Open the CIPO recordAbstract From the Canadian patent
A microchip loboratory system (10) and method provide fluidic manipulations for a variety of applications, including sample injection for microchip chemical separations. The microchip is fabricated using standard photolithographic procedures and chemical wet etching with the substrate and , cover plate joined using direct bonding. Capillary electrophoresis and electrochromatography are performed in channels (26 28, 30, 32, 34, 36, 38) , formed in the substrate. Analytes are loaded into a four-way intersection of channels by electrokinetically pumping the analyte through the intersection (40), followed by a switching of the potentials to force an analyte plug into the separation …

Why it's free to use
- Filed August 1, 1995 and granted May 8, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 1, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 1, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
