A precise, robust and rugged RP HPLC method for simultaneous analysis of CF, BA, PP, BP, BHA and BHT was developed to investigate 41 marketed dairy products within a shortest possible time.
Chemometric tools equipped with a Plackett Burman (P B) design, a central composite design (CCD) and a desirability profile were employed to optimise the QuEChERS (quick, easy, cheap, effective, rugged and safe) method for the quantification of thiacloprid, spirotetramat and spirotetramat's four metabolites in pepper.
The goal of this work is to develop and validate a simple, sensitive, rapid, rugged, and reproducible assay method for the quantitative determination of SF from rat plasma samples.
However, the RP method was found to be more precise, more accurate, and, more importantly, more rugged than the HILIC method for maintaining the analytes' peak shape symmetry in high-throughput operation.
The main goal of the present study is to develop and validate the novel simple, higher sensitive, selective, rapid, rugged, and reproducible bioanalytical method for quantitative determination of SF in rat plasma by LC-MS/MS with a small amount of sample volume.
Response surface methodology was employed to optimize a quick, easy, cheap, effective, rugged, and safe (QuEChERS) sample preparation method for the determination of 42 different analytes in dairy products for the first time.
The strong correlation between aboveground vegetation properties and SOC suggests that measurement of vegetation properties by remote sensing could represent a feasible and rapid method for estimating SOC distribution in a rugged terrain.
The aim was to design a method for surface temperature normalisation of forest stands in rugged relief.

Homogenized food samples were extracted using a modified QuEChERS (quick, easy, cheap, effective, rugged, and safe) method (Schenck et al. 2009) originally developed for rapid multiresidue determination of OP insecticides in fresh fruits and vegetables at the 1-ng/g level (Anastassiades et al. 2003; Podhorniak et al. 2001; Wong et al. 2007).
