The spectral analysis is achieved using vector analysis algorithms (Gorenstein, et al., LC-GC 12, no.10, 1994, pp.768-772).

WebTraditional Peak Purity algorithms, based on cosine vector comparison of spectra at select points across the peak, are one way to assess potential coelution. This approach can confirm the presence of a coeluting peak but is unable to assist with characterizing or quantifying such a peak. WebPDA has other advantages in that the spectral profile may assist in determining an unknown peak in the chromatograms. For full confirmation, analyses should be performed by mass spectrometry. In the pharmaceutical industry the PDA is often used to determine peak purity of the target compound.
