Drug addiction is a disease that characterized by compulsion, desire to take different substances permanently or for certain period of time. Numerous negative incidents, such as crimes, work accidents and traffic accidents, are related using illegal substances. Therefore, urine drug cassette tests have become screening tool. However, considering legal consequences test result, the question aris...

This paper explains the development of a quick and easy gas chromatography (GC) approach to identify methamphetamine in urine. research used with mass spectroscopy capillary column TG-5SILMS (5% phenyl methyl siloxane, 30 m x 0.32 25 m). The carrier flow rate was set at 1.0 mL/minute, temperature inlet detector had been 300°C, oven programmed initiate 50°C held for 1.5 minutes before being rais...

An immunoaffinity chromatographic (IAC) method for isolating sulfamethazine (SMZ) from incurred urine samples was developed. This was achieved by (i) generating polyclonal antibodies that recognize equally well SMZ and its major urinary metabolites, (ii) evaluating in an ELISA procedure the influence of methanol, salt and pH on the antigen-antibody interaction in order to determine the optimum ...

A simple and rapid method for the determination of amphetamine, methamphetamine, and their 3,4-methylenedioxy derivatives in urine samples was developed using automated in-tube solid-phase microextraction (SPME) coupled with liquid chromatography-electrospray ionization mass spectrometry (LC-ESI-MS). In-tube SPME is an extraction technique for organic compounds in aqueous samples in which analy...

recently, with increasing public awareness of food safety, developments of some valid and rapidly analytical methods are required for the determination of residual pesticides in crops.this study was conducted on validation of a reliable, accurate and precise method for multi analysis of pesticides residue in melon as a main fruit in iranian food basket. a reliable, and valid method based on spi...

The initial fixation strengths of two spiked-washer designs were evaluated using human femurs and fascia lata tissue. Fascia lata was attached to the femur using the fixation devices, and then each femur-washer-fascia lata complex was loaded in tension to failure. Load-elongation curves were recorded, the initial failure load, initial failure displacement, stiffness, ultimate load, and ultimate...

a capillary electrophoresis method was used for assay of some degradation products of carvedilol. the optimized parameters were as; running buffer 80 mm acetate dissolved in methanol/ethanol mixture (65:35 v/v), applied voltage of 19 kv, temperature is 20 ºc and the wavelength range of 200-350 nm. the results indicate that the proposed ce method could effectively separate carvedilol from its de...
