Analytical Chemistry branch of chemistry that deals with separation, identification, and determination of components present in a sample. Also includes coverage of chemical equilibrium and statistical treatment of data. -ex. clinical analysis: blood and urine tests environmental: water purity Forensic: DNA and fiber tests Industrial: drug and metal purity Qualitative Analysis determining what chemical species are present in a sample Quantitative Analysis determining how much of a che...

ANALYTICAL CHEMISTRY Branch of chemistry that deals with the separation, identification and composition of matter Gravimetric Method Measurement of mass of substance that is chemically related to the analyte Volumetric Method Measures the volume of solution necessary to read completely with the analyte. Spectroscopic Method Measures the electromagnetic radiation produced by the analyte or its interactions with it. Electroanalytic Method Measures the electrical properties of the analy...

i. The global findings of this study include the demonstration that SEEBIC imaging is an attractive alternative to electron tomography (ET) for investigating the morphology of nanoparticles. SEEBIC imaging offers shorter acquisition and processing times compared to ET, while providing superior spatial resolution compared to scanning electron microscopy (SEM). ii. The primary analytical achievement of this study is the validation of SEEBIC imaging as a viable technique for high-resolution visu...
