Introduction to Radiocarbon Determination by the Accelerator Mass Spectrometry Method
There are three principal isotopes of carbon which occur naturally C, C (both stable) and C (unstable or radioactive). These isotopes are present in the following amounts C 98.89%, C 1.11%, and C 0.00000000010%. Thus, one carbon-14 atom exists in nature for every 1,000,000,000,000 or (1 in a trillion) carbon-12 atoms in living material. The radiocarbon method is based on the rate of decay of th...
متن کاملA quick and Sensitive Liquid Chromatography–tandem Mass Spectrometry (LC-MS) Method for the Determination of Enalapril and Enalaprilat in Human Plasma: Application to a Bioequivalence Study
A rapid and sensitive liquid chromatography–tandem mass spectrometry (LC-MS) method for the estimation of enalapril and enalaprilat in human plasma. Detection of analytes was achieved by tandem mass spectrometry with electrospray ionization (ESI) interface in positive ion mode was operated under the multiple-reaction monitoring mode. Sample pretreatment involved in a one-step protein precipitat...
متن کاملDevelopment and Application of a Validated Liquid Chromatography-Mass Spectrometry Method for the Determination of Dexchlorpheniramine Maleate in Human Plasma
A convenient liquid chromatographic-single Quadrupole mass spectrometric (LC-MS) method was developed and validated for dexchlorpheniramine maleate (INN name: chlorphenamine) determination in human plasma. The need for just a single liquid-liquid extraction with ethyl acetate and being highly sensitive were the advantages of this method. The linearity was also excellent over the range of 1...
متن کاملDetermination of diclofenac concentrations in human plasma using a sensitive gas chromatography mass spectrometry method
BACKGROUND A gas chromatography mass spectrometry (GCMS) method for the determination of diclofenac in human plasma has been developed and validated. RESULTS This method utilizes hexane which is a relatively less toxic extraction solvent compared to heptane and benzene. In addition, phosphoric acid and acetone were added to the samples as deproteination agents, which increased the recovery of...
متن کاملAccelerator mass spectrometry: ultra-sensitive analysis for global science
Accelerator mass spectrometry (AMS) is the analytical technique of choice for the detection of long-lived radionuclides that cannot be practically analysed with decay counting or conventional mass spectrometry. AMS has been used for the analysis of C, Be, Cl and other cosmogenic radionuclides in archaeology, geology and environmental science. In addition, the ultrasensitivity of AMS is being ap...
