Qualitative Analysis| 4 Methods & Uses In Chemistry

Qualitative Analysis

Qualitative analysis by definition is the process of estimation or determination of the components present in a given sample. Chemical analysis has two parts as a) qualitative aspect b) quantitative aspect. Qualitative aspect is the primary property determined and quantitative is the next one in most determinations. Qualitative analysis is quality control for many products […]

Antibiotic sensitivity test procedure

Antibiotic sensitivity test

Antibiotics are natural or semi-synthetic agents which kill bacteria and other microbes at small doses. The number of antibiotics used in present health care system are many yet not all of them are suitable for every kind of infection. For example rifampicin is best for treatment of tuberculous infection while penicillin is best for syphilis. But these two antibiotics are completely ineffective in vice verse manner. This knowledge of selectivity of an antibiotic […]

Particle Definition & Importance of Particle Size

Particle Definition

A particle is a fine solid material which is formed either due to condensation of fine solid mass or breakage of large solid mass into smaller single entities. Particle Definition: “Particles are the small and discrete fragments of matter which tend to flow and spread.” They have a set of properties which define the nature of the […]

Atomic Absorption Spectroscopy | Instrumentation & applications

atomic absorption spectroscopy

Atomic absorption spectroscopy (AAS) is another interesting type of spectroscopy. It is specifically designed for the analysis of the metals and metalloids substances. By definition, AAS is a quantitative analytical technique wherein the absorption of a specific wavelength of radiation by the neutral atoms in the ground state is measured. The more the number of […]
