Method B (n=7): 0.44卤0.02 h (p< 0.05). No hepatotoxicity was observed during treatment in TDM outpatients who underwent rapid VRCZ measurement. CONCLUSION. It is suggested that rapid determination of blood concentration of VRCZ by HPLC-UV will be an effective tool for TDM implementation ...
Additionally, a material reference characteristic chromatographic method based on HPLC-UV-ELSD was established to precisely determine its similarity range and peak attribution of its characteristic chromatographic pattern. This method, combined with an analysis of the quantitative transfer of material groups ...
There is no chromophore in the TA molecule enabling direct analysis by UV-visible absorption spectrophotometry; this has also hindered development of an analytical HPLC-UV method for determination of TA, by excluding use of UV or ?uorescence detection. Chromophores or ?uorophores reported for ...
