Shimadzu SPD-M10A

This used Shimadzu SPD-M10A is a photodiode array UV-Vis detector from Shimadzu's earlier generation HPLC lineup, built to provide full spectral scanning of eluting compounds during liquid chromatography analysis. It captures absorbance data across a broad wavelength range simultaneously, giving analysts spectral confirmation alongside quantitative peak data, which is useful for confirming compound identity and detecting co-elution issues during method development or routine testing. The SPD-M10A was widely used in pharmaceutical, chemical, and academic laboratories running Shimadzu HPLC systems for applications ranging from assay testing to impurity profiling. Its diode array design allows chromatographers to extract absorbance spectra at any point along a peak, supporting more confident compound identification than a single wavelength detector would allow, and it integrates readily with other Shimadzu LC modules of its era. As a pre-owned detector, this SPD-M10A has been in previous service and is offered for laboratories maintaining older Shimadzu HPLC systems or looking for a cost effective PDA detector to add spectral capability to an existing setup. It is a practical choice for labs that value proven detection technology at a reduced acquisition cost.
