This afternoon session will be presided over by Rick King of PharmaCadence Analytical Services and will be held from 2:30–4:30 p.m. in Ballroom 220/221.
The first presentation in the session will be given by Leanne Grafmuller of Pfizer and is titled “The Evaluation and Development of Automated Workflows in Blood, Plasma and Urine Using Volumetric Absorptive Microsampling (VAMS).” Grafmuller will discuss the aims of her group’s work to devise an automated sample preparation and extraction protocol using Mitra and direct-inject analysis of sample extracts using HILIC chromatography to streamline bioanalytical workflows.
The next talk, to be delivered by Brian Rappold of Essential Testing, is titled “Calibration Curve Sensitivity: The Role of Internal Standard on Slope and Precision of Clinical LC-MS/MS Assays.” This work will address the effect of internal standard concentration and response on the sensitivity of endogenous and exogenous assay calibration.
The third talk will be given by Kasie Fang of GlaxoSmithKline and is titled “LC-MS/MS and LC-HRMS Approaches to Support Toxicity Studies of a Glycolipid Vaccine Adjuvant.” Kang will discuss a sensitive and robust LC–MS-MS method that was developed to provide bioanalytical support for toxicity studies with varied species and matrices.
Tom Van De Goor of Agilent Technologies will give the next talk titled “Improving Quantitative Analysis through Reduction of Matrix Suppression Effects by coupling Multi-Dimensional Chromatography to ESI-MS.” Van De Goor’s talk will focus on the benefits for accurate quantitation of analytes in complex matrices that are gained by coupling a second dimension separation directly to standard LC–MS.
The penultimate presentation is titled “Whole blood Analysis using New Solid Phase Microextraction Devices and Investigation of the Hematocrit Effect,” and will be given by Nathaly Rayes Garces. This talk will present an alternative support material to manufacture SPME devices for bioanalytical applications and the results from an evaluation of the hematocrit effect on SPME extractions from blood.
Finally, Mark Wrona of Waters Corporation will present “Comparison of Travelling Wave IMS-QTof Geometries and Acquisition Modes for Quantitative Analysis.” Wrona will discuss the performance characteristics of current travelling wave-based ion mobility platforms and advances using a novel traveling wave ion mobility time-of-flight geometry to enhance the resolution, sensitivity, and specificity of data for molecules using the properties of m/z and collisional cross section area.
New Study Uses MSPE with GC–MS to Analyze PFCAs in Water
January 20th 2025Scientists from the China University of Sciences combined magnetic solid-phase extraction (MSPE) with gas chromatography–mass spectrometry (GC–MS) to analyze perfluoro carboxylic acids (PFCAs) in different water environments.
The Next Frontier for Mass Spectrometry: Maximizing Ion Utilization
January 20th 2025In this podcast, Daniel DeBord, CTO of MOBILion Systems, describes a new high resolution mass spectrometry approach that promises to increase speed and sensitivity in omics applications. MOBILion recently introduced the PAMAF mode of operation, which stands for parallel accumulation with mobility aligned fragmentation. It substantially increases the fraction of ion used for mass spectrometry analysis by replacing the functionality of the quadrupole with high resolution ion mobility. Listen to learn more about this exciting new development.
A Guide To Finding the Ideal Syringe and Needle
January 20th 2025Hamilton has produced a series of reference guides to assist science professionals in finding the best-suited products and configurations for their applications. The Syringe and Needle Reference Guide provides detailed information on Hamilton Company’s full portfolio of syringes and needles. Everything from cleaning and preventative maintenance to individual part numbers are available for review. It also includes selection charts to help you choose between syringe terminations like cemented needles and luer tips.
The Complexity of Oligonucleotide Separations
January 9th 2025Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.
Oasis or Sand Dune? Isolation of Psychedelic Compounds
January 20th 2025Magic mushrooms, once taboo, have recently experienced a renaissance. This new awakening is partially due to new findings that indicate the effects of psilocybin, and its dephosphorylated cousin psilocin may produce long lasting results for patients who might be struggling with anxiety, depression, alcohol and drug abuse, and post-traumatic stress disorder. Hamilton Company has developed a methodology for the isolation and identification of 5 common psychedelic compounds used in the potential treatment of disease. The PRP-1 HPLC column resin remains stable in the harsh alkaline conditions ideal for better separations.
