The interface allows mobile phase to contact the SPME fiber, remove the adsorbed analytes, and deliver them to the column for LC separation. It consists of a 6-port injection valve and a desorption chamber; it can be easily installed and removed.
The fiber assemblies recommended for HPLC use are crimped (rather than attached with epoxy). All have a 24-gauge needle and are suitable for autosampler-HPLC use. |
