Additional information from the Spectroscopy (other) section of the Pittcon Review article.

Manufacturer: Excellims Corporation

Product name: AIMS2100 ESI-HPIMS

Ion mobility spectrometer

For: Lab and process analysis

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

Product name: GA2100 high-performance ion mobility spectrometer (HPIMS)

Ion mobility spectrometer

For: Lab and process analysis

New this year: A Directspray electrospray ionization (ESI) source enables users to analyze samples directly from standard syringes.


Portable: 18.5H x 15W x 18.4D in.

Accessory/component: ESI ionization source that can be directly interfaced to an autosampler for batch sample processing

Description: Interfaces typical autosampler systems with the ESI source combine electrospray with IMS.

Special features: A common analysis can be completed in seconds with only a few microliters of sample

Suggested applications: At-line or on-line process analysis; compound identification, reaction monitoring, content uniformity, purity checking, on site environmental monitoring, on site food safety inspection, and cleaning verification

Primary benefits: Separates compounds by size and structural shape

Unique features: User-interchangeable sample introduction and ionization methods tailored to their application.

Manufacturer: Horiba Scientific

Product name: Microvolume Accessory

Accessory for all HORIBA fluorescence spectrofluorometers

For: Lab analysis

New this year: The Microvolume Accessory allows any HORIBA spectrofluorometer to perform measurements on as little as 1 μL of sample.

Accessory/component: Cuvette adapter

Measurement mode: Steady-state and lifetime fluorescence (90°)

Description: This drop-in accessory fits into the cuvette holder of any HORIBA fluorometer and allows ultralow-volume measurements.

Special features: Optimized optics allow highest efficiency of signal collection. A removable sample chamber.

Suggested applications: synthesized/purified molecule analysis; bodily fluids analysis; immunoassay development; protein synthesis process control; nanomaterial characterization

Primary benefits: The Microvolume Accessory gives the user the advantages of both a low-cost microvolume add-on to their existing fluorometer and the sensitivity of a full-size-cuvette instrument.

Unique features: Easy to clean, resistant to carryover.

Manufacturer: Horiba Scientific

Product name: Fluorolog EXTREME AND Fluorcube EXTREME

Supercontinuum laser-powered spectrofluorometers

For: Lab analysis

New this year: first integration of a supercontinuum white-light laser into a commercial spectrofluorometer. Fully integrated optically and software-wise
