An Improved Urea Adduction Method for Analyzing Carbon Isotope of ppm-level n-alkanes in Soil and Plant Samples
Both the urea adduction method and 5Å molecular sieves are used to separate straight chains from branched/cyclic hydrocarbons, however, the recovery of the low concentration of n-alkanes are generally low due to the complex process. Through optimizing experimental conditions of urea adduction method...
