The Eastern Analytical Symposium (EAS) supports a Student Research Awards program to recognize students involved in research in the broad field of analytical chemistry. These awards have been expanded to include both graduate and undergraduate students. This year, there are four winners in each category.
The 2022 Graduate Student Research Awardees are Kaylie Kirkwood of North Carolina State University (Nominated by Prof. Erin Baker); Kevan Knizner of North Carolina State University (nominated by Prof. David Muddiman); Samuel Krug of the University of Maryland (nominated by Prof. Maureen Kane); and Lexi McCarthy of The Ohio State University (nominated by Prof. Phillip Grandinetti).
The winners of the 2022 Undergraduate Student Research Award are Quang Minh (Harry) Dang of the University of Richmond (nominated by Prof. Michael Leopold); Olivia Dioli of North Carolina State University (nominated by Prof. David Muddiman); Matthew Giammar of The Ohio State University (nominated by Prof. Philip Grandinetti); and Naiara Munich of Barnard College (nominated by Prof. Lauren Marbella).
Nomination criteria for the awards include excellent grades, appraisals of how the students handle their investigations, their approach, and how they resolve problems and publicly disseminate their work. For more information on nominating a student for 2022, click here.
Modern HPLC Strategies: Improving Retention and Peak Shape for Basic Analytes
August 16th 2024In high-performance liquid chromatography (HPLC), it is common for bases and unreacted ionized silanols on silica-based columns to cause irreproducible retention, broad peaks, and peak tailing when working with basic analytes. David S. Bell, Lead Consultant at ASKkPrime LLC offers innovative HPLC strategies that can help mitigate such issues.
Reliable Separation and Efficient Group-type Quantitation of Total Petroleum Hydrocarbons (TPHs)
September 11th 2024Petroleum contamination from leaking underground storage tanks, for example, is a significant concern for both the environment and human health. Thorough characterization of the contamination is required to form appropriate risk assessments and remediation strategies, but until now, the determination of total petroleum hydrocarbons (TPHs) in soil has typically involved a convoluted and labour-intensive process. In this article, the analysis of TPH in environmental media is simplified using flow-modulated GC×GC–FID with quantitation based on pre-defined compound groupings. This approach overcomes the drawbacks of conventional solvent fractionation approaches, by eliminating the need for sample fractionation and automating data processing workflows.
The Reality Behind Column Insertion Distance
September 10th 2024Column insertion distance is critical to good chromatography. What happens if the column is installed too low in the injection port? Is insertion distance more important when performing split injection or splitless injection? Does the position of the column in the injection port impact reproducibility?
