The role of compound-specific isotope analysis (CSIA) in environmental research has been proven over the last few decades. Despite advances analytical methods and instrumentation, applying CSIA to low-concentration contaminants, especially at field scale, remains limited. In this perspective paper, we argue that limitation stems from underdeveloped sample preparation techniques, particularly lack required selectivity. Drawing an extensive review nearly 600 studies on (i) analyze methodologies' distribution dedication studies, discussing their connection with maturity suitable techniques. Additionally, (ii) examine general trends sorbent phase technologies, assessing adequacy meet CSIA's targeted nature applicability micropollutants. advocating for a paradigm shift, (iii) emphasize need adapt future development strategies light past current innovations.
