Patent ID: 8778155

Claim:
A cartridge for bio-separation, comprising: a body, defining an opening as a detection window for receiving external detection optics; at least one capillary column supported in the body, having a first end extending beyond a first end of the body, wherein the detection window exposes a section along the capillary column, to which the external optics are aligned through the detection window; and a reservoir attached to a second end of the body in fluid flow communication with a second end of the capillary column, wherein the reservoir comprises a nipple having a through-hole supporting the second end of the capillary column, wherein the nipple is threaded to a base of the reservoir, wherein the capillary column is supported coaxially by two ferrules that are supported in the body, wherein each of the ferrules is cantilevered by the body and having an end extending into the detection window, and wherein a detection zone along the capillary column is exposed between the extended ends of the ferrules.
