Adding the Dilutor to a PAL extends its sample prep capabilities. It can be used to dispense liquid prior sample injection and combines the “add liquid” and “inject” steps without user intervention or syringe change. Typical applications are dilutions, derivatisations, sample spiking or standard additions. Dilutor syringes up to 10ml ensure large dilution ratios. Another important Dilutor application concerns the injection valve and syringe wash procedure in LC-MS high throughput systems. Replacing the standard Fast Wash Station, the Dilutor can be used to clean the injection syringe as well as the injection valve at the same time. This results in shorter cycles times, which are the key factor in today’s screening labs. The PAL Dilutor can be controlled by the Cycle Composer software.
