Laboratories: Analytical

Analytical laboratories are where investigation of the components of matter is conducted. The person who works on this type of laboratory is called an analytical chemist. The role of analytical chemists is important as they greatly contribute to the field of chemistry. Their job includes performing laboratory research, designing instruments for lab use, develop procedures and can even engage in teaching. When conducting experiments, they follow a thorough process before finally coming up with a result. The first thing that they would do is to study the samples, calibrate test results, interpret the gathered data and then report the result. The services of analytical chemists are usually sought out by private industries, government and academic organizations.

 

To be an analytical chemist, one has to have at least a bachelor’s degree and preferably taken advanced studies, a master’s degree, in order for him to compete with other chemists. They are expected to have in depth knowledge of chemistry with good knowledge in statistics, instruments and computers to produce results. Since they are employed to help solve problem for various industries, it is important to have a background in business and management course. They should also be able to perform quantitative and qualitative analysis in revealing the internal structure and components of inorganic and organic matter. Their aim is to thoroughly understand the nature of matter, how it can be measured and its behavior when put in different conditions.

 

The analytical laboratories that these chemists work in vary. Their differences are based on the requirements of the task assigned by the industry they are engaged as chemicals and pharmaceutical companies deal with different products. There are various analytical methods that chemists employ and they can be categorized to either wet bench chemistry or instrumental analysis. Wet bench chemistry mostly deals with qualitative analysis such as melting points, boiling points, texture, color and other observable factors. It can also perform basic quantitative analysis including weight, volume and potenz hydrogen (ph) measurement. Recrystallization, titrations, flame tests, basic chromatography and precipitations are also some complex analysis can also fall under wet bench chemistry.

 

Instrumental analysis is conducted to matters that require more investigative observation. The typical methods that belong on this group are chromatography, spectrometry, electro-analytical methods and spectroscopy. Instrumental analysis involves more sophisticated instruments and may be housed in a state of the art facility. Even though one analytical laboratory holds better features than the others, it does not mean that the investigation being conducted in simpler laboratories are less significant. Analytical chemists that do not conduct analysis can find work in instrumentation vendor labs as sales and marketing chemists.

 

Accuracy on their report is crucial for analytical chemists to keep their reputation and the analytical laboratory they are in. In order to avoid errors and mistakes in their procedure, chemistry quality control program is usually implemented. If not carelessness, the other common cause of error may be boredom brought by doing monotonous tasks. Since precision on the report is important as the analysis especially if dealing with food and pharmaceutical industries, quality control program implement rotation of tasks between employees, applying several tests and comparing reports.
