The objective of the study was to maximize throughput without introducing a significant number of additional chromatographic co-elutions not separable by deconvolution, whilst transitioning from a standard 30 m column to a 15 m column.
LECO's proprietary deconvolution software, embodied as NonTarget DeconvolutionTM, was leveraged to maintain exceptional peak fidelity of the qualitative analysis, while the Target Analyte Find feature was utilized for robust quantitation and to establish method detection limits for organonitrogen pesticides spiked in QuEChERS strawberry extracts.
Identifying Non-Intentionally Added Substances (NIAS) in Food Contact MaterialsPoster
Concern about the safety of food products has increased dramatically with intentionally and non-intentionally added substances (NIAS) used in packaging being of particular interest. APGC and high resolution MS together with a workflow driven process was used to identify unknown compounds in packaging.READ MORE
Human exposure to cyanotoxins: Exploring in vitro detoxification using atmospheric cold plasma treatment to protect human healthPoster
Recently, there have been increases in freshwater harmful algal blooms. There is therefore a need to try and effectively detoxify drinking water contaminated with cyanotoxins to safeguard human health by use of new and novel techniques.READ MORE
Partial characterization of Plasmodium falciparum protein kinase ABCK2 (PfABCK2)Poster
PfABCk2 gene is ligated into pET21a+ vector with His-tag at C-terminus and transformed into BL-21 (DE3) competent cells that are verified through Miniprep and DNA sequencing. Furthermore, this gene construct is utilized to heterologous express this protein with IPTG and afterwards purified the recombinant protein kinase using nickel affinity chromatography as shown on 10% SDS-PAGE with the expected 36 kDa protein band.READ MORE
