JURNAL POLARIMETER PDF

Article Info Publish Date 13 Jan The aim was to confirm the impact of attachment of -carbon atom of the systems to the four different groups, that is, the -carbon or methyl group, H-group, CO2H-group and NH2-group, to their response to any incoming plane-polarized light. Optical activity of a substance is a measure of the ability of a substance to rotate a plane of polarization, if solution of the substance is placed in the path of plane-polarized light. A polarimeter of Perkin-Elmer Model with a Sodium lamp of nm wavelength D-line and equipped with a digital counter was occupied in this work to measure the number of degrees of rotation of plane-polarized light at room temperature due to 8. While the molecules of D-isomer rotate the counter anti clockwise, at the similar amount of rotation.

While the molecules of D-isomer rotate the counter anti clockwise, at the similar amount of rotation. These results confirm the asymmetric structure belong to the -alanine system. Molecules of DL-isomer, however, do not rotate the counter at all.

The existence of similar number of the D- and L-molecules in the DL-solution is the cause. Citation Download. Full PDF. Original Source. Download Original. Google Scholar. Institut Teknologi Sepuluh November. Naskah yang dikirimkan ke JFA belum pernah diterbitkan

JURNAL POLARIMETER PDF

Polarimeters are useful instruments that measure concentrations of optically active substances in a given solution. The conventional polarimetric principle consists of measuring the rotation angle of linearly polarized light. Here, we present a novel polarimeter based on the study of interference patterns. A Mach—Zehnder interferometer with linearly polarized light at the input is used.

Column chromatography was performed using a silica-gel. Kieselgel 60, mesh and mesh,. Reviewing the following tips should improve the accuracy and utility of sugar data in determining fruit Chinese Professional JF-1 series glass surface He subtracted the percentage of sucrose from Poarimeter of Physics E: American journal of veterinary research, 68 9: Volume 9, Issue 7 Ver. Comparative analysis of monosaccharide and disaccharides were carried out with the aid of refractometer and polarimeter This new method was carried out by using ultrasonic waves whose velocity depends on the sucrose content. To overcome this problem we have developed an oolarimeter method that can measure the sucrose content more quickly and accurately than the conventional methods.
