Abstract: The present invention is thus directed to an automated system and method of varying the optical path length in a sample that a light from a spectrophotometer must travel through. Such arrangements allow a user to easily vary the optical path length while also providing the user with an easy way to clean and prepare a transmission cell for optical interrogation. Such path length control can be automatically controlled by a programmable control system to quickly collect and stores data from different path lengths as needed for different spectrographic analysis. Such a methodology and system, as presented herein, is able to return best-match spectra with far fewer computational steps and greater speed than if all possible combinations of reference spectra are considered.

Abstract: An image analysis system includes a video camera that collects YUV color images of a liquid sample disposed between a capital and a pedestal, the color images being collected while a light source shines light through an optical beam path between the capital and the pedestal, and a processor adapted to i) obtain from the YUV color images a grayscale component image and a light scatter component image, and ii) obtain at least one binary image of the grayscale component image and at least one binary image of the light scatter component image.

Abstract: An apparatus includes a first pedestal surface coupled to i) a swing arm and to ii) a light source. The apparatus further includes a magnet, a base plate, a mechanical stop coupled to the base plate, and a second pedestal surface mechanically coupled to said base plate and configured to receive a liquid sample, said second pedestal surface being coupled to a spectrometer. The apparatus further includes a magnetic flux sensor located between north and south magnetic flux fields of the magnet such that the magnetic flux reaching the sensor while the mechanical stop is in physical contact with the swing arm provides a linear range of output of the magnetic flux sensor, and a processor adapted to calibrate the point for minimum optical path length using a threshold magnetic flux field emitted from the magnet and detected by the magnetic flux sensor.
