Fourteen cooked dishes with their corresponding pan residues were analysed for polar and non-polar heterocyclic amines using HPLC. The choice of foods, including beef, pork, poultry, game, fish, egg and sausages, was based on an investigation of an elderly population in Stockholm participating in...

African green leafy vegetables (GLVs), commonly consumed by these populations and rich in bioactive compounds, may improve the antioxidant status. The aim of this study was to measure the antioxidant capacity using complementary assays (DPPH, FRAP, ABTS, ORAC and NO scavenging) in polar and non...
Non polar solventscontain bonds between atoms with similar electronegativities, such as carbon and hydrogen (think hydrocarbons, such as gasoline). Bonds between atoms with similar electronegativities will lack partial charges; it’s this absence of charge which makes these molecules “non-polar”....

Although the analysis of polar compounds is sometimes difficult using gas chromatography (GC), it is a generally applied chromatographic method. Improving the vaporization process of polar compounds in GC by derivatiza-tion: A precondition for GC determina-tion of organic compounds is nondestruc-...
Enhancement of Retention by Ion-Pair Formation in Liquid Chromatography with Non-polar Stationary Phases In ion-pair reversed-phase chromatography, the retention of Ionized analytes on a nonpolar bonded stationary phase Is enhanced by the presence of a "hydrophobic" counterion (hetaeron) In the mobil...
Lunar polar volatiles, such as water ice, are essential lunar exploration objects. The conceptual design for China’s Chang’E-7 lunar exploration mission to the South Pole was proposed. The mission comprises an orbiter, a lander, a rover
