Validation of the measurement of Aluminium in food by ICP-OES after acid digestion
ICP- OES was performed, during which the precision, trueness and quantification limits (LOQ) of the measurement were determined. An expanded measurement uncertainty could be calculated. Keywords: ...
A simple multi-residue method for the determination of pesticides in fruits and vegetables using a methanolic extraction and ultra-high-performance liquid chromatography-tandem mass spectrometry: optimization and extension of scope.
performance of the method including limits of quantification (LOQ s), linearity, matrix effect, precision was evaluated during validation in accordance with the European Union SANCO /1257½013 regulatory ...
Fast and discriminative CoSYPS detection system of viable Salmonella spp. and Listeria spp. in carcass swab samples.
spp. The results showed that the relative level of detection and the limit of detection of the complete workflow and ISO reference methods are in a range from 2 to 16 CFU /swab for both bacteria. The ...
Parasite distribution and associated immune response during the acute phase of Toxoplasma gondii infection in sheep.
the detection limit three weeks after infection. This coincides with an increase in parastic-specific serum IgG1 and IgG2 and a decrease of the antigen-specific IFN-gamma response in PP, PBMC and ...
Validation of a sensitive DNA walking strategy to characterise unauthorised GMOs using model food matrices mimicking common rice products
on model food matrices mimicking common rice products, have allowed to determine the limit of detection as well as the potential effects of food mixture and processing. This detection system allows the ...
Evaluation of viability-qPCR detection system on viable and dead Salmonella serovar Enteritidis.
monoazide (PMA) coupled with PCR (viability PCR) is used in foodborne pathogen detection in order to detect only viable bacteria. Originally presented to fully remove the signal of dead bacteria, the limits ...
Proteomic detection as an alternative for the quantification of Staphylococcus aureus enterotoxins
existence of the toxins in foods and immunoassays are not specific enough, not suitable for quantification and more importantly limited in the range of toxins they can identify. The proteomic approach method ...
A two-step lyssavirus real-time polymerase chain reaction using degenerate primers with superior sensitivity to the fluorescent antigen test.
