A Fluorometric Method for Determining the Riboflavin Content of Foodstuffs
A number of chemical methods have been described for the determination of riboflavin (1-13). These methods are in general limited in use because, when applied to certain products, either they are not specific for riboflavin or all the riboflavin present is not recovered (2). In most cases the authors of papers presenting riboflavin methods have indicated that the methods are of limited applicat...

متن کاملModified fluorometric method for determining plasma catecholamines.
Plasma catecholamines were fluorometrically determined by a modification of the standard alumina-trihydroxyindole method in which radioactive tracer catecholamines are used to follow the chromatographic behavior of the endogenous catecholamines on alumina. This modification permits appropriate fluorometry of that portion of the eluate with the highest concentration of catecholamines, because in...
متن کاملManual fluorometric paper disc method for determining tyrosine in blood.
A spectrophotofluorometric method is described for the determination of tyrosine in blood dried on filter paper discs. It has been found that by immersing the paper disc containing the dried blood in aqueoustrichioracetic acid, the blood proteins remain bound to the paper and the amino acid is eluted into the aqueousphase.This method of assay is based on the principle that tyrosine reacts with ...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
