Field Asymmetric Ion Mobility (FAIMS) - Mass Spectrometry
Field Asymmetric Ion Mobility Spectrometer (FAIMS) is a high speed, gas phase ion separation technique. When interfaced to a Mass Spectrometer, the FAIMS chip provides an additional separation stage, making it suitable for a applications ranging from drug development to proteomics.
The FAIMS ion filter is orthogonal to both LC and MS, so has the potential to separate analytes that are difficult to distinguish using only LC-MS. In some cases, the FAIMS stage can replace the LC and associated sample preparation steps.
