Injectors and Switching Valves facilitate HPLC.

VICI Valco Instruments Co., Inc. Feb 17, 2004

Press Release Summary:

Cheminert Nanovolume HPLC Injectors and Switching Valves feature .004 in. bore that is uniform throughout flowpath, creating less than 25 nl of port-to-port volume. Individual fingertight fittings work with PEEK, fused-silica, and 1/32 in. electroformed-nickel tubing. Microelectric actuator, operating at 100 msec, determines accurate positioning without limit switches or customer adjustment. Computer control is facilitated via RS-232 or RS-485 interface.

Original Press Release:

Nanovolume Injectors and Switching Valves

Cheminert Nanovolume HPLC Injectors and Switching Valves from VICI bridge the gap between the world of microfluidics and the real world of chemical analysis, facilitating high resolution HPLC at an unprecedented small scale.

The 100Âµm (.004") bore is uniform throughout the flowpath, reducing band broadening and creating less than 25 nl of port-to-port volume. New individual fingertight fittings work with a variety of tubing, including PEEK, fused silicia (360 Âµm) and 1/32" electroformed nickel.

Our fast (100 msec) microelectric actuator determines accurate positioning without limit switches or customer adjustment. Computer control is facilitated via RS-232 or RS-485 interface.
