Analytical Chemistry

Research and findings in the area of analytical chemistry are hugely influential in other fields of science and in society, since it has 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 understand the fundamentals of chemistry, which is studying matter, since analytical chemistry is a field within this field of study.

Analytical chemistry is the scientific as well as quantitative analysis of material, i.e. the type of matter present and the amount. This definition of analytical chemistry is the reason why many believe the analytical field isn't a sub-discipline of the chemistry field. It's actually the same, says David Harvey, Professor of Chemistry in DePauw University.

 

Harvey clarifies that analytical chemistry doesn't mean the same because analytical chemists don't conduct routine analyses on routine samples. An analytical chemist is the one who is "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 describes what the matter is and the amount (the mass) of said matter exists.

Analytical Chemistry's Impact

The discipline of analytical chemistry has been highly influential to our perception of the world around us and for the progress of other scientists' studies. These studies provide the world with knowledge and tools for deeper understanding of physical objects, which can, in turn, have been a huge influence on the world of.

 

For example, a popular breakthrough was a way for doctors to detect or recognize the signs of a potential diagnosis of diabetes using the measurement of glucose.

What is an Example of Analytical Chemistry?

Analytical chemistry can be illustrated using an example taken from a report by the U.S. Department of Commerce regarding an overseas U.S. Air Force base which uses powdered milk in meals.

 

Powdered milk has to be rehydrated, so this base used the local water, and was contacted by complaints of milk that tasted foul which led to the conclusion that something was in the water that is causing it to be a problem. An analytical chemist can analyze the water by identifying and isolating the pollutants in the water and, thus, finding the source of pollution.

 

The job of an analytical chemist is to create a solution to isolate the chemical compounds that are present in water. For instance High-performance liquid chromatography is a method to determine pollutants in liquids. In the end, the chemical chemist's findings revealed that upstream chemical plants contributed to the pollution of the water.

What is the job of Analytical Chemists?

In the modern era of analytical chemistry, analytical chemists resolve problems by measuring the chemical composition of chemical compounds using quantitative and qualitative analysis. Their objective is to address these four questions regarding an element: Which one is it? Where is itlocated? What amount is there? What is its composition and structure?

Process of Analysis

The standard process for analytical sciences follows a five-step approach. Those steps are finding, designing, testing, analyzing, and sharing the results.

1. Identify

The identification phase is the procedure that an analyst chemist goes through in in determining the issue they're trying to solve. It also entails determining the type of tests to use, i.e., qualitative, quantitative, structure, or fundamental.

 

At this stage chemical analysts will determine the necessary accuracy of their research, their budget, and the period of time.

2. Design

The design of the experiment is the process of selecting a method, strategy, and test. One important factor a chemical analyst needs to be aware of is what tools and techniques are already in use for the challenge they're trying to resolve.

3. Experiment

After defining the problem and designing the experiment, the chemical analyst performs their experiments with the appropriate equipment and instruments in their lab.

 

Experiments requiring separation of chemicals could require distillation, precipitation extraction of solvents, solid-phase extraction as well as high-performance liquid chromatography or electrochemical analysis. In this stage, the purpose is to collect information during the process.

4. Analyze Data

Then, the chemical analyst reviews the information by using statistical analysis to assess the validity, accuracy verification and limitations, and interpreting their findings to the client. The analyst repeats the first, third, and fourth steps to verify that the solution is.

Types of Chemical Analyst Employers

Several companies employ analytic chemists; among the most well-known fields include:

 

• Pharmaceutical companies

• Government agencies

• Industrial industry

• Testing labs

• The biological industry

• Environmental sector

• Companies that manufacture drugs

• Energy and Petrochemical companies

• Non-profit organization

Typical Hours of Work

Chemical analysts are always working in a laboratory, working a standard 40 hours a week or longer. The main responsibility of analytical chemists is to meet deadlines, which may require working over 40 hours a week.

Chemical Analyst Average Salary

Based on GlassDoor the analytical chemist earns an average annually of $52k while wages for senior-level positions and leadership positions range between an average of $86,143 and $89,451.

How Many Years Does it Take to Study Analytical Chemistry?

Aspiring analytical chemists should attain the degree of a bachelor's in biochemistry, engineering, or chemical science. In addition, they should do research with assistance and finish an internship in chemical research.

 

Chemists who graduate from a four-year college are well on their path to becoming a chemist. However, those who wish to study or want an increase in their average earnings are advised to continue their education for a master's degree.

Qualifications

• High School diploma

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

• Internships for laboratory technicians and/or research in a laboratory environment

• Graduates and Ph.D. to instruct or work for analytical chemistry companies like labs for analytical chemistry in South Africa

• Join a scientific group to stay up to date in the scientific community , such as ACS Chemists (American Chemical Society).

Skills & Knowledge

• Advanced general and organic chemistry knowledge

• Mathematics (Calculus)

• Computer skills and engineering

• Mass spectroscopy

• High-performance liquid chromatography

• Advanced communication capabilities

• Logic, reason and solving problems

• Analytical techniques

• Data analysis

• Analysis of Gravimetrics

 

The length of time to study for the position of an analytical chemist lasts 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 discipline in the field of chemistry. It involves defining matter by clarifying the nature of it and how much available. It is a complicated job for chemists who work to improve the field of science and to better understand the properties of our physical universe.
