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.
Intelligent Peak Deconvolution Analysis (i-PDeA) is a data analysis technique that extracts a single peak from co-eluted peaks and quantitates it by exploiting the differences in spectra between each compound. i-PDeA II enables users to visualize and detect a minor single impurity even when the impurity is co-eluted with an analyte. It also facilitates the separation of hard-to-separate peaks on the column through computer processing and deconvolution of the spectrum information, which reduces the effort required to investigate separation parameters.
When you apply i-PDeA, you can selectively visualize only the components you want to view, even peaks that are not separated!
Even though the difference in absorption wavelength between 1,2-dimethoxybenzene (274.2 nm wavelength) and 1,3-dimethoxybenzene (273.6 nm) is only 0.6 nm, the individual chromatograms can be obtained!
