Suggested Applications: food and drug safety testing, and pharmaceutical/chemical process analysis, such as cleaning validation, dissolution testing, content uniformity, surfactants and reaction monitoring.
Primary benefits: rapid results with minimal method development. HPIMS allows for analysis non-volatiles, compounds without UV chromophores, surfactants, and isomers. Unique features: can be used as a standalone analytical technique, or can be paired with HPLC or MS for two-dimensional separation. IMS separation is orthogonal to HPLC. Can be combined with MAss Spec to produce multi-dimensional data. HPIMS-MS can identify the mass of a molecule as well as provide information about its size and shape
