The development of accurate, sensitive and fast analytical methods for the determination of low levels of sulfur (S) in organic matrices is important in several applications. In this note we concentrate on the determination of S in biodiesel, but the methodology is also applicable to the determination of S (plus other elements) in other matrices such as biological materials and S-containing drugs.

In the presented work an analytical method for the quantitative determination of ethyl alcohol in body fluids with the use of the GC technique was described. A statistical evaluation of selected analytical factors of this method was presented. The described analytical method proved to be useful both in laboratory diagnosis of acute intoxication and for evidential purposes.

The ESA global astrometry space mission Gaia has been monitoring the position of a billion stars since 2014. analysis such massive dataset is challenging in terms data processing involved. In particular, blind detection and characterization single or multiple companions to (planets, brown dwarfs, stars) using requires highly efficient algorithms. this article, we present set analytical methods ...
