Emilie NEMS-FTIR Spectrometer
The EMILIE is a nanoelectromechanical system-based Fourier-transform infrared spectroscopy (NEMS-FTIR) analyser for bulk chemical analysis of nanoparticles and thin films. It combines the large spectral range of the INVENIO FTIR spectrometer with picogram sensitivity of the nanoelectromechanical system (NEMS).
Product Overview
EMILIE: NEMS-FTIR Analyser
The Bruker EMILIE™ is a pioneering nanoelectromechanical system (NEMS) accessory designed to expand the capabilities of Bruker VERTEX and INVENIO research-grade spectrometers. By utilizing a silicon nitride nanomechanical resonator as the sensing element, it shifts infrared detection from traditional semiconductor physics to mechanical motion. This transition allows the system to achieve picogram-level sensitivity, making it a unique solution for the bulk chemical characterization of nanomaterials that were previously too small or too dilute for standard FT-IR analysis.
A significant breakthrough of the EMILIE system is its ability to analyze aerosols and nanoparticles in the sub-micrometer range. Traditionally, bulk FT-IR analysis of small particles was hindered by the diffraction limit and insufficient sample mass to generate a measurable signal. The EMILIE overcomes these barriers, allowing researchers to capture and analyze aerosols (down to 10 nm) and ultrafine powders directly on the sensing chip. This opens new frontiers in the study of nanoplastics, biopharmaceuticals, and environmental pollutants where sample quantities are extremely limited.
Engineered for high-end research environments, the EMILIE operates entirely at room temperature, eliminating the operational costs and complexity associated with liquid nitrogen cooling. It is equipped with a wedged diamond window, ensuring a wavelength-independent photothermal detection principle that provides gapless access across the Near-IR, Mid-IR, and Far-IR/THz regions. This combination of extreme sensitivity and broad spectral range makes the EMILIE an indispensable tool for characterizing the molecular fingerprints of the smallest matter.
