Abstract: The invention includes a high sensitivity and high throughput capillary electrophoresis multiwavelength florescence detection system. The fluorescent detection system is configured to illuminate a relatively large volume of a single capillary or a plurality of capillaries, with a pixelated detection system capable of imaging an area of each capillary that differentiates the capillary walls, the space between the capillaries, and the internal liquid volume within the capillary. Only the desired pixels or image area are used for processing and generating an output signal.

Abstract: A multi-wavelength detector for a multiplex capillary electrophoresis system comprising a linear filter placed in between the capillary detection windows and a 2-dimensional detector. The linear filter is oriented such that the change in wavelength of the filter is in the direction of flow of the fluid within the capillary detection windows. And a method for time shift correction and to merge all peaks into a single overlapped peak.

Abstract: The present invention provides a simple method to correct cross-talk, after the data have been generated. Adjacent signals are simply subtracted from the original observed signal with a repeating process. The data processing is stopped when a predefined condition is met. By this technique, cross-talk can be reduced from >5% to less than 0.1%. And as an additional advantage, this method provides a way to correct the cross-talk without the need to know which peaks are caused by the adjacent capillary signal.

Abstract: The invention is a high-throughput multi-capillary system utilizing a 2-dimensional mask onto which the detection windows of the capillaries are lined up in alternating columns and rows. The image of the capillaries is projected onto a 2-dimensional detection system, such as a charge-coupled-detector (CCD) array. Each row and column of the capillary detection windows is imaged in a separate area of the CCD array, which results in reduced cross-talk between capillaries.

Abstract: Using multiple dichroics mirrors to split and redirect different wavelength regions of light in a multi-wavelength fluorescence detection system.

Abstract: The invention includes a method of sample profiling for identification. The method includes the steps of performing less than four nucleotide-specific chemical cleavage reactions to obtain nucleotide sequence fragments, performing size separation on the fragments, detecting the fragments' separation, generating a profile based on the detection, and comparing the profile to a data base to identify the sample.

Abstract: A multiplexed, absorbance-based microfabricated chip electrophoresis system, microfabricated chip, and method of use are included for the detection and identification of protein species. The microfabricated chip electrophoresis system capable of analyzing multiple samples simultaneously. The system uses a microfabricated chip having a sample chamber for first dimension separation of a sample, a first planar array of channels for second dimension separation of the sample approximately perpendicular the sample chamber, and a barrier separating the sample chamber from the first planar array of channels during the first dimension separation. In use, the sample is placed into a sample chamber, a barrier is established around the sample chamber, the sample is isoelectric focused within the sample chamber, the barrier is then removed, and the sample separated in the first array of channels by molecular weight.

Abstract: A system for the rapid detection of microbial contamination in a fluid sample such as water, involving the use of a filter material having a surface adapted to receive the sample in order to retain substantially all microbes from the sample on the filter surface under conditions that minimize the potential for contamination from sources other than the sample itself, and in a manner that permits the filter surface to be incubated in order to grow viable microbes contained thereon, in combination with a growth medium and an analytic instrument to permit analysis of the filter surface, within a predetermined incubation period, in order to determine whether the growth onset of viable microbes that may be present on the surface has begun.
