A method and apparatus for illuminating a subject with deep UV light and detecting 2-dimensional image information, e.g., a transmission image, fluorescence image, reflected light image, etc. The subject may be illuminated with a light pulse having a duration of 2 seconds or less and one or more components with a wavelength of between about 150 nm to about 300 nm. The light pulse may be arranged so as to minimize or eliminate any detrimental effect on the functioning of the subject, e.g., on a living cell. A concentration, mass, quantum yield, absorbance or other characteristics of one or more compounds in the subject may be determined based on one or more 2-dimensional images obtained of the subject. An illumination beam having left and right circularly polarized components may be generated, e.g., for circular dichroism analysis of a subject.

A technique processes a sample of biomolecular analyte. The technique uses an apparatus having a support assembly that receives and supports a test module, a load assembly that loads the sample of biomolecular analyte onto the test module, an electrophoresis assembly that applies a current to the test module such that components within the sample separate by electrophoresis, and a controller that controls operations of the load assembly and the electrophoresis assembly. The load assembly and the electrophoresis assembly are coupled to the support assembly. The controller controls the operation of the load assembly in an automated manner. Preferably, the test module includes a dielectric plate member having an upper planar surface and a lower planar surface that is spaced apart from and coplanar with the upper planar surface. The dielectric plate member has at least one set of channels that includes an injection channel and a separation channel. The injection channel extends from the upper planar surface to the lower planar surface. The separation channel extends within the dielectric plate member in a plane parallel with the upper and lower planar surfaces and intersects the injection channel.

An electroelutor provides electroelution and concentration of small amounts of proteins from sample gels. The electroelutor elutes desired molecules from gels in a sample holder directly onto a membrane of a centrifuge concentrator or a sequencing membrane. After electroelution, the eluted molecules can be concentrated or processed in a sequencing device with minimized sample handling and minimized disturbance abou
