Liquid injection by the PAL is characterized by a combination of precision, reproducibility and flexibility.
The syringe is additionally capable of aspiring and injecting air cushions, solvents or internal standards. The liquid injection in HPLC devices is performed by UHPLC control valves and sample loops for all CHRONECT Symbiosis systems. The injection into the LC injection port is realized by the Constant Force Technology. Here, the injection head moves into the injection port until a defined counter-pressure is reached. Combining this technique with a specifically developed needle sealing a potential dead volume during injection is prevented.
