Horiba Scientific has patented a new technique for molecular fingerprinting. A-TEEM™ (Absorbance and Transmission Excitation Emission Matrix) simultaneously measures absorbance and fluorescence transmission. A-TEEM fingerprints molecules with high specificity and ultrahigh-sensitivity enabling researches to identify, quantify and understand dynamics of fluorescing and absorbing molecular states, and mixtures.

A-TEEM is included on Horiba’s Aqualog compact, benchtop spectrometer. Aqualog is the only instrument to simultaneously measure both absorbance spectra and fluorescence excitation–emission matrices, and these EEMs are acquired up to 100× faster than with other instruments.
