The TNUSRB SI Exam (Tamil Nadu Uniformed Services Recruitment Board Sub-Inspector Exam) does not typically include a specific section on Analytical Chemistry and Instrumental Methods. However, if you are preparing for a specialized role or a forensic-related position, you might encounter questions related to basic chemistry and forensic science techniques. Below is a general syllabus for Analytical Chemistry and Instrumental Methods that could be relevant for such roles:
—
Syllabus: Analytical Chemistry and Instrumental Methods
1. Basics of Analytical Chemistry:
– Definition and scope of analytical chemistry.
– Qualitative vs. quantitative analysis.
– Types of analytical methods: classical (wet chemical) and instrumental methods.
2. Classical Analytical Methods:
– Volumetric Analysis (Titrimetry):
– Acid-base titrations.
– Redox titrations.
– Precipitation titrations.
– Complexometric titrations.
– Gravimetric Analysis:
– Principles and steps involved.
– Applications in chemical analysis.
3. Instrumental Methods of Analysis:
– Spectroscopic Techniques:
– UV-Visible spectroscopy.
– Infrared (IR) spectroscopy.
– Atomic Absorption Spectroscopy (AAS).
– Flame Photometry.
– Chromatographic Techniques:
– Thin Layer Chromatography (TLC).
– Gas Chromatography (GC).
– High-Performance Liquid Chromatography (HPLC).
– Electrochemical Methods:
– Potentiometry.
– Conductometry.
– Voltammetry.
– Thermal Methods:
– Thermogravimetric Analysis (TGA).
– Differential Scanning Calorimetry (DSC).
4. Applications of Analytical Chemistry:
– Environmental analysis (e.g., water and air quality testing).
– Forensic analysis (e.g., drug testing, toxicology).
– Pharmaceutical analysis (e.g., drug formulation testing).
– Food analysis (e.g., adulteration testing).
5. Sample Preparation and Handling:
– Sampling techniques.
– Sample purification and extraction methods.
– Calibration and standardization of instruments.
6. Data Analysis and Interpretation:

Preparation Strategy:
1. Understand the Basics:
– Start with fundamental concepts of analytical chemistry from textbooks like:
– *Principles of Instrumental Analysis* by Skoog, Holler, and Crouch.
– *Vogel’s Textbook of Quantitative Chemical Analysis*.
2. Focus on Instrumentation:
– Learn the principles, working, and applications of common analytical instruments.
– Use diagrams and flowcharts to understand instrument setups.
3. Practice Numerical Problems:
– Solve problems related to titrations, calibration curves, and data interpretation.
4. Refer to Forensic Science Resources:
– If preparing for a forensic role, study forensic chemistry techniques and their applications.
5. Use Online Resources:
– Watch video lectures on platforms like YouTube (e.g., NPTEL, Khan Academy) for better understanding of complex topics.
6. Solve Previous Papers:
– Practice questions from related exams to understand the pattern and difficulty level.
