Nitrobenzene is known as nitrobenzol or oil of mirbane, is a poisonous organic compound with an almond odor. It is used as a solvent and as a mild oxidizing agent. It is most frequently used specifically in the manufacture of aniline and used in the manufacture of insulating compounds & polishes. Nitrobenzene is also used in shoe & floor polishes, leather dressings, paint solvents and other materials to mask unpleasant odors. Nitrobenzene is used as an inexpensive perfume for soaps.

Nitrogen is a nonmetallic element that constitutes nearly four-fifths of the air by volume, occurring as a colorless, odorless, almost inert diatomic gas. It has the symbol N and atomic number 7. Nitrogen is a constituent element of all living tissues and amino acids. Many industrially important compounds, such as ammonia, nitric acid, and cyanides, contain nitrogen.

Nitrogen dioxide (NO2) monitors are portable desktop instrument, which includes an internal pump. Nitrogen Dioxide concentrations in air can be measured with a resolution of 0.1 ppm and a range 0-20 ppm. The LCD display updates the concentration every 10 seconds. It also computes a 15-minute average and a time-weighted average. The internal pump can be combined with an extendable probe, to make it possible to sample from hard to reach areas or confined spaces.

Nitrogen Gas Flushing Sealing Machine is used in packing of fragile food products like potato wafers, banana wafer and fine noodles. It is used to maintain aroma, freshness, crispness for long time as well as to protect fragile products from breakage/damages. The feature includes easy operating with foot switch, adjustable bag rest, impulse, visual indications during sealing, vacuumising before nitrogen flushing.

Nitrogen Generators provide two way of generating nitrogen. In one approach, compressed air passes across a semi-permeable membrane that allows nitrogen to permeate and almost completely impedes the transfer of other air components and contaminants at high flow rates. The second approach is a two stage process that uses two adsorption beds of carbon molecular sieves. Air enters the front of the cylinder and as it passes through the cylinder, it is separated in to oxygen and nitrogen. The nitrogen is allowed to move out of the first bed until the oxygen nears the end of the carbon bed. At this point the flow is reversed in the cylinder and nitrogen coming off the second cylinder is allowed to purge the first cylinder. This process is called pressure swing adsorption. Alternatively both cylinders are charged with air and provide nitrogen. The nitrogen is used to both purge and reverse flow the cylinder being cleaned and to provide nitrogen for analytical purposes. Additional purification is still required and hence passing the nitrogen leaving the generator through supplemental purifiers can reduce the oxygen, carbon dioxide and water levels in the nitrogen even lower than the sub parts per million levels supplied by the generator.
