The invention provides methods and systems for ruggedizing a nucleic acid analyzing apparatus. The ruggedized apparatus can be used reliably and effectively in uncontrolled environments, such as, for example at a crime scene to collect and analyze forensic data, as well as in semi-controlled environments, such as, for example at a point of care location. 1. A system for finding the position of separation channels in an electrophoresis system comprising an electrophoresis chip and an instrument capable of separating and detecting of DNA fragments labeled with at least one fluorescent dye comprising:(a) a removable electrophoresis chip comprising:a substrate having top and bottom surfaces, further comprising an anode portion, a cathode portion, and a separation channel between the anode and cathode portions, andhaving top and bottom surfaces such that the top surface of said substrate layer is bonded with the bottom surface of said cover layer to form at least one microfluidic channel,a first via located at said anode and in fluidic communication with at least one of the microfluidic channels,a second via located at said cathode and in fluidic communication with at least one of the microfluidic channels,a detection zone located in the separation channel; and(b) an electrophoresis instrument capable of receiving said chip, comprising,(i) a processor,(ii) an optical system, said optical system comprising said fluorescence excitation energy beam, and at least one photodiode, positioned on a first side of said chip when said chip is inserted into said instrument, and at least one light detector, and,(iii) an electrical system for delivering said beam to said detection zone, and having an anode and a cathode, said anode in contact with said anode portion of said substrate, and said cathode in contact with said cathode portion of said substrate, andwhereby the processor directs the beam to pass through the detection zone, and the scattered light from the separation channel ...
