Description
Rheodyne, Valco, Beckman Coulter, Altex and SSI Injection Valve Microliter Syringes For Volatile Organic Samples
HPLC syringes are especially designed for manual or automatic injection within high pressure ports. The needle is blunt and electro-polished to slide smoothly into the injection port reducing the wear on critical seals. The selection of the appropriate syringe for HPLC applications takes the following three aspects into account: the type of injection valve, the sample properties and the injection volume. The volume of the syringe should be adjusted to the volume of the injection. In partial loop filling, the injection volume should not be greater than half of the loop capacity. In complete loop filling, where the loop size sets the injection volume, the syringe capacity should be greater than twice the loop volume.
