high throughput quantitation of seven Sulfonamide residues in dairy milk using laser diode thermal desorption negative mode atmospheric pressure chemical ionization tandem mass spectrometry
Journal of Agricultural and Food Chemistry, 2010Co-Authors: Pedro A. Segura, Patrice Tremblay, Christian Gagnon, Pierre Picard, Sébastien SauvéAbstract:Sulfonamides are antibiotic compounds widely used in the dairy industry. Their presence in diary milk poses a risk to public health and may also contribute to the spread of antibiotic resistance in bacteria. Sulfonamide residues in dairy milk were quantified by tandem mass spectrometry (MS/MS) using a novel ionization source based on laser diode thermal desorption-negative mode atmospheric pressure chemical ionization (LDTD-APCI(−)). Seven Sulfonamides spiked in milk were extracted with acetonitrile, which yielded high recoveries (77.5−101.5%). Calibration curves in the matrix showed good linearity (0.9977 ≥ R2 ≥ 0.9658) over the dynamic range (1.6−500 μg L−1), and limits of quantitation were between 2 and 14 μg L−1, lower than or of the same magnitude as maximum residue criteria set by several regulatory agencies (10−100 ng L−1). In addition, the run time using the LDTD-MS/MS system was 30 s per sample, as compared to actual methods running from 7 to 84 min for the same Sulfonamide residue compounds, whi...

High-throughput quantitation of seven Sulfonamide residues in dairy milk using laser diode thermal desorption-negative mode atmospheric pressure chemical ionization tandem mass spectrometry
Journal of Agricultural and Food Chemistry, 2010Co-Authors: Pedro A. Segura, Patrice Tremblay, Christian Gagnon, Pierre Picard, Sébastien SauvéAbstract:Sulfonamides are antibiotic compounds widely used in the dairy industry. Their presence in diary milk poses a risk to public health and may also contribute to the spread of antibiotic resistance in bacteria. Sulfonamide residues in dairy milk were quantified by tandem mass spectrometry (MS/MS) using a novel ionization source based on laser diode thermal desorption-negative mode atmospheric pressure chemical ionization (LDTD-APCI(-)). Seven Sulfonamides spiked in milk were extracted with acetonitrile, which yielded high recoveries (77.5-101.5%). Calibration curves in the matrix showed good linearity (0.9977 >or= R(2) >or= 0.9658) over the dynamic range (1.6-500 microg L(-1)), and limits of quantitation were between 2 and 14 microg L(-1), lower than or of the same magnitude as maximum residue criteria set by several regulatory agencies (10-100 ng L(-1)). In addition, the run time using the LDTD-MS/MS system was 30 s per sample, as compared to actual methods running from 7 to 84 min for the same Sulfonamide residue compounds, which gave the method the high screening throughput capacity necessary for monitoring milk production.
