Mapping Elemental Nutrient and Surface Treatment Distribution in Produce
Poster Apr 03, 2017
Nutritionists address the benefits of obtaining elemental nutrients directly from food, especially fresh, uncontaminated produce. This project will demonstrate non-destructive techniques developed to visually map distribution and relative abundance of elemental nutrients and treatments of produce.
Three types of X-ray fluorescence (XRF) spectrometers were used. All provided user control of atmosphere, power, filters and collimators for optimization of elemental analysis in various matrices. They also provided qualitative and quantitative XRF elemental analysis software.
Data presented will include maps of elemental nutrient rich locations in fruit as well as distribution of elemental surface treatments for preservation of produce from farm to market. The various methods utilized for data collection will be described. Future research planned includes monitoring elementall nutrient distribution changes over time and with different storage conditions.
Overcoming the Challenges of Analysing Ionic Polar Pesticides in FoodPoster
Here, the novel application of the Waters’ Torus DEA column is presented, showing the improved performance of a UPLC-MS/MS method for the underivatised
analysis of glyphosate and a selection of other anionic pesticides.
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
