“…The technique uses supercritical fluids that have similar densities to liquids, but lower viscosities and higher diffusion coefficients. This combination of properties results in a fluid that is more penetrative has a higher solvating power and extracts solutes faster than liquids 69 . Using automation, SFE reduces labor and laboratory space.…”

“…Kaihara et al (2000Kaihara et al ( , 2002 have developed the SFE method that combined with the purification on PSA and florisil columns may be used for determination of 27 pesticides in cucumber, potato, radish, apple, banana and rice samples. Norman & Panton (2001) have developed the SFE method for determination of OPPs in wheat and maize using GCB (graphitized carbon black), and Quan et al (2004) found out that SFE of ginseng followed by purification on C18, gave satisfactory results in determining OCPs. The same sorbent was shown to be the best choice for determination of 32 pesticides in soil using SFE sample preparation (Rissato et al, 2005b).…”
