On-line SPE
On-line SPE columns for coupling with LC analysis
SPE technique can be coupled on-line to HPLC for a high sensitivity or for limited amount of sample.
ON-LINE SPE PROCEDURE STEPS
An on-line SPE column containing the SPE sorbents is coupled within the injection loop of a six-port rotary valve. The on-line SPE column is reusable.
1- Sample injection: The valve is configured with the injector directly in contact with the on-line SPE column. The sample is injected and goes through the on-line SPE column where the analytes remain.
3- Analysis: The valve is switched. The analytes are eluted out of the sorbent by the LC mobile phase and transfered into the analytical column for their analyses.
