3 0 0 3
The course is designed to equip the students with an adequate knowledge of a number of analytical tools which are useful for clinical analysis in hospitals, drugs and pharmaceutical laboratories and above all for environmental Pollution Monitoring.
i. To provide various techniques and methods of analysis which occur in the various regions of the spectrum. These are the powerful tools used in Clinical and Research laboratories.
ii. To give unique methods of separation of closely similar materials, the most powerful being gas chromatography.
iii. To study important methods of analysis of industrial gases. Awareness and control of pollution in the environment is of vital importance.
iv. To bring out the latest ideas on ion-selective electrodes as well as biosensors which have potential applications in medical field, food and beverage industries.
v. To provide the important electromagnetic resonance and microscopic methods of analysis.
Further they are both sensitive and specific and often are characterized by good accuracy. NMR & ESR and microscopic techniques are useful in structure determination.
