What Is Chemical Analysis?

Chemical analysis is a testing method conducted to determine the components of a material or compound. This analysis is used to examine the quantity and structure of elements, compounds, ions, or other chemical constituents present in a substance. Chemical analysis helps identify the purity, composition, contaminants, and other characteristics of materials.

What Is the Standard?

The standards used for chemical analysis are generally established by international organizations and industry bodies. Some of the most commonly used standards include:

• ASTM (American Society for Testing and Materials): Defines procedures for analyzing different materials and compounds.
• EPA (Environmental Protection Agency): Provides standard testing methods for environmental and chemical analyses.
• DIN and EN Standards: Contain chemical analysis methods widely accepted across Europe.

These standards help ensure the accuracy, reliability, and repeatability of chemical analyses.

How Is It Performed?

Chemical analyses are carried out using various laboratory techniques and equipment. The following basic steps generally outline how chemical analysis is performed:

1. Sample Collection: The first step is to obtain a correct and representative sample from the material to be analyzed.
2. Preparation: The sample must be in a suitable form for analysis. This may involve dissolving the sample in solvents or preparing it in acidic or basic environments.
3. Selection of Analysis Method: The appropriate analysis method is chosen based on the type of sample and desired results. This may include techniques such as chemical titration, spectroscopy, chromatography, or mass spectrometry.
4. Testing: The selected method is applied to separate the chemical components and measure their quantities.
5. Interpretation of Results: The obtained data are converted into meaningful information about the composition of the material and reported accordingly.

Why Is It Performed?

Chemical analyses are performed to accurately determine the components of a substance and to ensure quality control. They also play an important role in environmental, industrial, and medical applications. The main reasons for conducting chemical analyses include:

• Quality Control: To ensure that products comply with quality standards.
• Health and Safety: To detect harmful components or contaminants.
• Environmental Protection: To monitor pollutants in water, air, and soil samples.
• Medical Diagnosis: To analyze chemical substances present in the human body or biological samples.

What Are the Application Areas?

• Chemical and Pharmaceutical Industry: Chemical analysis is performed to verify the accuracy of the composition of drugs and chemical compounds.
• Food and Beverage Industry: Used to determine the nutritional value, additives, and contaminants present in food products.
• Environmental Sciences: Applied to analyze air, water, and soil samples for pollutants and contaminants.
• Automotive and Metal Industry: Used to test the metallurgical properties and purity of materials.
• Petroleum and Energy Industry: Conducted to analyze the components of crude oil, natural gas, and refined products.
• Medical Laboratories: Used to analyze the chemical components of biological samples such as blood, urine, and other body fluids.

Equipment and Techniques

• Spectroscopy (UV-Vis, IR, NMR, etc.): Determines the chemical structure of substances by examining their interaction with light.
• Chromatography (Gas and Liquid): Used to separate the components within a mixture for identification and quantification.
• Titration: Determines the concentration of a compound using chemical reactions between known and unknown substances.
• Mass Spectrometry (MS): A highly sensitive technique used to study the chemical structure and components of substances.
• Electrochemistry: Analyzes chemical components by using electrodes and electric currents to detect chemical reactions and concentrations.

Advantages

• High Precision: Chemical analyses determine the composition of substances with exceptional accuracy.
• Wide Range of Applications: Chemical analysis is suitable for numerous industries and scientific fields.
• Comprehensive Information: Provides in-depth insights into the chemical structure and content of a material.
• Environmental and Health Safety: Plays a critical role in detecting harmful compounds and ensuring safety compliance.

Disadvantages

• High Cost: The equipment and techniques used in chemical analyses can be expensive.
• Time-Consuming: Complex analyses may take considerable time to complete.
• Requires Technical Expertise: Chemical analyses are complex processes that demand specialized knowledge and experience to obtain accurate results.
• Sample Preparation: Proper sample preparation is crucial for accuracy, and this process can sometimes be complicated.
