Chemical analysis with instruments and methods used to separate quantity and identify the Matter. separation, identification or quantification join with other methods also. Separation used by Classical qualitative methods such as Precipitation, extraction, distillation. precipitation means the creation of a solid from a solution, extraction is used to separate the substance, distillation method used to isolate the substance in liquid mixture by boiling and condensation. Identification is in different ways such as colour, odour, melting point, boiling point, radioactivity, or reactivity. Analytical chemistry is important in the early days providing cbr test manchester methods for determining which substance and chemicals are reacting in the object. In academic Focus on a new method to analyze the chemical. Analytical methods are important in the pharmaceutical industry. Many techniques were used to identify the chemical in 1970. Major improvements in analytical chemistry took place in 1900. It is used to identify the drug candidate and clinical applications that react between the drugs and patients are critical.

Classical methods

Classical methods contain many methods to identify the chemical reaction. Some chemical analyses are used in modern instruments from traditional instruments and some techniques are used today. Qualitative analysis is used to find the present and absence of chemicals. It is not used to measure the quantity. Two types of tests in a qualitative method first one is a chemical test and the second one is a flame test. Chemical tests used to find which chemical was present in the elements, for example, the acid test for gold. A flame test is used to analyze certain aqueous ions or elements. This method is rarely used but it is mainly used for educational purposes. Quantitative analysis is used to measure the number of elements. Many types of methods are used, the first one is Gravimetric analysis and the second one is Volumetric analysis. Gravimetric analysis is used to calculate the elements before or after the reaction. Volumetric analysis, titration involved to bring the solution correctly. An acid-base titration is used to color changing and potentiometric titrations involved in indicators to reach an equal point.

Instrumental methods

The instrumental method is one of the methods in chemical analysis. There are many types of methods in instrumental methods Spectroscopy, mass spectrometry, Electrochemical analysis, Thermal analysis, Separation, Hybrid techniques, Microscopy, Lab-on-a-chip. Spectroscopy is used to find the interaction of the molecules. atomic absorption spectroscopy, atomic emission spectroscopy, ultraviolet-visible spectroscopy, x-ray spectroscopy, fluorescence spectroscopy, infrared spectroscopy, Raman spectroscopy, dual-polarization interferometry, nuclear magnetic resonance spectroscopy, photoemission spectroscopy, Mossbauer spectroscopy are consists mainly in spectroscopy. The electrochemical analysis is used to measure the volt and current. There are four types of electrochemical: potentiometry, coulometry, amperometry, and voltammetry. Mass spectrometry used to measure the mass-charge of molecules using magnetic fields and electricity. Thermal analysis is used to measure the materials. Separation is used to reduce the difficulty of material mixtures. Hybrid techniques are a combination of the above techniques and new hybrid techniques are in development. Hyphenated separation techniques refer to two combinations of techniques to detect and separate the chemical. Hyphenated techniques are mostly used in chemistry and biochemistry. Microscopy is used to visualize single molecules, single cells, biological tissues, and nanomaterials. There are three types in microscopy such as optical microscopy, electron microscopy, and scanning probe microscopy. Lab-on-a-chip is used to measure the small amount of fluid less than picoliters.
