Flow-Injection Preconcentration of Chloramphenicol Using Molecularly Imprinted Polymer for HPLC Determination in Environmental Samples
Figure 8
Concentration profile of 1 mL methanol sample used for elution of CAP from MIP column with flow rate 1.5 mL/min (a) and chromatogram recorded in hyphenated FIA-HPLC system using re-sampling in 775 s since starting elution from MIP column with 20 μL volume (b). In (a) preconcentrated 10 mL solution of 300 μg/L CAP. In (b) preconcentrated 10 mL solution of 30 μg/L.
