Hi, the peak area has no influence on the calculation of Mw when measuring with concentration detectors only (RI, UV, ELSD e.g.). When performing Viscometry & Lightscattering measurements, the peak area is needed for the calculation. As an additional…
Occasionally the tune files get corrupted and you need to go back to an old one or start again from the default atune.u file. Glad the problem is resolved!
Part 1 included many questions and some answers about the maximum abundance that should be detected at the electron multiplier. Another important consideration is how much sample should go into the column.
See Which Electron Ionization Ion Source? Part…
