A recent publication in a biotech journal acknowledges a Top 10 pharmaceutical company has utilized Digilab's sample preparation and fractionation technologies to expose standard and novel diabetes substrates in a Fourier Transform Mass Spectroscopy experimental paradigm (Yates, et al. To remove this long-range variation, the as-acquired data are processed using a band-pass Fast Fourier Transform filter. Each Fourier transform F(Q) equals the volume integral [8] of the respective [rho](r)exp(-iQ * r), Q denoting the wave vector transfer. |
