Nano injector
Easy realization of nanoliter sample injection.
This micro-injector features new innovations in the rotor section, allowing for the precise injection of extremely small samples of approximately 20 nL. This enables direct sample injection even with columns of 0.1 mm inner diameter, without the need for concentration columns or valves. Since the column can be directly connected, the dead volume is extremely small, minimizing sample diffusion. It has excellent features such as the ability to accurately introduce known quantities of samples into the system and its usefulness in flow injection analysis. By combining it with our electric field-filled capillary columns (ChemcoPak-e series columns: Patent No. 322401), a high-performance capillary liquid chromatography system can be constructed.
