A capillary flowcell (12) includes an optical axis, the optical axis being defined by, in sequential order, (a) a first (entrance) aperture (14), (b) a first lens (26), (c) a capillary tube (16) having its long axis centered across the optical axis, and (d) a second lens (28). The first lens (26) focuses electromagnetic radiation from the entrance aperture (14), passes through the inner diameter of capillary tube (16) thus maximizing the signal generated by the analyte within the capillary tube (16). The second lens (28) focuses electromagnetic radiation which has passed through the capillary tube (16). |
