• SPME (solid phase micro extraction; s. ref 1) is an analyte enrichment method commonly used for the analysis of gaseous or liquid samples in conjunction with gas chromatography/mass spectrometry.
• An important part of method optimization is the selection of the appropriate fiber. This normally requires the manual changing of fibers. In practice, little fiber optimization work is actually done and most methods used rely on analyst experience.
• A new type of robotic sample handler allows for the automatic change of tools. This opens the possibility for the automated selection of the best suited SPME fiber as well as the optimization of key process parameters.
Using Remote Sensing Methodologies to Combat Schistosomiasis in Northern SenegalPoster
Schistosomiasis is associated with poverty, a lack of clean water and sanitation and is is transmitted through snail vector. Remote sensing methodologies were used to identify types of vegetation that are significantly associated with snail presence as previous studies had shown that removal of certain aquatic vegetation decreased the prevalence of schistosomiasis in nearby villages.READ MORE
