Article
Colorimetric sensors have a number of advantages, including easy fabrication, rapid quantification, great sensitivity and selectivity, and naked-eye detection. Using Fe3O4 nanoparticles, we present a simple and effective nano-sensor array for colorimetric detection of arginine and ascorbic acid. When utilized in biodetection, however, changes in th...

Spectroscopy methods, as the basic analytical instrumentation methods, are employed in different sciences. They have a wide range of applications in chemistry. Small spectrometers are divided into laboratory portable instruments, field analyzers, and process analyzers. Miniaturized spectroscopic instruments are one class of portable spectrometers....
Chapter
Separation instruments including gas chromatography, high pressure/performance liquid chromatography, capillary electrophoresis, and ion chromatography have become a part of most of the analytical laboratories. These methods are primarily used for the separation of complex samples and quantitation of a target analyte in the sample. Some of these in...
Article
Metal oxide semiconductor sensor have a drawback of similar gas sensing response to homogeneous gases. Taking H2 and CO with similar properties (reducing gases), these sensors cannot detect the concentrations of both gases, because the MOS sensors have cross-sensitive behavior to H2 and CO. In this paper, SnO2-Mn3O4 nanocomposites are prepared by s...
