Abstract ▼ AI-Helper

This study was performed to apply the more rapid and accurate sample preparation, and the high selectivity and sensitivity of the analyte detection by gas chromatography-triple quadrupole mass spectrometry (GC-MS/MS). QuEChERS (quick, easy, cheap, effective, rugged and safe) method was validated for 49 agrochemicals in the CORESTA Agrochemical Advisory Committee guide and amenable to GC-MS/MS determination. In QuEChERS method, the effects of sorbents (PSA, $C_{18}$ and GCB) and matrix of the analytes in tobacco types (flue-cured, burley and oriental) were investigated. MS/MS acquisition provided high specificity and selectivity for agrochemicals and low limit of quantification. QuEChERS by using PSA alone and the matrix-matched standards gave good recoveries and RSD values in three types of tobaccos. QuEChERS method was no needed to be complex clean-up procedure and would be used as the fast and easy method for agrochemical residue analysis in tobacco.

제안 방법

GC-MS/MS analysis was carried out on a Varian 3800 gas chromatograph/1200L triple quadrupole mass spectrometer equipped with a split/splitless injector and CombiPAL autosampler (CTC Analytics, USA). The data system contains all of the software required for calibration, collection of GC/MS spectra and data processing for qualitative and quantitative analysis.
5, 1 ug/g for each agrochemical. The extraction procedure was performed as the sample preparation method.
To optimize MS/MS conditions, fragmentation of agrochemicals was triple quadrupole mass spectrometer performed. MS, in the selected ion monitoring and full scanning mode, could not avoid matrix interference.

대상 데이터

Recovery tests carried out 3 spiking levels and 3 replicates. A solution of analytes in acetone was spiked to tobacco to achieve a concentration of 0.
Three types of tobacco, flue-cured (BIO, Korea), burley (BIT, Korea) and oriental (Basma, Greece) were used in this study.

이론/모형

Therefore this study was performed to apply the more rapid and accurate sample preparation of agrochemical residues in tobacco by using QuEChERS method. Also the purpose of 나廿s study was to apply triple quadrupole mass spectrometry (MS/MS) for the high selectivity and sensitivity detection of analytes.
