Abstract An ion-pair liquid chromatography-mass spectrometry/mass spectrometry method was developed for the determination of chlormequat in fruit samples. A solid-phase extraction cleanup procedure with C18 cartridges was used. Sample preparation was simple and the achieved detection limit (0.03 mg/kg) and quantitation limit (0.08 mg/kg) were below the maximum residue levels legislated by the European Union. The chromatographic separation was performed by using a C8 column and heptafluorobutyric acid as ion pair reagent. The detection was conducted with an electrospray source and an ion trap a

Abstract Alliin and allicin in garlic and their products are determined simultaneously by ion-pair reversedphase liquid chromatography (LC) with diode array UV detection. Alliin is extracted from fresh garlic, purified by ion-exchange chromatography, and appliedas external standard. Allicin is generated enzymatically from alliin, confirmed by LC, and applied as external standard. Compounds areextracted from samples with water and chromatographed on an octadecylsilane column with gradient elution from 0.01 M phosphate buffer (pH 2.5) with 5 mM heptanesulfonic acid (A) to 0.01 M phosphate buffer

Abstract We describe a chromatographic procedure for sensitive (2.0 mumol/L), specific quantification of vanillylmandelic acid (VMA) in urine with iso-VMA as an internal standard. After rapid extraction from urine, the VMA is determined by isocratic reversed-phase ion-pair chromatography on a bonded C8 column and detection of the native fluorescence on excitation at 285 nm. The fluorescence signal is quite dependent on the pH of the mobile phase. Results by the method vary linearly with VMA concentration up to 320 mumol/L and correlate well (r = 0.9880) with those obtained by conventional ultr

The ion chromatographic method was developed to determine tetrafluoroborate ion (BF4-) in different types of water using ion pair liquid-liquid dispersive microextraction. Tetrafluoroborate was extracted into an organic phase (1,2-dichloroethane) as an ion pair with a tetrabutylammonium cation (TBA+). The most complete formation of [(ТBА+)(BF4-)] was observed at ion-pair reagent concentration of at least 5 mmol L-1 (C(BF4-) ≤ 1mg L-1). Ultrasonic irradiation was used to disperse the extractant. The achieved concentration factor (K) was 29±3, and the degree of extraction (R) was 50±5%. The limi

Strong acidic drugs are a class of chemical compounds that normally have high hydrophilicity and large negative charges, such as organophosphatic compounds and organosulphonic compounds. This review focuses on sample preparation and separation methods for this group of compounds in biological matrices in recent years. A wide range of separation techniques, especially chromatographic method, are presented and critically discussed, which include liquid chromatography (e.g., ion-pair and ion-exchange chromatography), capillary electrophoresis (CE), and other types.
