NEW GENERATION OF DEEP-UV LEDS INCORPORATED IN PORTABLE ROBUST LOW COST DETECTORS FOR MICROFLUIDIC AND MINIATURISED ANALYSIS
Original language description
An effective use of optical detection, especially in microfluidics, aimed at portable, robust and relatively inexpensive platforms requiring inexpensive, commercially available, miniaturized, robust and analytically well performing light sources. The advantages of simplicity, low cost and efficiency is represented by detection systems using light emitting diodes (LEDs) as light source with a special attention to recently developed new generation of deep-UV LEDs (below 300 nm). Previous generations of deep-UV LEDs had significant drawbacks such as low optical power (in the range of μW), strong parasitic emission in the visible spectrum, short lifetime and excessive heat generation .The new generation of deep-UV LEDs has significantly improved these characteristics. In this work we investigated optical performance of new generation of deep-UV LEDs with emission maxima at 255 and 280 nm. The optical power and emission spectra were tested. These LEDs were used in in-house photometric detector for use in a portable capillary FIA and LC system based on a microfluidic platform. The application of this detector was demonstrated for isocratic LC separation of parabens.
