In recent data, we encountered a problem with peptides, that are so stable they do not undergo exchange in both states. For our own use, we call them "płaszczaki". The issue is that the maximal exchange control is very similar to the minimal exchange control, and when calculating the fractional deuterium uptake, the uncertainty is very high and it influences the houde confidence limit very much.
