Flame Atomic Absorption Spectrometry
When a sample is introduced into a flame, only a small fraction of the atoms are in an excited or high energy state [as per the Boltzmann equation] and most atoms of the element remain in the unexcited or ground … Read More
The Principle of Measurement of pH
A pH meter is an instrument that determines the acidity or basicity of aqueous solutions.
The measurement of pH is achieved by utilizing a glass electrode that generates an electric potential when solutions of differing pH are placed on the … Read More
How Estimation of Oxygen and Carbon dioxide is Carried out in Biological Solutions
Estimating Oxygen in Biological Solutions
Oxygen concentration in solution is usually estimated electrolytically. The basic principle is that, if a bright platinum electrode is placed in a solution, and +0.7 V is applied to it with respect to a reversible … Read More

We shall look at some of these methods used to estimate the ionic composition of tissue fluids based … Read More
How Flame Photometers are used in Chemical Analysis
Flame Photometer is used to quantify the concentration of Sodium and Potassium in the body.
Basic Principle of Operation of a Flame Photometer
When a sample is heated, the electrons are raised from the ground state to a higher state. … Read More
The Role of Biomedical Analysis in Medical Diagnosis
Chemical changes may occur in the internal environment of the human body due to pathological processes. These chemical changes can be detected by the analysis of various samples taken from the body. This analysis helps in the diagnosis of various … Read More
