Typical methods for the analysis of mixture components include multiple linear regression,
partial linear squares, and artificial neural network. However, these methods need large …

We demonstrate the possibility of inspection of chemical mixtures by terahertz (THz)
spectroscopic imaging using known spectral data of the pure chemical components. This …

Preservatives are universally used in synergistic combination to enhance antimicrobial
effect. Identify compositions and quantify components of preservatives are crucial steps in …

Terahertz spectroscopic images of paraffin-embedded cancer tissues have been measured
by a terahertz time domain spectrometer. For the systematic identification of cancer tumors …

Terahertz spectroscopy has been widely used for investigating the fingerprint spectrum of
different substances. For cancerous tissues, the greatest difficulty is the absorption peaks of …

A rapid technique is necessary to detect the natural gas which is a more and more
significant fuel resource in modern industry. Terahertz (THz) technique was employed in this …

In the field of anti-illicit drug applications, many suspicious mixture samples might consist of
various drug components—for example, a mixture of methamphetamine, heroin, and …

An approach for automatic identification of terahertz (THz) spectra of biomolecules is
proposed based on principal component analysis (PCA) and fuzzy pattern recognition in this …

Chemometrics was applied to qualitative and quantitative analyses of terahertz spectra
obtained in transmission mode. A series of mixtures of three pure analytes, namely, citric …

We achieved high identification accuracy of reagents hidden by thick shielding materials, by
combining injection-seeded terahertz (THz) wave parametric generator measurements and …
