Determination of benzene in different food matrices by distillation and isotope dilution HS-GC/MS

headspace GC / MS. Based on the results of the DOE, a versatile method for the extraction of benzene from all kind of food commodities was developed. The method which consisted of distillation and isotope ...

Determination of benzene in different food matrixes by distillation and isotope dilution HS-GC/MS

Publication Type: Scientific poster, presentation or proceeding Authors: R. Medeiros Vinci; Michael Canfyn; De Schaetzen,T.; Ilse Van Overmeire; De Meulenaer,B.; Joris Van Loco Source: 4th international Symposium in Recent Advances in Food Analysis (RAFA) ...

Accuracy and reproducibility of automated estradiol-17beta and progesterone assays using native serum samples: results obtained in the Belgian external assessment scheme.

frequently used in Belgium for estradiol-17beta (E(2)) and progesterone. Results obtained were compared with values determined by reference method, isotope dilution-gas chromatograph/mass spectrometry (ID- GC ...

A downscaled multi-residue strategy for detection of anabolic steroids in bovine urine using gas chromatography tandem mass spectrometry (GC-MS3).

applied analysis method resulted in a procedure for which high performance liquid chromatographic (HPLC) fractionation prior to GC- MS (n) analysis was no longer required. Analytical results could be ...

Prime-boost strategies combining DNA and inactivated vaccines confer high immunity and protection in cattle against bovine herpesvirus-1.

cellular arms of the immune response primed with Bovine herpesvirus-1 (BoHV-1) DNA vaccines encoding glycoprotein D (gD) or gC+gD. Calves vaccinated according to the DNA prime-inactivated boost also showed ...

Inhibition of bovine sperm-zona binding by bovine herpesvirus-1.

was treated with monoclonal antibodies against the viral glycoproteins gB, gC, gD and gH prior to insemination. Anti-gC completely prevented the inhibitory effect of BoHV-1 on sperm-zona binding, while ...

Arcobacter cibarius sp. nov., isolated from broiler carcasses.

hybridization with reference strains of the current four Arcobacter species revealed binding levels below 47 %. The G+C contents ranged between 26.8 and 27.3 mol%. Pairwise comparison of 16S rRNA gene sequences ...

Acinetobacter diversity in environmental samples assessed by 16S rRNA gene PCR-DGGE fingerprinting.

species. PCR using the Acinetobacter primer pair allowed detection of Acinetobacter in soil with a detection limit of 10(4) cells g(-1) soil, but attachment of the GC-clamp to the forward primer resulted in ...

TEQ-value determinations of animal feed; emphasis on the CALUX bioassay validation

July 2002. The results evidence good agreement between TEQ-values obtained by either CALUX or GC- HRMS. The method is now routinely in use for a feed screening programme designed by the Federal Agency ...
