Impurity Analysis by High-sensitivity UV Detector

Analysis of impurities can be a challenging task especially when the main ingredient needs to be assayed at the same time, which requires a wider dynamic range and lower baseline disturbances. With an extra wide dynamic range, temperature-controlled flow cell and a stray-light correction function, both SPD-20A UV and SPD-M20A Photo Diode Array detectors offer a high level of stability, sensitivity and linearity for a confident analysis. The 100 Hz sampling of the SPD-20A/M20A ensures peak information can be captured without loss of resolution and exploits the full potential of ultra-fast LC columns.
