Analytical chemistry is the cornerstone of other fields in chemistry. This, branch of science, involves the process of isolating a specific compound, identifying it, and determining how much of the compounds are in a product. The subject checks on the mixtures and compounds, taking note of the proportions measured of the constituents. It consists of two broad methods, that is classical and modern methods.

Methods Used In Analytical Chemistry

Classical methods

Classical methods, well known as the wet chemical methods, is the epitome of analytical chemistry. Traditional techniques characterize it. Most of these techniques are significant and more often adopted by modern methods. The wet chemical methods fall under two analyses, qualitative and quantitative.

The qualitative analysis identifies whether a particular compound is present or absent in a substance. This analysis falls under two tests which specify the type of compound being analyzed — the chemical test checks on the availability of chemical compounds like the presumptive Kastle-Meyer test on the presence of blood. The flame test detects the presence of material such as metal ions. Flame test notes the different colors of different compounds with relation to temperature change.

Quantitative analysis monitors the proportion of chemical constituents available in a substance. Quantitative analysis is categorized into two studies. Volumetric analysis, also known as titration, involves the addition of a reactor to a solution being analyzed to find the proportions of the chemical constituents. The gravimetric analysis determines the number of constituents present by weighing the sample before and after an alteration.

Modern methods of Analytical Chemistry

It is a branch of analytical chemistry that investigates compounds using scientific instruments. It is also known as the instrumental method. The instrumental techniques of analytical chemistry are divided into categories, according to the property of the material that is measured. These methods are often based upon wet chemistry methods. However, in this case, they have been modified to precision and are faster compared to classical methods.

Significance of Analytical Chemistry

Analytical chemistry is a crucial player in this day and age. Almost all sectors recognize its relevance to society. Below are some of the impacts the subject matter has contributed to society. In the pharmaceutical sector, it is used to check the quality of drugs, the organic and inorganic compounds, and other useful chemicals. It helps in determining the shelf-life of a mixture to guarantee the drugs' safety and when its expiry date is likely to elapse. Another critical point to note is it ensures the formulation is within limits of contamination. High contamination of the batch is easily detected and hence destroyed.

The health sector cannot be left behind. It hugely relies on analytical chemistry in diagnostic tests. Like in serum cholesterol, the use of spectrophotometry aids in quantifying the superficial colored layer containing cholesterol. Usage of titration also helps in determining the availability of glucose in the blood.

In a nutshell, analytical chemistry is a robust precedent in our educational system and the world at large. Scientists strive to advance the methods and continuously modify the instrumental techniques for more accuracy, and ensure the final products are fit for consumption for the masses. Therefore, the study is crucial for all sectors in society, and its usefulness is highly commended in this day and age and the future to come.
