New this year: When AIMS2100 is added-on to an existing MS or LC–MS system, it provides a simultaneous orthogonal IMS separation method for structure elucidation with MS analysis for peak identification. The AIMS2100 enables isomer determination functionality to resolve isobaric peaks, extending the analytical capabilities of established instrument suites.
Portable: 7H x 7W x 13D in.
Accessory/component: The spectrometer can be used simultaneously with any system capable of liquid sample handling
Special features: Mobility and mass data are generated on the same sample or LC peak to seamlessly
Suggested applications: Compound identification in drug discovery and development processes, reaction monitoring, content uniformity, purity checking, and cleaning verification
Primary benefits: The AIMS2100 provides a new dimension for sample analysis and offers significant performance advantages in isomer separation to otherwise mature technologies. Adds structure determination capabilities to existing separation systems.
Unique features: Separates isomers and analyzes samples without chromophores that UV detectors miss.
Manufacturer: Excellims Corporation
