if the fiber is desorbed in a solvent different than mobile phase ,switch the valve to the LOAD position ,fill the valve desorption chamber with the solvent, and allow the fiber to soak in the solvent (statc mode)for a minimum of 15 minutes .the background can be checked by switching the valve to the INJECT mode and monitoring baseline throughout the run cycle .the fiber may need addition conditioning if the background is not sufficiently clean .minimal cleaning is usually required ,but cleaning time often depends on the type of detection and sensitivity
