Two-dimensional mass spectrometry (2D MS) is a tandem mass spectrometry method that relies on manipulating ion motions to correlate precursor and fragment ion signals. 2D mass spectra are obtained by performing a Fourier transform in both the precursor ion mass-to-charge ratio (m/z) dimension and the fragment ion m/z dimension. The phase of the ion signals evolves linearly in the prec... https://www.bekindtopets.com/hot-deal-Colorado-Avalanche-Stars-Stripes-Big-Bang-Lite-Headband-flash-buy/
