Monitoring Bromethalin Poisoning in Wildlife: Analysis of Adipose Tissue using EMR-Lipid Sorbent

Presenter:  Mike Filigenzi (California Animal Health and Food Safety Laboratory, University of California, Davis, USA)
Sponsor:  Agilent Technologies

Bromethalin is a potent neurotoxic rodenticide. Recent restrictions on the use of second generation anticoagulant rodenticides are likely to result in increased use of bromethalin with subsequent increases of poisonings in non-target species. Post mortem diagnosis of bromethalin poisoning can be accomplished via analysis for desmethylbromethalin, the active metabolite of bromethalin. Results of such testing in our laboratory indicate that adipose tissue is the preferred sample type for this analysis. Separation of desmethylbromethalin from fat is challenging; it is a fairly hydrophobic compound as indicated by its reverse-phase HPLC behaviour.

The aliquots are divided between LC- MS/MS and GC-MS/MS and analyzed for the total of ~500 residues. The webinar will highlight the versatility, time and cost effectiveness of using the EMR kit versus other sample preparation techniques for botanical matrixes.

Improved LC-MS/MS Pesticide Multiresidue Analysis using Triggered MRM and On-Line Dilution 

Presenter:  Dr Katerina Mastovska (Covance Laboratories, Greenfield, Indiana, USA) 
Sponsor:  Agilent Technologies  

This webinar will discuss development, optimization and performance of a large LC-MS/MS pesticide multiresidue method for separation of about 450 analytes within 10 minutes. The method uses so called Triggered MRM function, which enables acquisition of additional MS/MS transitions for increased confidence in analyte identification. Acetonitrile extracts (prepared using a QuEChERS-based extraction) are injected directly without a need for a dilution with an aqueous buffer/solution prior to the injection because the LC system employs on-line dilution ensuring excellent peak shape of early eluting (more polar) analytes. The method was validated for routine use in multiple food matrices.

Advanced HPLC Method Development Using Quality by Design

What does it cover?

The central tenant of Quality by Design (ICH Q8) is that quality cannot be tested into a product – instead it must be designed into the product. When the product is an HPLC method, QbD strategies can guide the development process to result in a standardized method development prcedure, more easily validated methods, and methods that are easier to use and adjust in routine applications.
 “Advanced HPLC Method Development Using Quality by Design” is an intensive online class that teaches you strategy and technique to develop high-quality HPLC and UHPLC methods quickly and with confidence. You will learn a time-proven technique that walks you through the method development process a step at a time using sound chromatographic principles to help make the process more efficient. The techniques can be used as a stand-alone strategy or added to existing development procedures to help streamline the process. Because the same principles apply to HPLC and UHPLC, you can apply the same information for the development of UHPLC methods.

LC-MS/MS for Chromatographers

What does it cover?

With the introduction of the mass spectrometer (MS) as a practical detector for a high-performance liquid chromatograph (LC or HPLC) in the early 1990s, LC-MS began to be used for routine applications. One form of LC-MS uses a tandem MS (LC-MS/MS), that has become the go-to instrument for quantitative analysis of drugs in biological matrices in the pharmaceutical laboratory. As they have become more widely used and understood, LC-MS and LC-MS/MS have found their way into environmental applications, synthetic chemistry, protein analysis, and many other areas. LC-MS/MS has moved from a technique available only to skilled experts in both HPLC and MS to a routine tool usable much as any other HPLC detector. You will find that this introductory course in LC-MS/MS will give you a good foundation of understanding the technique and how to use it in your daily work. We start out with an overview of different MS techniques, and focus in the majority of the course on the quadrupole mass spectrometer. You will learn how MS works, how ions are produced and fragmented. Sections focus on qualitative, as well as quantitative analysis. Each part of the process, calibration, tuning, sample preparation, HPLC method development, and MS method development are covered. Many tricks and techniques of practical use are presented.

What will I get from this course? 

You will learn how a mass spectrometer works, the advantages (and limitations) of adding mass spectrometric detection to your liquid chromatographic analyses, and how to use MS to approach separation and detection problems intractable by other methods. By understanding the central roles of the LC-MS interface and the sample ion, you will have a solid grounding on which to further build your LC-MS expertise. You will receive a printed copy of the approximately 515 slides included in this course to supplement your note-taking as you view the class.
