MSPD as sample preparation method for determination of selected pesticide residues in apples [PDF]
Acta Chimica Slovaca, 2017 Abstract A method for extraction and fast gas chromatographic (GC) determination of twenty pesticide residues of different volatility and polarity at ultratrace concentration level in apples is presented. Apples as representatives of non-fatty food were chosen as a matrix; they are also a common raw material for baby food production ...

The crystal structure of dypingite: understanding the long-range disorder. [PDF]
J Appl CrystallogrAfter 55 years, the average crystal structure of dypingite is finally revealed. Our research shows that ambient humidity controls long‐range disorder within this mineral and unlocks its potential as a tunable, non‐toxic material for developing next‐generation functional materials.Dypingite, a hydrated magnesium carbonate hydroxide mineral [Mg5(CO3)4(OH)

Analysis of pesticide residues in rice using matrix solid-phase dispersion (MSPD) [PDF]
Journal of the Brazilian Chemical Society, 2004 This work reports a multi-residue extraction method based on matrix solid-phase dispersion (MSPD) and capillary gas chromatography - electron capture detection for quantification of two widely used organophosphorus insecticides (malathion and parathion-methyl) and an organochlorine pesticide (b-endosulfan) in rice.
