To screen such samples means to analyze hundreds of polar, nonpolar, and low-volatile sub-stances simultaneously. 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...
The non-polar heterocyclic amines 3-amino-1,4-dimethyl-5H-pyrido(4,3-b)indole and 3-amino-1-methyl-5H-pyrido(4,3-b)indole were detected in the range of 0.5-7.4 ng/g in most foods cooked at 225 degree C, and also in meat sauce prepared at 200 and 175 degree C. The other ...
Unique Selectivity for the Separation of Polar and nonpolar Analytes Low silanol activity for excellent peak shape with basic compounds High selectivity for hydrophobic aromatic molecules Compatible with 100% aqueous mobile phase Extremely low bleed, fully compatible with MS ...

What Does “Polar” and “Non-Polar” Mean? The Distinction Between “Protic” And “Aprotic” Solvents Nonpolar Solvents: A Table “Borderline” Polar Aprotic Solvents Polar Aprotic Solvents: A Table Polar Protic Solvents: A Table Notes
The retention behavior of ten polar aromatic organic compounds containing alkyl, hydroxyl, amino, and carboxylic acid groups was studied in nonpolar—nonpolar liquid chromatography. A μ Bondapak C 18 column was used as the stationary phase, and n-hexane was used as the mobile phase to which ...
