We describe a simple method for quantitative chemical analysis of urinary calculi requiring no specialized equipment. Pulverized calculi are dried over silica gel at room temperature and dissolved in nitric acid, which was the only effective agent for complete dissolution. Calcium, magnesium, ammonium, and phosphate are
form of oxides or carbonates or organic derivatives) at higher temperatures, which results in inhomogeneity, bigger crystallite, poor stoichiometry, phase impurity, etc. [22, 271. These problems could be overcome using low temperature wet chemistry methods. Various wet chemical techniques such as, sol-gel, hydrothermal,
Nanocrystalline samples of ZnO doped with Fe2O3 were synthetized by wet chemical method. The series of ZnO nanosized samples in the wide range of Fe2O3 concentration (from 5 wt.% to 95 wt.%) was prepared by precipi- tation from nitrate solutions using ammonia. The phase composition of the samples was
1) Wet Chemical Analysis. 2) Powder or wet spectroscopy. 3) In-situ spectroscopy. 0Once again, depending on your goals, some methods of chemical analysis may be more appropriate than others; however, there is considerable overlap between all techniques. 0In general, wet chemistry involves dissolving a mineral in
Analytical methods can be classified as classical and instrumental. Classical methods are also known as wet chemistry methods and are a term used to refer to chemistry generally done in the liquid phase, which is also called as bench chemistry. However, bench chemistry and wet chemistry terms differ in two primary ways:
Wet chemistry is a form of analytical chemistry that uses classical methods such as observation to analyze materials. It is called wet chemistry since most analyzing is done in the liquid phase. Wet chemistry is also called bench chemistry since many tests are performed at lab benches.

'Wet' Chemical Techniques. • One technique to analyze the chemistry of a mineral is to dissolve it. – Water, Strong acids/bases, hydrofluoric acid, oxidants, fluxes of other Spectroscopy – different methods of studying how different parts of the electromagnetic spectrum (of which visible light is a small part) are affected by
A. Classification of Analytical Methods. A.1. Classical Methods. Classical methods/ wet chemical methods/ earliest methods of analysis; relied mainly on chemical properties of analytes. Analytes are treated with reagents to form products that could be identified. Gravimetric and titrimetric methods were used for quantitative
ABSTRACT. An alternate method to the common tech- nique of evaporating a metallic coating on cells to render them conductive for scanning electron microscopy is de- scribed. This wet chemical technique is less expensive and easier to use, but is not as widely applicable as the evap- orative technique. It should prove
