  1. Why not use the log index ?

  2. Dan Wispinski says:

    DHA relies on a precise retention index (RI) and a tight window to narrow the chromatographic peak’s component identification to one possibility. The DHA RI can vary slightly from column to column and the window can change with concentration.
    VUV uses a linear retention index with a much larger window (up to ±25 RI units) to obtain a library subset from which the spectral matching of the time intervals can efficiently be applied.
