Analytical Chemistry

The research and findings in the area of analytical chemistry are massively influential in other scientific areas and the society as it's resulted in environmental corrections as well as diagnosing health issues.

What is Analytical Chemistry? - Definition & Impact

To first understand analytical chemistry, it's important to comprehend the fundamentals of chemistry that is, studying matter since analytical chemistry is a field within this area of study.

Analytical chemistry is the scientific as well as quantitative analysis of material, i.e. what's present and the amount. The definition of analytical chemistry is one of the reasons why some argue the analytical field isn't a sub-discipline of the chemistry field. In fact, it's the exact same, says David Harvey, a professor of chemistry at DePauw University.

 

Harvey clarifies, however, that analytical chemistry isn't the same because analytical chemists don't perform routine analysis on routine samples. An analytical chemist is that process of "improving established methods, extending existing methods to new types of samples, and developing new methods for measuring chemical phenomena."

 

So, in the simplest sense, analytical chemistry defines what the matter is and the amount (the weight) of that matter is present.

Analytical Chemistry's Impact

The discipline of analytical chemistry has been influential in our understanding of the physical world as well as for the advancement of other research studies. The research provides the world with knowledge and tools for deeper understanding of physical objects. This is why it has been a huge influence on society.

 

For instance, a fas-sudden breakthrough provided doctors to detect or recognize the signs of a potential diagnosis of diabetes by the measure of glucose.

What is an Example of Analytical Chemistry?

Analytical chemistry can be illustrated with an example from a paper published from the U.S. Department of Commerce regarding an overseas U.S. Air Force base using powdered milk for meals.

 

Powdered milk needs to be rehydrated, so this base used the local water. It also received complaints of milk that tasted foul which led to the conclusion that something was polluting the water. Analytical chemists can analyse the water by isolating and identifying the pollutants in the water and this is the way to determine the source of the pollution.

 

Analytical chemists' job is to devise an approach to identify the chemical compounds that are present in water. For example the high-performance liquid chromatography technique can identify the presence of pollutants in liquids. The scientist's findings proved that chemical plants upstream contributed to the pollution of the water.

What do Analytical Chemists do?

Modern analytical chemistry analytical chemists solve issues by analyzing the chemical composition of chemical compounds through qualitative and quantitative analysis. Their objective is to address these four questions regarding an element: How does it work? Where is it? What is its size? And what is its composition and structure?

Process of Analysis

The standard process for analytical sciences follows a five-step approach. These steps include identifying, designing, experimenting with, analyzing and sharing the results.

1. Identify

The identification phase is the process that an analyst chemist goes through in identifying the problem they're attempting to solve. It is also about choosing the kind of test to utilize, i.e., qualitative, quantitative, structure, or fundamental.

 

In this phase chemical analysts will determine the necessary accuracy of their results, the budget, as well as the time frame.

2. Design

The plan of the experiment is the process of choosing the right strategy, method, and sample. A crucial aspect an analyst in chemical science must know is what tools and techniques are available to solve the issue they're trying to resolve.

3. Experiment

After defining the problem and conceiving the experiment the chemical analyst experiments using the right equipment and instruments in their lab.

 

Experiments that require chemical separation may require distillation, precipitation extraction of solvents, solid-phase extraction, high-performance liquid chromatography, and electrochemical analysis. At this stage the goal is to gather data during the process.

4. Analyze Data

Then, the chemical analyst analyzes the data using statistical analysis to determine its validity, accuracy verification and limitations, as well as interpreting their findings for the client. The analyst repeats the first, third, and fourth steps to verify that the solution is.

Types of Chemical Analyst Employers

A variety of industries employ analytical chemists. some of the most popular fields are:

 

• Pharmaceutical companies

• Government agencies

• Industrial industry

• Testing laboratories

• Biological industry

• The sector of environmental protection

• Drug manufacturing companies

• Oil and gas companies

• Non-profit organization

Typical Hours of Work

Chemical analysts are constantly working in laboratories in a lab environment, and work 40 hours per week or more. An analytical chemist's main task is to meet deadlines, which may require working over 40 hours a week.

Chemical Analyst Average Salary

According to GlassDoor GlassDoor, an analytical chemist earns an per year salary of $58K, and salaries for higher-level positions and leadership positions vary between an average of $86,143 and $89,451.

How Many Years Does it Take to Study Analytical Chemistry?

Analytical chemists who are interested in becoming an analyst should earn a bachelor's degree in engineering, biochemistry, or chemistry. They should also be involved in research assisted by a mentor and complete a chemical internship.

 

Chemists who graduate from a four-year college are on their path to becoming a chemist. But, those who wish to research or desire a higher average salary should consider continuing higher studies for a master's.

Qualifications

• High School diploma

• Bachelor's degree that focuses on courses in chemistry, maths or physics.

• Laboratory technician or research internship in a laboratory environment

• Masters or Ph.D. to instruct or work for companies that deal in analytical chemistry like labs for analytical chemistry in South Africa

• Join a scientific association to stay up to date in the world of science, like ACS Chemists (American Chemical Society).

Skills & Knowledge

• Advanced organic and general chemical knowledge

• Mathematics (Calculus)

• Computer skills and engineering

• Mass spectroscopy

• High-performance liquid chromatography

• Advanced communication abilities

• Logic, reason, and solving problems

• Analytical techniques

• Analysis of data

• Gravimetric analysis

 

The time required in order to be an analytic chemist is approximately four to five years, and two to six additional years to earn a master's degree or Ph.D.

Final Thoughts: What is Analytical Chemistry in Simple Terms?

Analytical Chemistry is a field within the field of chemistry. It's the process of defining matter by delineating what it is and the quantity in existence. The practice is a complex job for chemists who work to improve the field of science and to better understand the properties of our physical universe.
