.
