Chemometric assisted determination of 16 PAHs in water samples by ultrasonic assisted emulsification microextraction followed by fast high-performance liquid chromatography with diode array detector

On the co-elution of benzo[a]pyrene and dibenzo[a,l]pyrene in chromatographic fractions and their unambiguous determination in tobacco extracts via laser-excited time resolved Shpol'skii spectroscopy

“…With minor modications, the HPLC option of Method 610 has proven useful for the determination of EPA-PAHs in a wide variety of samples. These include hair; 6 food; [7][8][9] soil and sediment; [10][11][12][13] water; [14][15][16] tissue; 17,18 drugs; 19 oil; 20,21 air; 22 saliva; 23 and tobacco products. [24][25][26][27][28] Herein, we apply the HPLC Method 610 to the analysis of PAH isomers of MM 302 Da.…”

A systematic study on the effect of different error structures on pseudo‐univariate and multivariate figures of merit

“…[35][36][37] AFOM values for classical univariate calibration, where the signal has to be sufficiently selective for the relevant analyte, are clearly defined and have often been discussed in the documentation for both noise-free and data with non-homoscedastic error data. Although many works have reported using pseudo-univariate and multivariate analytical figures of merit, [37][38][39][40][41][42][43] there is no comprehensive comparison for using different types of MCR-ALS and different strategies for calculating figures of merit.…”

Determination of Concentration for Some Priority Substances in Paddy Fields of Ergene River, Meriç River, and Yenikarpuzlu Dam, Turkey

“…The extensively used high sensitivity analytical techniques for the determination of EN and PAHs at low concentrations in environmental samples are GC-MS [6,8,20,21], HPLC-MS [10,22]. The separation and preconcentration techniques for pesticides are solid phase extraction (SPE) [21,23,24], solid phase micro extraction (SPME) [21,22,25] and sonication [22,26], which are used to solve these problems in analysis of EN and PAHs.…”
