VICI”s Cheminert Nanovolume HPLC injectors and switching valves bridgethe gap between the world of microfluidics and the real world ofchemical analysis, facilitating high-resolution HPLC at anunprecedented small scale. The 100µm (.004″) bore is uniform throughout the flowpath, reducingband broadening and creating less than 25 nl of port-to-portvolume. New individual fingertight fittings work with a varietyof tubing, including PEEK, fused silica (360 µm), and 1/32″electroformed nickel. The company”s fast (100 msec) microelectric actuator determines accuratepositioning without limit switches or customer adjustment. Computer control is facilitated via RS-232 or RS-485 interface.
