Nexera HPLC/UHPLC Photodiode Array Detector - SPD-M40

SPD-M40 Photodiode Array Detectors for UHPLC and UHPLC

Boost your high sensitivity measurements over a wide wavelength range. The SPD-M40 has great accuracy in identification of compounds from absorbance spectra and performs an impurity check on all peaks. The industry leading i-PDeA deconvolution algorithm spectrally resolves coeluting peaks. The newly designed optical system guarantees both a wide linearity range and a superb signal-to-noise ratio performance at the same time. It has improved stability in analysis through flow cell/polychromator/lamp compartment temperature control. Each SPD-M40 is equipped with a UV cutoff filter, which allows even less variation and more robust analysis by minimizing sample decomposition.
