Requirements for screening and confirmatory methods for the detection and quantification of marine biotoxins in end-product and official control ArchiMer
Hess, Philipp.
An overview is given of the biological origin of phycotoxins, as well as their chemical characteristics. Major poisoning types are described and examples of poisoning events are given to illustrate the importance of the phenomenon to both shellfish consumers and the shellfish producing industry. The characteristics of phycotoxins as natural products, the lack of predictability of their occurrence, economic drivers and the freshness of shellfish consumed in many countries result in a number of requirements for methods to be used in the efficient detection of these compounds. Subsequently, the performance of mouse bioassays and mass spectrometry as detection tools are compared for examples from Irish and French monitoring programmes to assess the usefulness...

Quantitative analysis of phenobarbital in biological fluids: Analyte enrichment by an electrically-assisted microextraction technique BJPS
Yaripour,Saeid; Ebrahimi,Shahriar; Mohammadi,Ali.
An electrically-assisted microextraction method called electromembrane extraction, followed by a simple high performance liquid chromatography and ultraviolet detection was developed and validated for determining phenobarbital in biological samples. The major parameters influencing the electromembrane extraction procedure including solvent composition, voltage, pH of acceptor and donor solutions, salt effect, and time of extraction were evaluated and optimized. The drug was extracted from the donor aqueous sample solution (pH 9) to the acceptor aqueous solution (pH 13). The donor and acceptor phases were separated by a hollow fiber dipped in 1-octanol as a supported liquid membrane. A voltage of 40 V during 20 minutes was applied as the driving force. The...
