High-Performance UVC LEDs Driving Spectroscopy Innovations
new breed of spectroscopy devices that are smaller, less costly and more energy-efficient, while still delivering precise, real-time measurements. With efficiency and performance levels that rival traditional lamp-based systems, UVC LEDs are an integral component in new instruments for a range of applications, including high-performance liquid chromatography (HPLC), water-quality monitoring and process monitoring in the food and beverage industry. Granted, LEDs are an established technology, offering a small footprint, ease of alignment and enhanced end-user productivity. But adoption of earlier sapphire substrate UVC LEDs in the 250- to 280-nm range was relatively limited due to performance and reliability issues.
