Abstract:
An optical emission spectrometer system includes a light source and a dichroic beam combiner. The light source emits first light in a first direction and second light in a second direction different from the first direction. The dichroic beam combiner receives the first light via a first light path and the second light via a second light path, reflects a portion the first light into an entrance aperture of a light detection and measurement apparatus, and transmits a portion of the second light into the entrance aperture, enabling analysis and measurement of both first and second light characteristics simultaneously. The portion of the first light reflected into the entrance aperture predominately has wavelengths in a first range of wavelengths and the portion of the second light transmitted into the entrance aperture predominately has wavelengths in a second range of wavelengths, different from the first range of wavelengths.

Abstract:
A method and apparatus for the archival storage of tissue sections which have been cut from a sample block by a microtome blade includes a tape bearing serially-spaced areas of adhesive material, generally the same size as the surface of the tissue sample block. The tape may be delivered from a feed reel by a feed roller mechanism. Between each cut, the tape is advanced to align the adhesive area on the tape with the tissue sample. An application roller presses the adhesive against the sample, the section is cut, and a takeup roller lifts the tape and section away from the blade. The tape may then be wound onto a takeup reel for archival storage. The entire process may be automated, including the operation of a transport mechanism to move the apparatus away from the tissue sample during microscopic imaging.
