Up to date, most studies are focused on sample pretreatment methods for GC/IRMS analysis, isotope fractionation mechanics in physical-chemical processes and biodegradation. CSIA has been successfully used in environmental pollution assessment.

• 目前的研究,主要集中在GC IRMS样品前处理技术、物理化学过程所导致的同位素分馏、不同有机化合物在生物降解过程中的同位素分馏过程诸方面,并初步应用于一些受污染环境的评价中。
