Scarfe, G.B.; Clayton, E.; Wilson, I.D.; Nicholson, J.K., 2000: Identification and quantification of metabolites of 2,3,5,6-tetrafluoro-4-trifluoromethylaniline in rat urine using 19F nuclear magnetic resonance spectroscopy, high-performance liquid chromatography-nuclear magnetic resonance spectroscopy and high-performance liquid chromatography-mass spectrometry. The urinary excretion profile and identity of the metabolites of 2,3,5,6-tetrafluoro-4-triflouromethylaniline, following i.p. administration to the rat at 50 mg kg(-1), were determined using a combination of 19F-NMR, HPLC-NMR and HPLC-MS. A total...

Bringmann, G.; Wohlfarth, M.; Heubes, M., 2001: Observation of exchangeable protons by high-performance liquid chromatography-nuclear magnetic resonance spectroscopy and high-performance liquid chromatography-electrospray ionization mass spectrometry: a useful tool for the hyphenated analysis of natural products. The first high-performance liquid chromatography-nuclear magnetic resonance (HPLC-NMR) investigation of exchangeable protons of low-molecular-mass natural products is reported. Model alkaloids or crude plant extracts were dissolved in 2H2O-1H2O-Me...

Grynbaum, M.-David; Meyer, C.; Putzbach, K.; Rehbein, J.; Albert, K., 2007: Application of polymer based stationary phases in high performance liquid chromatography and capillary high performance liquid chromatography hyphenated to microcoil H-1 nuclear magnetic resonance spectroscopy. The increased demand for chromatographic materials that are able to achieve a fast separation of large quantities of structure analogues is a great challenge. It is known that polymer based chromatographic materials have a higher loadability, com...

The increased demand for chromatographic materials that are able to achieve a fast separation of large quantities of structure analogues is a great challenge. It is known that polymer based chromatographic materials have a higher loadability, comp...

Xin, Y-Yang.; Deng, A-Jun.; Du, G-Hua.; Zhang, J-Lan.; Qin, H-Lin., 2010: Fingerprinting analysis of Saposhnikovia divaricata using 1H nuclear magnetic resonance spectroscopy and high performance liquid chromatography. The (1)H nuclear magnetic resonance ((1)H NMR) fingerprints of fractionated non-polar and polar extracts (control substance for plant drug [CSPD] A and B) from the roots of 12 specimens of Saposhnikovia divaricata (Turcz.) Schischk were achieved w...

Li, J.; Wang, Y.; Fenwick, A.; Clayton, T.Andrew.; Lau, Y.Y.K.; Legido-Quigley, C.; Lindon, J.C.; Utzinger, Jürg.; Holmes, E., 2007: A high-performance liquid chromatography and nuclear magnetic resonance spectroscopy-based analysis of commercially available praziquantel tablets. The amount of active ingredient in 20 commercially sourced batches of praziquantel (PZQ) tablets was determined using a high-performance liquid chromatography-ultraviolet (HPLC-UV) assay in conjunction with an anthentic, lot of PZQ powder. The gen...

The (1)H nuclear magnetic resonance ((1)H NMR) fingerprints of fractionated non-polar extracts (control substance for a plant drug (CSPD) A) from Rhizoma chuanxiong, the rhizomes of Ligusticum chuanxiong Hort., of seven specimens from different so...

Skogsberg, U.; Händel, H.; Sanchez, D.; Albert, K., 2004: Comparisons of the interactions between two analytes and two structurally similar chiral stationary phases using high-performance liquid chromatography, suspended-state high-resolution magic angle spinning nuclear magnetic resonance and solid-state nuclear magnetic resonance spectroscopy. A study of the retention behaviour of the enantiomers (R)- and (S)-1,1'-binaphthyl-2,2'-diol as well as (+) and (-)-O,O'-dibenzoyl-tartaric acid was performed using the two chiral stationary phases (CSPs) Kromasil-DMB and Kromasil-T...

Preiss, A.; Levsen, K.; Humpfer, E.; Spraul, M., 1996: Application of high-field proton nuclear magnetic resonance spectroscopy for the analysis of explosives and related compounds in groundwater samples - a comparison with the high-performance liquid chromatography method. High-field proton nuclear magnetic resonance (1H-NMR) spectroscopy was applied to the analysis of nitroaromatics and nitramines in ammunition waste water. The 1H-chemical shifts data of a variety of reference compounds are presented. Three groundw...
