SPD-M40 Diode Array Detector - Good Condition 2022

Shimadzu SPD-M40: high-performance diode array detector

The Shimadzu SPD-M40 is a diode array detector designed to meet the demands of the most accurate chromatographic analyses . It combines a wide spectral range from 190 to 800 nm with remarkable sensitivity, enabling reliable identification of a wide range of compounds. Thanks to its i-PDeA II deconvolution algorithm, it is possible to spectrally separate co-eluting peaks, providing better resolution and clearer interpretation of results. This device is particularly suitable for laboratories looking for a reliable solution for multi-wavelength detection and analysis.

Performance and accuracy for compound identification

The SPD-M40 excels in the accuracy of compound identification thanks to the quality of its absorbance spectra and its meticulous control of optical parameters. The optical system has been completely redesigned to combine an extended linearity range with an exceptional signal-to-noise ratio, resulting in more reliable measurements even at low concentrations. Control of the temperature of the optical bench, flow cell and lamp compartment ensures optimum stability during analysis, reducing variations and ensuring increased reproducibility of results.

Ease of use and application flexibility

The SPD-M40's ergonomic design and versatility make it easy to integrate into a variety of analytical environments. It can be monitored and controlled directly via a standard web browser, without the need for complex software. An integrated UV cut-off filter reduces light below 240 nm, minimising sample decomposition and improving the robustness of the analysis. In addition, the flow cells are user-interchangeable, offering several configurations to suit your needs: UHPLC, semi-micro, inert, preparative or high pressure. The Cell ID function automatically records information about the cell used in the analysis data, facilitating tracking and traceability. With its multiple features, this detector is a reliable and accurate tool for chromatographic analyses requiring sensitivity, stability and flexibility.
