[Determination of tranexamic acid in essential cosmetics by pre-column derivatization capillary electrophoresis coupled with electrogenerated chemiluminescence detection].

Se pu = Chinese journal of chromatography
-Methylation of tranexamic acid yields an unique derivative, which generates strong co-luminescence signals in the presence of an electrochemiluminescence reagent such as Ru(bpy). Using this principle, we established a highly selective analytical met...

[Determination of 18 phenolic compounds in water by gas chromatography-tandem mass spectrometry coupled with solid phase extraction].

Se pu = Chinese journal of chromatography
At present, the kinds and the hazards of phenolic compounds in water were unclear. Research aimed at methods for the simultaneous detection of multiple phenolic compounds is still in its nascent stages. It is necessary to establish a method for the s...

[Rapid screening and determination of fentanyl and its analogues in drugs by liquid chromatography- quadrupole time-of-flight mass spectrometry].

Se pu = Chinese journal of chromatography
A method based on liquid chromatography coupled with high-resolution quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) was developed for the simultaneous screening and determination of fentanyl and its 26 analogs in liquid and solid powder dru...

[Simultaneous determination of twelve antiepileptic drugs in serum by ultra high performance liquid chromatography-tandem mass spectrometry].

Se pu = Chinese journal of chromatography
A sensitive, high-throughput method was established for the simultaneous determination of 12 antiepileptics in serum by ultra high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The antiepileptics were gabapentin, lamotrigin...

[Determination of 32 polychlorinated biphenyls in aquatic products by gas chromatography-high-resolution mass spectrometry with accelerated solvent extraction-purification simultaneously coupled to isotope internal standard method].

Se pu = Chinese journal of chromatography
Gas chromatography (GC)-high-resolution mass spectrometry (HRMS) with accelerated solvent extraction (ASE)-purification simultaneously coupled to the isotope internal standard method is proposed for the determination of 32 polychlorinated biphenyls (...

[Determination of vitamin K and vitamin K in modulation milk powder by post-column reduction-high performance liquid chromatography].

Se pu = Chinese journal of chromatography
A method for the determination of vitamin K and vitamin K in modulation milk powder was developed by high performance liquid chromatography (HPLC) coupled with post-column reduction. The samples were dissolved in water, lipase hydrolyzed, saponified ...

[Determination of 18 pesticide residues in environmental water by solid phase extraction-ultra performance liquid chromatography-tandem mass spectrometry].

Se pu = Chinese journal of chromatography
A method was developed for the simultaneous determination of 18 pesticide residues in environmental water by solid phase extraction-ultra performance liquid chromatography-tandem mass spectrometry (SPE-UPLC-MS/MS). The samples were purified and enric...

[Determination of diazepam in aquatic products by ultra performance liquid chromatography-tandem mass spectrometry with pass-through solid phase extraction].

Se pu = Chinese journal of chromatography
A method was developed for the determination of diazepam in aquatic products by pass-through solid phase extraction-ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The analyte was extracted with acetonitrile directly an...

[Determination of polycyclic aromatic hydrocarbon metabolites in urine by liquid-liquid extraction-high resolution gas chromatography-high resolution dual-focus magnetic mass spectrometry].

Se pu = Chinese journal of chromatography
A sensitive and accurate method was developed to quantify eight polycyclic aromatic hydrocarbon (PAH) metabolites in human urine by liquid-liquid extraction-high resolution gas chromatography-high resolution dual-focus magnetic mass spectrometry (LLC...

[Simultaneous determination of five baicaleins in healthy product tablets by dispersive solid-phase extraction-high performance liquid chromatography-tandem mass spectrometry].

Se pu = Chinese journal of chromatography
A method based on dispersive solid-phase extraction-high performance liquid chromatography-tandem mass spectrometry (DSPE-HPLC-MS/MS) was developed for the simultaneous determination of five analytes scutellarein, 4'-hydroxywogonin, norwogonin, baica...
