Search on ruggedness of fast gas chromatography–mass spectrometry in pesticide residues analysis

Comparison of sample preparation methods combined with fast gas chromatography – mass spectrometry for ultratrace analysis of pesticide residues in baby food

“…The 0.15 mm id columns allow more flexibility in loadability, sample introduction (flow rate), and operation when compared to 0.10 mm id columns [11]. Moreover, the ruggedness of 0.15 mm id columns was shown to be very good in the analysis of pesticide residues in plant matrix [9]. Several ways to reduction of matrix effects on the injector and column site were practiced [2,9,12,13] from Agilent Technologies (Avondale, PA, USA).…”

“…Microbore chromatographic column CP-Sil 8 CB (Varian, Middelburg, The Netherlands) with 5% diphenyl 95% dimethylsiloxane stationary phase 15 m60.15 mm id60.15 lm was utilized. It was connected to a nonpolar deactivated precolumn (1 m60.32 mm id) for focusation purposes and better ruggedness of the chromatographic system [9,13]. Constant pressure mode 363.5 kPa was used until the elution of the last analyte (etofenprox, 7.90 min); additional pressure ramp (1000 kPa/min, 685 kPa) was used to speed up elution of higher boiling matrix coextractives.…”

“…Our recent studies proved that the connection of fast GC utilizing microbore column (with id of 0.15 mm) with a common bench top quadrupole mass spectrometer provides efficient separation of 18 studied pesticides from the apple matrix components [2], sufficient number of data-points acquired for the proper peak shape reconstruction and good repeatability of peak areas in SIM mode, and the good overall system ruggedness after repeated matrix injections [8,9].…”

Rapid analysis of food products by means of high speed gas chromatography

“…In the field of contaminant narrow-bore column fast GC work (pesticides, polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs)) a total of 12 studies have been reported [10,45,[56][57][58][59][60][61][62][63][64][65] (Table 1 also reports the use of a resistively heated short conventional column in fast GC pesticide analysis [11]). The feasibility of narrow-bore fast GC for the determination of trace amounts of food contaminants has been demonstrated by a series of studies: a rather thorough study on fast GC-TOF-MS (with a 5 m60.1 mm60.1 lm apolar column), exploited for the determination of organic microcontaminants in spiked water (a river sample) and tea, has been reported by Vreuls et al [56].…”
