Ionic liquids as matrixes for matrix-assisted laser desorption/ionization mass spectrometry.
Whether their high solubalizing power, negligible vapor pressure, and broad liquid temperature range are advantageous if they are used as matrixes for UV-MALDI is examined.
Ionic liquids in analytical chemistry.
Characterizing ionic liquids on the basis of multiple solvation interactions.
A linear free energy approach is used to characterize 17 RTILs on the basis of their distinct multiple solvation interactions with probe solute molecules and provides data that can be used to help identify the interactions and properties that are important for specific chemical applications.
Enantiomeric Composition of Nicotine in Smokeless Tobacco, Medicinal Products, and Commercial Reagents
The enantiomeric composition of nicotine in 18 smokeless tobaccos, 3 strains of tobacco leaf, 8 pharmaceutical products, and 4 commercial reagents was determined and it appears that (R)-(+)-nicotine may be considered one of the five most common alkaloids in tobacco products.
Structure and properties of high stability geminal dicationic ionic liquids.
Thirty-nine geminal dicationic ILs were synthesized and characterized in terms of their surface tensions, densities, melting points, refractive indices, viscosities, and miscibilities with a polar
Comparison of Pure Nicotine- and Smokeless Tobacco Extract-Induced Toxicities and Oxidative Stress
Results indicated that nicotine is less toxic than smokeless tobacco extract that contained the same amount of nicotine, and the generation of reactive oxygen species, following treatment with tobacco extract and nicotine, was assessed.
Rapid CE microbial assays for consumer products that contain active bacteria.
A specific capillary electrophoresis technique is used to identify and quantitate Lactobacillus acidophilus in both pill and syrup health products as well as Bifidobacterium infantis in a powdered formula supplement.
Degradation study of carnosic acid, carnosol, rosmarinic acid, and rosemary extract (Rosmarinus officinalis L.) assessed using HPLC.
The degradation of rosemary extract in fish oil was investigated, and much slower rates of degradation were observed for carnosic acid, though it does so at least in part at the cost of its own degradation in the mixture of the three antioxidants.
