Alzaga et al. extracted Pirimicarb (a pesticide present in sediments of rivers) using supercritical CO2 modified with triethylamine and compared the results to those obtained with the conventional Soxhlet method (Alzaga et al., 1995). The supercritical fluid method offered increased precision, shorter analysis time, and a 10-fold reduction in solvent usage. [Pg.244]

Many analytes that are not amenable to GC (e.g., thermolabile compounds) can be separated by SFC. Separations via SFC are often more efficient and faster than traditional LC analyses. Wider coverage of supercritical fluid methods can be found in the literature on SFC. " This technique has also been employed for the determination of carbamate pesticides in environmental samples (see Table 24.5). ... [Pg.920]
