A Fibre-loop Ring-down Spectroscopy Detector for HPLC
> Printer friendly version
Description:
Researchers at Queen’s University have developed a rugged and inexpensive absorption detector based on a patented fibre-loop ring-down spectroscopy (FLRDS) technology. The ring-down of a pulse of light (from near infrared to UV) in a loop made of fiber-optic waveguide is correlated to changes of analyte concentrations in a sample stream. Coupling with various separation instrumentation (e.g. capillary electrophoresis, micro-HPLC, or microfluidic devices), this detector allows for a fast and sensitive detection of a broad range of organic species, proteins/peptides, and suspended particles in a few nano-litre of sample streams.
Benefits:
Applications:
This detector can be used essentially wherever a UV detector applies such as in pharmaceutical industry to:
Potentially, it may also be used for online process or quality monitoring where chemical or physical changes are involved.
Status of Commercialization:
PARTEQ Innovations, the technology transfer arm of Queen’s University, has sought patent protections worldwide, and is currently seeking industrial partners willing to collaboratively develop or license the technology.
