“…Several empirical and mechanical retention models have been proposed to take into account the presence of modifiers in micellar mobile phases [22][23][24][25]. The models allowed to develop optimization procedures which can be used to find quickly the best surfactant concentration and modifier proportion in a micellar mobile phase that will give the optimal resolution in a particular situation [26][27][28][29][30].…”

“…These mobile phases are appropriate for both hydrophobic and hydrophilic analytes, thereby covering a wide range of compounds, as nutrients [3][4][5][6][7][8], drugs [9][10][11][12][13][14][15][16], additives [17,18] and toxics [19][20][21][22][23][24][25][26][27]. The conditions can even be optimized to separate different analytes in the same run [4][5][6][10][11][12][13][14][15][17][18][19]24,27]. Another advantage is the use of micellar solutions as the solvent in a matrix, as hydrophobic compounds are also solubilized due to their interactions with the organic environment inside the micelle.…”

Validation of Micellar LC-Based Methods Applied to Analyze Foodstuffs

The validation of several micellar LC-based analytical methodologies was described. These methods were able to quantify quinolones in fish from fisheries, hydroxytyrosol in olive extracts and biogenic amines in anchovy sauce. The validation was performed following the requirements of official guides to provide more reliability. Two guides suggested by renowned institution are described: US FDA Guidance for Industry and EU Regulation 2002/657/EC Decision. The appropriate guide was used for each method, depending of the analyte, the matrix and the scope of sample. The calculated validation parameters were those proposed by the guide: selectivity, calibration range, linearity, LOD and LOQ, inter- and intra-day accuracy and precision, limit of decision, detection capability, robustness, recovery and stability. The methodologies were successfully validated by the selected guideline, indicating their suitability to be applied to analysis of real samples, proven to be useful to its intended purpose.

“…The acidic mobile phase was obtained by acidifying the micellar mobile phase with TFA to pH value 2.7. Our previous works [34,35] and preliminary experiments showed that the mobile phase composition should be 0.075 mol/L SDS and 1.5% v/v 1-PeOH.…”

Original PaperComparison of C18 silica bonded phases selectivity in micellar liquid chromatographyThe paper describes a new test designed in micellar LC (MLC) to compare the commercial C18 stationary phase properties. This test provides the total hydrophobicity, hydrophilicity, steric selectivity, hydrogen bonding, and ion-exchange capacity properties calculation of the ODS stationary phases. Both the test compounds and chromatographic separation conditions choice for column characterization in MLC are detailed. The chromatographic performance of several stationary phases that are used in MLC was evaluated with specific chromatographic test comprising nine test compounds, possessing different physico-chemical properties, which were injected on different supports with two micellar mobile phases: one at pH 7.0 (0.075 mol/L SDS and 1.5% v/v 1-pentanol), and other at pH 2.7 (0.075 mol/L SDS and 1.5% v/v 1-pentanol adjusted to pH by TFA). Fundamental column chromatographic properties were obtained under these conditions and were treated by hierarchical cluster analysis. From the results of cluster analysis, two closely related groups of columns are distinguished, and it was shown that the chosen column characteristic parameters allow characterizing both sorbent and micellar chromatographic system properties. Eleven columns were analyzed by this test, which allows a comparison of columns with the aim of the selection of suitable and analogous column for the analysis with MLC.
