BACKGROUND
[0002] Background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed disclosure, or that any publication specifically or implicitly referenced is prior art.
[0003] Food, in one form or other, is a primary necessity for sustenance of all living species. Food is required for all the living species to grow, work, repair, and maintain life processes. Today there are many different types and varieties of food products available at the market for different purposes, including maintaining weight, increasing height, for party, and the likes. But, one may also face problems due to practice of food adulteration, which is rampant now-a-days.
[0004] Food adulteration is a major issue of concern for most of the countries. Adulterants are the substances of poor quality that are added to food items for economic and monetary benefits. Addition of the adulterants to some food product generally reduces the value of nutrients present in said food product. Sometimes, such adulterants are added to the food that may contaminate the food product and may even result in very harmful effects on the health of a person.
[0005] For example, adulteration in alcohol/ ethanol, which may happen accidentally or can be done on purpose in order to maximise profits. Adulteration of ethanol can also be done by adding methanol to it, in order to prevent its consumption, so that it could be used majorly for medical purposes, for instance, in spirit, as sanitizer, etc. However, according to various reports and data, consumption of adulterated alcohol results in a number of deaths around the world every year.
[0006] There is, therefore, a need to provide a device that may obviate the above mentioned limitations, and enable detection of purity of a fluid, including alcohol.

DETAILED DESCRIPTION
[0028] In the following description, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the present invention. It will be apparent to one skilled in the art that embodiments of the present invention may be practiced without some of these specific details.
[0029] If the specification states a component or feature “may”, “can”, “could”, or “might” be included or have a characteristic, that particular component or feature is not required to be included or have the characteristic.
[0030] As used herein the description and throughout the claims that follow, the meaning of “a,” “an,” and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.
[0031] The following is a detailed description of embodiments of the disclosure depicted in the accompanying drawings. The embodiments are in such details as to clearly communicate the disclosure. However the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosures as defined by the appended claims.
[0032] Embodiments explained herein relate to the field of spectroscopy. In particular, the present disclosure provides a device for detection of purity of a fluid through radio-frequency (RF) spectroscopy technique.
[0033] The study of interaction between matter and electromagnetic (EM) radiation is known as spectroscopy. Results of said interaction could be observed in terms of a function of wavelength or frequency of the EM radiation. Spectroscopy is equally applicable for all bands of the EM spectrum, including visible light.
[0034] Spectroscopy could also be used for detecting purity of a fluid as well as for finding impure substances added to the fluid, by considering spectra obtained after interaction of the fluid with the EM radiation. Molecules and atoms of a particular matter, say some particular fluid, may transmit some part of the EM radiation and reflect some other part of the EM radiation, and also absorb a particular part of the EM radiation. Therefore, a pre-defined fluid would interact with the EM radiation in a pre-defined manner, and therefore based on the obtained spectra, purity level of the fluid can be determined. Moreover, impurity/ impure substances added to the fluid can also be detected.
