Intact mass is the analysis of small molecules and proteins in their intact form prior to the digestion of fragmentation. These experiments can be performed on the Thermo QExactive ultra-high mass range (UHMR) instrument and the Thermo TSQ-Quantis triple quadrupole instrument.
Ion Mobility (IMS) is an analytical technique that separates ions in the gas phase based on their mobility in a carrier buffer. This allows a level of separation between like masses that cannot be done in the liquid state and can be done on both small and large biomolecules. These experiments can be performed on the Water Cyclic Ion Mobility instrument.
Liquid chromatography coupled with mass spectrometry (LC-MS) uses chromatographic separation of components and contaminants prior to mass analysis. This allows for sample clean-up as well as the separation of compounds of interest. These experiments can be performed on the Thermo TSQ-Quantis instrument.
Preparative LC-MS uses large-scale preparative columns to clean up synthesized compounds and collect the resulting products after chromatographic separation. This is a mass-directed system to ensure the correct final product is isolated from any side products. These experiments can be performed on the Waters Preparative LC-MS instrumentation.
