Technical Information


The Fragment Analyzer INFINITY® Automated CE System brings parallel capillary electrophoresis with fluorescent detection to automated, high-throughput workflows. Integration of the Fragment Analyzer INFINITY into automated workflows is largely dependent on the powered sample drawer, and the ability of the sample drawer to interface with a robotic arm.

Diagram Parallel Capillary Electrophoresis Array

The Fragment Analyzer INFINITY has a single sample drawer that holds a standard 96-well plate. Samples are separated using a 96 capillary Short (33-55) or Long (55-80) capillary array. Electrodes adjacent to individual capillaries provide the appropriate voltage for electrokinetic injection of sample into the capillaries. After injection, a constant, appropriate voltage is applied to separate injected nucleic acids. At the detection window, the capillaries are arranged in parallel, passing through the optical platform.

Nucleic acid detection is accomplished with a rigorously designed optical platform comprised of an LED light source (470 nm excitation), camera lens, and CCD detector. Fluorescent light passes from the LED through the array window. The emitted fluorescence from the intercalating dye then passes through the camera lens and specific band pass filters spatially imaged onto the CCD detector. This system enables real-time detection of nucleic acid separations.

Capillary Arrays

Capillary arrays are the core of the Fragment Analyzer INFINITY affecting all aspects of electrophoresis. The array cartridges are robust, with a long lifetime, providing high quality, automated separations of nucleic acid samples. Current capillary array offerings include:

Array length is provided in centimeters with two numbers. The first number is the effective length of the capillaries - the region of the capillary that observed for separation - while the second number describes the overall length or the length of the capillary from end to end. The number of capillaries in each array directly impacts throughput, the more capillaries per array, the more samples that can be run in parallel. Array length affects both the speed of the separation and upon the separation resolution. A shorter array will provide faster electrophoresis times, while a longer array will increase separation resolution.

As a dedicated high-throughput instrument, the Fragment Analyzer INFINITY utilizes only the 96 Capillary Arrays, available in Long (55-80) and Short (33-55) lengths. Other arrays would compromise the capability of the instrument to serve as a nucleic acid analysis powerhouse.
