Iodine Absorption Cells Purity Testing
This article deals with the evaluation of the chemical purity of iodine-filled absorption cells and the optical frequency references used for the frequency locking of laser standards. We summarize the recent trends and progress in absorption cell technology and we focus on methods for iodine cell purity testing. We compare two independent experimental systems based on the laser-induced fluoresc...
متن کاملCu2ZnSnS4 absorption layers with controlled phase purity
We report the synthesis and characterization of Cu2ZnSnS4 (CZTS) with controlled phase purity. The precursor was first prepared using sequential electrodeposition of Cu, Zn, and Sn in different orders. The Cu/(Sn+Zn) ratio in each stacking order was also varied. The precursor was subjected to annealing at 200°C and sulfurization at 500°C in a 5%-H2S/Ar atmosphere for the formation of CZTS. The ...
متن کاملAbsorption and Fluorescence of Molecular Iodine
The UV-Vis absorption spectrum and LIF emission spectrum of I2 were found for the purpose of gaining information about the energy of the ground X( 1 Σg + ) and excited B( 3 Π0u + ) states. This information was compared to information obtained from the Gaussian program which uses quantum mechanical calculations and numerical approximations to predict electronic energy levels. The iodine molecule...
متن کاملPreparation and purity determination of radiolabeled taxol and evaluation of its absorption in murine melanoma
Aim and Background:Taxol is a known substrate for P-glycoprotein, which induces drug resistance to cancerous cells. Therefore radiolabeled taxol can be a suitable probe for imaging of the P-glycoprotein transport ability to determine drug resistance. The aim of this study was to provide labeled taxol and to determine the rate of uptake in the tumor to evaluate the location of the tumor and the ...
متن کاملPitfalls in the Standard Radiochemical Purity Testing for Technetium·99m·Exametazime
Objective: The purpose of this study was to examine discrepancies in the standard method for determining the radiochemical purity (RCP) of mTc-exametazime. The package insert for mrc-exametazime indicates that the entire RCP testing procedure requires approximately 15 min to complete, although the solvent-developing time for the three-paper chromatography system is described to be s 1 00 sec. A...
