Overview

Mass detector is known as the most efficient detector for qualitative analysis. However, at the same time, it has poor qualitative capacity. Because it only analyzes a small amount of gas, it is difficult to obtain the good quantitative result. By selecting the most appropriate materials and component layout. BEL has successfully produced "BELMass" with a high quantitative capacity. Even ammonia gas can be analyzed easily by using the heat hose and dry diaphragm pump.
