Does the observation of noncovalent complexes between biomolecules by electrospray ionisation mass spectrometry necessarily reflect specific solution interactions?

Electrospray ionisation mass spectrometry is used to observe complexes formed between porcine pancreatic elastase (PPE) and its peptidic substrates and products; analogous complexes are observed between PPE and the enantiomers of the substrates and products.
