In many countries, thiabendazole is used as a fungicide to prevent the decay of food and lengthen storage periods. However, in Korea, unauthorised does not have standards or specifications for use additive. this study, simple analytical method was developed validated using HPLC–PDA detect foods frequently consumed South Korea. The calibration curve obtained samples solid liquid containing banan...

BACKGROUND The addition of a calibration curve with every run is both time-consuming and expensive for clinical mass spectrometry assays. We present alternative calibration strategies that eliminate the need for a calibration curve except as required by laboratory regulations. METHODS We measured serum nortriptyline concentrations prospectively in 68 patients on 16 days over a 2-month period ...

Introduction: In radiotherapy treatment planning system (TPS), basic input is the data from computed tomography (CT) scan, which takes into account the effect of inhomogeneities in dose calculations. Measurement of CT numbers may be affected by scanner-specific parameters. Therefore, it is important to verify the effect of different CT scanning protocols on Hounsfield unit (HU) and its impact o...

in this study, a rapid and simple method based on graphite furnace atomic absorption spectrometry (gfaas) is described for direct determination of arsenic in potassium citrate tablet samples. pyrolytic graphite tubes were used as atomizers. nickel nitrate was used as chemical modifier. the ashing and atomization temperature and the concentration of modifier were also optimized. the detection li...

a method for the simultaneous determination of sulfamethoxazole (smx) and trimethoprim (tmp), based on a direct determination of smx after diazotization and coupling with 2-naphthol by visible spectrophotometry and an indirect determination of tmp in the uv region by difference was developed. by the suggested procedure, it was possible to analyze smx and tmp in pharmaceutical preparations witho...

soil conservation service curve number method (scs-cn) is a widely applied technique for predicting direct runoff from rainfall has been used around the world. in this study, the curve number maps and entry physical model data of kheyrud basin to hec-hms model, the hec-geohms extension in arcgis software and google earth satellite images were used. in addition to the statistical analysis of sur...

Reversed phase-HPLC separation of capsaicin and dihydrocapsaicin in some hot chilli varieties was achieved using photodiode array (PDA) detector. Under optimum conditions, their analytical figures of merit for the HPLC method were validated. The linearity range of calibration curve was 1.0-25 μg/mL with multiple determination coefficients higher than 0.995. Limits of detection and quantitation ...

Abstract A sensitive and accurate high performance liquid chromatography method utilizing ultraviolet/visible light detection (HPLC-UV) for the quantification of Ribociclib in Spiked Human Plasma by HPLC-UV was developed validated. (RCB) internal standard (IS), Trifluridine, were first extracted from plasma samples a simple Protein Precipitation extraction using Acetonitrile. concentration RCB ...
