Product Introduction:
Unique patented technology, integrated dynamic and static structural design, software controlled switching, can be used for static dilution of laboratory steel tanks to save standard gas. The static part can achieve a dilution ratio of up to 10000 times in a single dilution, without the need for secondary dilution, which is faster and more convenient. It can also be used for online dynamic dilution, with multi-purpose functions, wide application range, flexible and convenient use, and efficient utilization of laboratory space.
Product advantages:
Innovative static and dynamic integrated dilution design, independent standard gas and sample gas channels, multifunctional and non cross contamination; All gas pipeline components are made of 316 stainless steel and undergo strict silane inert treatment; It has necessary functions such as leak detection and pressure detection, dilution of standard gas, dilution/stamping of sample gas, and dilution of standard gas with headspace gas; Software preset methods and one click execution of common functions are extremely easy for users who lack experience in using them; Innovatively adopting high standard MFC compensation dual control units, the highest first-order dilution can reach 10000 times.
Application scenarios:
1. Fixed pollution source online or sampling analysis (point source monitoring)
2. Online monitoring of unorganized emissions at the factory boundary (factory boundary station)
3. Online atmospheric monitoring (air station/atmospheric station/regional control station/national station)
4. Environmental air sampling and detection (point sampling/encrypted sampling/daily average sampling)
5. GC-MS laboratory testing of atmospheric pre concentration pretreatment for Su Ma tank sampling
