The aerosol cycle of e-cigarette a technical introspection Aerosol
Aerosol : What it actually is
Primarily the components that build up an e-cigarette are: a mouthpiece, a cartridge, a heating element or atomizer, a microprocessor chip, a battery and also sometimes a LED light to indicate the puffing action by the user. When the user inhales or pushes the button, a pressure sensor activates the heating element that atomizes the liquid solution. The e-liquid heats up to a temperature of around 100-250° Celsius within a small closed chamber to fumigate the aerosolized vapor. The user inhales the aerosol / vapor, instead of the smoke of the tobacco burning though the feel is quite similar to it.
First Part of its cycle
Aerosol is the form of liquid which is produced by the e-cigarettes. It is a phase of some e-liquid (or technically it may be of something solid too) in gaseous form where very small, tiny particles of the liquid remains suspended. These tiny particles can themselves be in either in liquid or in microscopic solid forms. Since the e-liquid contents are mostly made of propylene glycol, glycerol, water, flavorings, nicotine and other chemicals, the vapor or aerosol holds the particles of the same items. As the user puffs the button of the device, the particles in some visible form of condensed vapor is inhaled, thereby travel to the respiratory system and lungs through the user’s mouth.
The nicest thing is that, though the particles drive down the systemic circulation of your body, the size of these nano-particles are so very small that they do not get deposited in the walls or alveoli of the lungs. After the gaseous exchange takes place there, the particles get clubbed to one another to form some larger particles and get outside through the exhaled air.
The Second part
After the inhale, there has to be an exhale, right after the so-called experiencing of smoking i.e. technically after the partial absorption of the particles there has to be a release! The greatest news of using e-cigarettes is it doesn’t pollute the environment. The concentration of the exhaled aerosol particle is some 5 times lower than an e-cigarette than from a traditional cigarette. The particle density in the vapor is also much lower than in regular cigarette smoke.
The liquid particles usually get condensed into fog. The vapor remains in the air for a awhile, quite unlike the exhaled traditional cigarette smoke that remains in air 100 times longer for fast re-vaporization at room temperature.
The Third and final part
Researchers say that the non-smokers or so called passive smokers are safer here in case keeping up the e-cigarette user’s company. The children are finally safe from their parents’ inhaling habit!
