Abstract: The present disclosure relates, in some embodiments, to a system for measuring capillary electrophoresis current. The system includes a plurality of capillaries (206), where each capillary has a cathode end and an anode end. The system further includes a plurality of cathode buffers (202). Each of the cathode buffers is configured to be electrically isolated from the other cathode buffers. Further, each cathode buffer (202) is associated with one capillary (206) of the plurality of capillaries. The cathode end of each capillary (206) is immersed in its associated cathode buffer (202). The system includes a plurality of current sensors (204), each current sensor associated with one capillary of the plurality of capillaries for measuring current. In some embodiments, the plurality of capillaries is four capillaries.

Abstract: A biological analysis system is provided. The system comprises an interchangeable assembly configured to accommodate any one of a plurality of sample holders, each respective sample holder configured to receive a plurality of samples. The system also includes a control system configured to cycle the plurality of samples through a series of temperatures. The system further includes an optical system configured to detect fluorescent signals emitted from the plurality of samples. The optical system, in particular, can comprise a single field lens, an excitation source, an optical sensor, and a plurality of filter components. The excitation source can be one or more light emitting diodes. The field lends can be a bi-convex lens.
