Embodiment quality healthy environment are a key part of health. Air as an important component in the life environment needs to be maintained and enhanced blue roll in order to provide power support for living organisms to live optimally. Air pollution is of increasing reveals very poor condition. Sources of air pollution can come from a variety of activities such as industry, transport, offices, and housing. These activities is the greatest contribution of air pollutants discharged into the atmosphere. Sources of air pollution can also be caused by a variety of outdoor activities, such as forest fires, volcanic eruptions, toxic gas, etc..
The impact of air pollution that is causing a decrease in air quality, which have a negative impact on human health. Air is a media environment that is a basic human necessity that needs to get serious attention, it is also the policy of the Indonesian Health Development 2010 in which air pollution control program is one of the ten excellent programs.
Growth industries such as construction, transportation, etc. in addition to providing a positive impact but on the other hand will have a negative impact which one form of air pollution and noise that occurs both in the room (indoor) and outdoor (outdoor) which can endanger human health and the occurrence of disease. blue roll It is estimated that air and noise pollution due to industrial activities and motor vehicles will increase 2 times in 2000 from the state in 1990 and 10 times in 2020.

1. Devices Gas Chromatography (GC) or GC / mass spectrometer (GC / MS) that separates the air compounds so that each can be identified blue roll and measured as the concentration of compounds that pass through the detector.
2. Infrared (IR) instrument where the wavelength of the IR radiation emitted wavelength adjusted to match certain chemical compounds absorb IR radiation. Because many chemicals that have characteristic absorption wavelength, this method blue roll can provide an accurate method of identification. In addition, because the amount of IR radiation absorbed is proportional to the concentration of chemicals, these instruments blue roll provide data concentration.
In particular, many available IR devices are set to emit only one wavelength IR radiation and then specifically for the airborne compounds. As an illustration, a direct reading blue roll instrument for carbon dioxide (CO2) which is based on the principle of IR, and using the absorption of IR radiation at wavelengths of 4.72 pM for the concentration of CO2 in the air.
While GC, GC / MS, IR and instruments blue roll that can determine the concentration of some specific compounds in the air is a mixture blue roll of high-end devices are expensive and sophisticated and complicated its use when operated.
1. All you want to use either a personal computer or laptop to operate the instrument or to manage the data. Identification of compounds and measurement steps by comparing air samples for calibration.
While many options are available, praktikan take samples according to their needs (compounds blue roll to be sampled, the possibility of interference, operating conditions, etc.), which first determines whether they are suitable for technological applications. If so, then the manufacturer's technical staff select and configure the instrument to meet the specific needs of the user.
1. Although this instrument blue roll is an instrument directly, but this instrument is not designed to identify For all these devices, more frequent calibration using a mixture of unknown gas.komponen in air mixture. Instrument achieve accuracy in identifying and measuring the concentration of a single chemical compound
