SFC-UV determination of diflubenzuron residues, teflubenzuron and triflumuron in apple and pear pulps for baby food

Development and application of a method for analysis of lufenuron in wheat flour by gas chromatography–mass spectrometry and confirmation of bio-efficacy against Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae)

“…Alternative methods such as ultraviolet (UV) determinations have also been used for the detection of BPU residues. However, low sensitivity and specificity due to the lack of sufficient discrimination of a signal and the matrix noise was the serious drawback of these methods [9][10][11]. These methods do not directly appear to be applicable to the analysis of lufenuron in a complex matrix like wheat flour.…”

Coupled‐column liquid chromatography method with photochemically induced derivatization for the direct determination of benzoylureas in vegetables

“…In all cases, these LODs and LOQs were significantly lower than those reported by other techniques without column switching mode, such as GC-ECD [37], LC-UV [18,20,21] or PIF [38,39] and are in the same order as those obtained by LC-PIF-FD [22] and LC-MS [23][24][25], using a SPE step in all cases.…”

“…Benzoylurea residues are generally analyzed by LC using UV [18][19][20][21], FD [22], or MS detection [23][24][25]. Because of their high polarity and poor detectability using any kind of detector, these methodologies require considerable effort in sample preparation steps such as extraction, concentration, and clean-up techniques.…”

Gc-Msを用いたシロアリ中のクロルフルアズロンの簡便かつ高感度な定量分析

“…Some of the published studies dealt with measurement of a single BPU, [13][14][15][16] whereas others involved measurements of residues of multiple BPUs. [17][18][19][20][21][22] Generally, analyses of BPUs have been accomplished by high performance liquid chromatography (HPLC) in combination with ultraviolet, 14) diode array detection (DAD), 23) mass spectrometry (MS), 13) and tandem mass spectrometry 24) detection systems. Alternative methods, such as gas chromatography (GC) coupled with electron-capture detection (ECD) 15) or mass spectrometry (MS), 16) have also been applied to screen BPUs.…”
