Sample Preparation Ezine


Fish antibiotics probed Fish antibiotics probed 
Veterinary antibiotics have been released from fish and mussels by enzymes with the aid of an ultrasonic probe, which reduces the extraction time from several hours to just a few minutes, say Spanish researchers. [August 23, 2010]


Solvent-enhanced headspace sorptive extraction in the analysis of the volatile fraction of matrices of vegetable origin Solvent-enhanced headspace sorptive extraction in the analysis of the volatile fraction of matrices of vegetable origin  [registered users only]
Solvent-enhanced headspace sorptive extraction, which aims to modify PDMS polarity using a solvent to increase its concentration capability, was applied to sample the volatile fractions of sage, thyme and roasted coffee. [August 16, 2010]


Eggy SPE Eggy SPE 
Eggshell membranes are more effective adsorbents than octyl- or octadecyl silica particles for solid-phase extraction, say Chinese researchers, who used them to extract linear alkylbenzenesulphonates from river and tap water. [August 9, 2010]
