sample filtration Applications

The scientific community and in particular for that of the life science industries such as the medical, pharmaceutical  and healthcare, have a growing need for superior technologies and products in filtration, separation, purification, aeration and liquid transfer. The range of BioVyon materials and applications are continuously expanding, driven by new market requirements and available to both OEM and end user customers. Applications include separation or filtration for healthcare, medical and pharmaceutical products, shut off valves for catheters, diagnostic wick and sample preparation devices.

Three Steps of CEMS: 1st Step: Gas Sampling 2nd Step: Gas conditioning and treatment 3rd Step: Measurement/Calibration In first step, the function is to get sample gas and forward to 2nd step for treatment. During this step, it cannot block the probes and cannot result condensation of moisture. So a filter online back flushing should be equipped in this part. The filters to be used: 1, Filter is used to ensure the stability of system and reduce the maintenance 2, Filtration Grade: usually 2 or 3 micron 3, Temp. is around 0-180 deg C 4, Back flushing gas is heated, impulse flushing 5, Filter Material: Titanium Sintered, SS316L Sintered, PTFE sintered, Ceramic Membrane and so on 2nd Step Gas Treatment: #11;The coarse filters and the liquid particle filters The coarse and fine cartridge can filter the small particles in the gas and acid aerosol things to better protect the instruments. The micron can be 0.1micron, filtration rate can be up to 99.99%, two layers can be 99.9999%

A wide range of sample acquisition and filtration systems are available to prepare even the most difficult of samples for reliable on-line analyser measurement. The correct choice is often critical to prevent analyser blockage and optimise performance. Cross Flow Filtration The PPM cross flow filter, is a simple in-line device used to protect an analyser from ingress of solids, for applications where sample quality is generally good but occasionally suspended solids may be present. The stainless steel filter removes solids above 50 micron size.
