Practical 2 – UV-Visible Spectroscopy Iron in dietary supplements Introduction UV-Visible spectroscopy is an analytical technique involving measurement of the UV-visible light absorbed by substances, and is therefore commonly used for determining the concentration of a substance in a sample. Many substances absorb energies of particular wavelengths, while transmitting energy of other wavelengths. A UV-visible spectrum is produced when photons that are present in this particular region of

as a reference that I understand the concept and calculation of the lab and will send another lab explaining the errors. AA1 - Varian Spectra AA 200 Experiments INTRODUCTION Concept: Atomic absorption spectroscopy (AAS) is a spectra analytical procedure for the quantitative determination of chemical elements employing the absorption of optical radiation (light) by free atoms. It is capable of measuring the concentrations of a wide variety of element in sample. In AAS method measures the light

to copper poisoning which was found to leach from a pot into the soup under high heat and acidic condition. It was also suspected that an organic compound was present in the soup which enhanced the absorption of copper in consumer. Hence, as an analytical chemist, we have to use UV to determine the actual concentration of copper standards and blank using external calibration standards. The result of the test solution was measured by comparing it with the calibration of copper. Introduction The

demonstrate the software and the procedures for preparing the instrument. Each group will run a series of calibration standards to generate a calibration curves. The concentrations are given below. Then, one of the "unknown" samples (A or B) should be run. The printer will generate a report of the concentration of Zinc in the sample. We have to be sure which sample we are used. Our laboratory report should describe the functions of the AAS and describe the procedures for preparing the instrument for

indicate when mobilization of minerals from the spongiosa is accompanied by mobilization from the shaft. Further, the balance over a whole lactation is often small in relation to the total quantities of materials analyzed and may be close to the analytical errors of the methods when the diet given is rich in minerals. The present observations may find some application in the determination of certain mineral requirements of lactation. Because the losses of Ca and P are unavoidable, involving the gradual
