  Abstract:  Mass spectrometers are among the most precise and sensitive tools for chemical and isotopic analysis but the laboratory instruments are very expensive and bulky. Our paper is aiming to develop mass analyzers as a mini system with reduced size, rugged and transportable. These analyzers are being designed for applications that include in-situ environmental monitoring and inspection. Therefore, it allows the rapid detection of hazardous chemical compounds in air, soil and water. This paper presents the concept of a few mass analyzers, which were specifically designed for the small dimensions, instruments in such a way that they would be able to detect with sufficient sensitivity and accuracy all type of environmental pollutants.
