Acid in Human Determination Urine
An ion pair reversed phase HPLC method for the determination of clavulanic acid has been developed. Since clavulanic acid had poor absorption O,mas 201 nm in water) in a UVregion suitable for HPLC detection, the detectability was enhanced by bathochromic shift of )maa due to solvent effect. The shifts of 2ma.., were measured with the solutions containing clavulanic acid, tetrabutylammonium brom...
متن کاملApplication of Ion Mobility Spectrometry for Determination of Morphine in Human Urine
In this study, a rapid, simple and sensitive ion mobility spectrometry (IMS) method with corona discharge as ionization source was described for the morphine determination in human urine. Morphine was extracted and purified from urine samples using solid phase extraction procedure with C18 column. It can offer the clean extracts which no extra peaks were observed in IMS. Under operating experim...
متن کاملExtraction and Determination of Cyproheptadine in Human Urine by DLLME-HPLC Method
Novel dispersive liquid-liquid microextraction (DLLME), coupled with high performance liquid chromatography with photodiode array detection (HPLC-DAD) has been applied for the extraction and determination of cyproheptadine (CPH), an antihistamine, in human urine samples. In this method, 0.6 mL of acetonitrile (disperser solvent) containing 30 µL of carbon tetrachloride (extraction solvent) was ...

متن کاملAn improved method for Organic Bound Tritium (OBT) determination in urine samples.
The Organic Bound Tritium (OBT) amount in the body may induce changes in the evaluation of the internal exposure to tritium, due to its different retention time relative to HTO. OBT measurements for urine are not performed routinely, mainly because of the lengthy work needed in preparation of the samples, when using the standard oxygen combustion method. A simpler and more rapid method based on...
