FASTspectra is a proprietary technology from Bruker Anasys providing an order of magnitude increase in spectroscopy data acquisition time, resulting in high quality IR spectra in seconds. It is simply the highest performance nanoscale IR spectroscopy technique available today. It provides high quality, rich detailed spectra that directly correlates to bulk FTIR techniques providing true nanoscale FTIR

Additionally, FASTspectra laser technology extends the wavelength range of Resonance Enhanced AFM-IR to cover the 2700 to 3600cm-1 wavenumber range, setting new standards of resolution and sensitivity for nanoscale IR spectroscopy for an even wider range of applications, and still providing unrivalled correlation to FTIR spectroscopy.

FASTspectra utilizes resonance enhanced AFM-IR ability to measure on sample features of 10 nm’s as well as features with monolayer sensitivity.

IR micro spectroscopy has already demonstrated itself as a powerful tool for spatial mapping chemical content in a wide variety of applications [1-3], but has fundamental spatial resolution limits set by both the laws of optics and practical design constraints.

Atomic force microscopy (AFM) has a wide range of imaging modes but is unable to provide un-ambiguous chemical composition.

The AFM-IR technique combines the precise chemical identification of infrared spectroscopy with the nanoscale capabilities of AFM to chemically identify sample components with a chemical spatial resolution down to 10 nm with monolayer sensitivity breaking the diffraction limit by >100x.

AFM-IR absorption spectra are direct measurements of sample absorption, independent of other complex optical properties of the tip and sample. As such, AFM-IR spectra correlate very well to conventional bulk IR spectra.

Peak positions and relative intensities are highly accurate and signal to noise is extremely low, enabling detailed analysis of band shapes, subtle peak shifts, secondary structure, orientation effects and much more.

AFM-IR overcomes many of the limitations of s-SNOM based spectroscopy to provide true model free nanoscale FTIR data.

AFM-IR provides true model free nanoscale FTIR spectra and eliminates the need for modelling. AFM-IR spectra are easily exported to third party chemical libraries (e.g., Bio-RAD’s KnowItAll®) for rapid analysis and identification of unknown chemical components.
