the interaction of brilliant green with herring sperm dna was investigated in detail by spectrometric methods in γ-cyclodextrin systems. on the condition of physiological ph, brilliant green prefers to form the 1:1 inclusion complex with γ-cyclodextrin.all the evidences indicated that the binding modes between γ-cyclodextrin-brilliant green and dna were grooving binding and partial non-classica...

Recently, mass spectrometric related techniques have been widely applied for the identification and quantification of neurochemicals and their metabolites in biofluids. This article presents an overview of mass spectrometric techniques applied in the detection of neurological substances and their metabolites from biological samples. In addition, the advances of chromatographic methods (LC, GC a...

Micro-manipulated uranium micrometer-sized particles under optical microscope, measured at picogram level by two mass spectrometric techniques.

Spectroscopic methods have been for years widely used in analytical laboratories. However, their application in industrial and environmental practice has been up to now relatively limited because of the high costs of spectrometric instrumentation. This is only recently that the advances of microand optoelectronics have made feasible integrated implementation of some spectrometric techniques and...

The Baire metric induces an ultrametric on a dataset and is of linear computational complexity, contrasted with the standard quadratic time agglomerative hierarchical clustering algorithm. We apply the Baire distance to spectrometric and photometric redshifts from the Sloan Digital Sky Survey using, in this work, about half a million astronomical objects. We want to know how well the (more cost...

A novel atomic absorption spectrometric method and two highly sensitive spectrophotometric methods were developed for the determination of paracetamol. These techniques based on the oxidation of paracetamol by iron (III) (method I); oxidation of p-aminophenol after the hydrolysis of paracetamol (method II). Iron (II) then reacts with potassium ferricyanide to form Prussian blue color with a max...

spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. this review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques. the use of an appropriate sample handling technique is a...
