Shimadzu SPD-M20A HPLC Photodiode Array Detector (PDA)

The SPD-M20A High Performance Liquid Chromatography PDA detector provides users with the most advanced level of sensitivity and stability found in today's PDA detectors. Sharing many of the qualities of the SPD-20A/20AV UV-Vis Detectors, the SPD-M20A attains sensitivity levels approaching the most advanced UV-Vis detectors. It has a high-sensitivity mode with an 8 nm slit width. Using light-source compensation, it offers a noise level of 0.6×10-5 AU, which is comparable to that of traditional UV-VIS detectors.

Features:

Greater Baseline Stability
Supplied as standard, a temperature-controlled flow cell eliminates inconsistencies caused by changes in absorbance due to shifts in room temperature. This helps increase the baseline stability and the analysis reliability.

Superior Linearity - 2.0AU
Using newly developed signal processing technology, the stray-light correction function has been enhanced, and the linearity has been improved. This expanded linearity combines with various noise-reduction technologies to provide users with a wide dynamic range and allow for the analysis of your target compound and minor impurities in a single run.

Web Browser Control
The SPD-M20A is equipped with an Ethernet interface and Web-control functions, allowing devices to be monitored and controlled from PCs in the network. As a standalone high-sensitivity multi-wavelength detector, it can be incorporated into non-Shimadzu HPLC systems.
