Shimadzu SPD-M20A Prominence Photo Diode Array Detector

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.


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.

The GenTech Difference

Why Buy New When You Don't Have To? Our refurbished Shimadzu HPLC Systems have been expertly restored to meet OEM standards. GenTech is a full service reseller, our knowledgeable engineers perform installations, repairs, training and method development. The inventory in our 60,000 sq. foot facility is constantly changing with new shipments coming in daily. GenTech customers receive lifetime phone support for all instruments they purchase.

How we refurbish used analytical instruments

Every refurbished instrument we sell under goes a complete inspection of all electronics and performance review. The instruments undergo in-depth preventative maintenance procedures that include extensive cleaning, detector maintenance, line and pump flushing. Routine maintenance is also addressed and filters, liners, tubing, etc. are all replaced as needed. Our chemist perform full calibration and data verification. Once used Shimadzu HPLC Systems are returned to like-new condition and will run your samples for 30-80% off retail.

This refurbished Shimadzu SPD-M20A Prominence Photo Diode Array Detector is calibrated to meet OEM standards. Our expert service engineers and chemists can install and custom configure the system to be compliant with the Methods you plan to run.
