TL;DR: In this paper, the origins and the fundamentals of green analytical chemistry (GAC) are discussed, and the strategies and the tools available to make sample-pretreatment and analytical methods greener.

TL;DR: In this paper, the main strategies employed in the scientific literature to reduce deleterious side-effects of extraction techniques are reviewed, and the evolution of sample-treatment procedures is focused on simultaneous improvement of the main analytical features of the method and its practical aspects.

TL;DR: In this paper, the authors focus on the possibilities offered by vibrational-spectroscopy-based techniques to make multi-component analysis of samples independently of their physical state, and discuss the main chemometric tools proposed for developing calibration models and solving problems derived from spectroscopic non-idealities (e.g., highly overlapped spectral bands or the presence of spectral nonlinearity).

TL;DR: In this article, an analytical procedure was developed for the direct determination of sugars in fruit juice samples, based on the partial least squares (PLS) treatment of first derivative near infrared (NIR) spectroscopic data obtained between 1200 and 2450 nm, using 1 mm pathlength cell and a multicomponent calibration set, including seven binary mixtures and 10 ternary mixtures of glucose, fructose and sucrose.

TL;DR: The methodology developed is proposed for direct acidity quantification and for the screening of peroxide index in edible oils, requiring less than 30 s per sample without any previous treatment.
