Groton Biosystems is dedicated to capillary electrophoresis and understands the modern laboratory's need to utilize an array of in-line detector technologies in its day-to-day routines and methods development work. In an effort to facilitate optimum capillary electrophoresis in your laboratory, Groton Biosystems offers a variety of easily integrated solutions to optimize detection at the capillary scale.

The VUV-14 Absorbance Detector is a fixed wavelength light absorbance monitor designed to be used with ultra-low volume sampling cells under flowing solvent conditions (i.e. Chromatography). The VUV series of detectors has a high-resolution analog output with a sensitivity range from 4.0 AU/V to 0.0005AU/V and features a state-of-the-art noise level of less than +/- 0.00001 AU.

The VUV-14D can work at any wavelength in the range from 190 to 1000 nm provided the appropriate interference filter is installed in the instrument for the desired wavelength. It is composed of a high reliability lamp, an interference filter, true double beam sample/reference light paths, a low RI high sensitivity HPLC flow cell (standard) and a robust universal power supply. The resultant design is a rugged, low maintenance source for obtaining reliable results in a variety of applications.

All of our detectors are modular and are compatible with CE, HPLC and FIA applications. These detectors can easily be mounted externally to Groton Biosystems HPCE units or any other supplier's systems that are compatible with external detection systems. It is possible with our detectors to develop multiple, serial detection strategies for those difficult samples or to optimize information content of those trace quantity samples that every lab encounters from time to time. Groton Biosystems HPCE instruments can even be easily interfaced to your Mass Spectrometer providing the ultimate in HPCE detection.
