Pesticides are vital to the success of crop production. Regulatory agencies have set maximum residue levels (MRLs) for hundreds of pesticides and their metabolites in foods. Most MRLs are set at low ppb levels, posing significant challenges to screen and quantify hundreds of analytes in complex food matrices simultaneously.
In this presentation, we demonstrate the screening and quantitation for 246 pesticides and metabolites using Ultivo Triple Quad LC/MS.
Ultivo is designed to address many challenges faced by routine production labs , especially in the environmental and food safety arenas. Innovative technologies within Ultivo allowed us to reduce its overall footprint, while conversing the comparable performance level of much larger MS systems.
Innovations, such as VacShield, Cyclone Ion Guide, Vortex Collision Cell and the Hyperbolic Quads, not only maximize quantitative performance in a small package, but also enhance instrument reliability and robustness, which promote greater uptime.
Moreover, Ultivo reduces the need for user intervention for system maintenance, making the system operation and maintenance manageable for non-expert MS users. MassHunter Software simplifies data acquisition, method set up, data analysis and reporting, which results in the fastest possible acquisition-to-reporting time, increasing lab productivity.
The Use of Pyrolysis/GCMS and Newly Developed Libraries to assist in Characterizing Complex Polymeric SamplesPoster
Pyrolysis-GC/MS is an effective tool in introducing and analyzing polymers. But since the polymer must be broken down to volatile segments in order to be sent to the GC, identification by the Mass Spec does not look at the original polymer, but only the fragments. This poster will look at a unique library designed to work with the existing NIST library, however contains averaged spectra of pyrolyzed polymers so it can be used to directly identify the original polymer sample.READ MORE
Application of Solid Phase Micro Extraction (SPME) and On‐Fiber Derivatization to Detect Precursors of Biomolecules in the study of Proto‐metabolismPoster
In the studies of origins of life, plausible synthetic reaction pathways to form biological relevant molecules, or building blocks of proto‐bilayer lipids, protein, RNA, and DNA in the primitive environment have been investigated intensively.READ MORE
A New Tool for the Automated Sample Preparation of Whole Blood Samples by LC-MS using a Commercial AutosamplerPoster
Automated sample preparation reduces the costs per sample and minimizes sample handling errors. Usually expensive and highly specialized pipetting robots are used. However, most of these systems are not designed with a direct interface for LC-MS applications. In addition common pipetting systems are not optimized for smaller scale sample series. Here we present a new tool for liquid handling of whole blood samples and direct sample injection.READ MORE
