Detection of Morphine and Morphine-Glucuronide in Saliva or Urine with a Rapid and Simple Method Without Derivatization on the Varian 500-MS

Jason S. Wood, Ph.D. Varian, Inc. Introduction Testing for drugs of abuse (DoA) is becoming more prevalent in various environments, including forensics and social justice environments as well as in sporting events. Non-heroin opiates such as morphine, oxycodone, and...

Quantitation of Acrylamide in Food Samples on the Finnigan TSQ Quantum Discovery by LC/APCI-MS/MS

...for the analysis of acrylamide, this method requires extensive sample cleanup and chemical derivatization.6 The advantage of LC/MS/MS is that chemical derivatization is not necessary prior to acrylamide analysis. To date, most LC/MS/MS methods for the assay of acrylamide have utilized an electrospray ioni...

Analysis of ()-11-Nor-9-Carboxy-Delta-9-THC in Urine by Negative Ion Electrospray LC/MS/MS

...metabolite testing, requires time consuming sample derivatization prior to analysis. LC/MS provides the same specificity and sensitivity without the need for a derivatization process. A simple, high throughput LC/MS...he method eliminates the need for a time-consuming derivatization step which can take an hour or more. The Varian 12...

High sensitivity quantitation of metabolites of nitrofuran antibiotics in animal tissue using LC/MS/MS

...les were prepared by homogenization, organic solvent washes, hydrolysis and derivatization followed by liquid-liquid (L-L) extraction before analysis. The limits of d...itrofuran antibiotics in chicken tissue via their metabolites. The one step derivatization improves non-specific fragmentation and poor MS detection sensitivity of th...

Determination of the Chloramphenicol residues in milk and milk products using LC/MS/MS

..., before the samples can be analyzed. LC/MS, on the other hand, requires no derivatization and can be directly analyzed, minimizing possible derivatization problems, saving time, and preventing compound losses. This paper...
