Ultra-Fast and High-Sensitivity Analysis of Artificial Colorings Using the SPD-M30A Photodiode Array Detector

The newly-designed capillary SR-Cell (Sensitivity and Resolution Cell) has been adopted for the SPD-M30A high-sensitivity photodiode array detector in the Nexera SR Ultra High Performance Liquid Chromatograph. By optimizing the cell's optical path length and diameter, both low noise levels and high sensitivity have been achieved. This article introduces the high-speed, high-sensitivity simultaneous analysis of artificial colorings using the Nexera SR UHPLC and a high-sensitivity cell (option).
