Most chromatographic matrices are based on
Gas chromatography (GC), also sometimes known as gas-liquid chromatography, (GLC), is a separation technique in which the mobile phase is a gas. Gas chromatographic separation is always carried out in a column, which is typically "packed" or "capillary". Packed columns are the routine work horses of gas chromatography, being cheaper and easier to use and often giving ade… WebThey used a higher orthogonal coupling by combining hydrophilic interaction liquid chromatography (HILIC) and reversed-phase (RP) chromatography. Most of the analytes were collected in a small fraction at the beginning of the HILIC column, due to the nonpolar character of the analyzed pesticides, while the polar components of the matrix ...
