Hydro cyclone units are applied in order to separate coarse and fine solid particles from liquids . These type of separators are particularly capable of separating sand, starch, and other finely distributed materials. With hydro cyclones it is possible to separate fine particles online during the process. Hydro cyclone units are used to separate, classify, and to thicken suspensions. Also, these units are used to purify ores and minerals. Also, in fibre technique and paper industry they are applied in purification processes to separate dirt. Hydro cyclones are frequently run in parallel mode. The lay out and design of hydro cyclones are performed empirically similar to the duct cyclones. In the lower flow region of a hydro cyclone an air swirl forms during the separation process, which is not substantially influencing the cyclone flow. Because of the large dimension of the cyclone, wall friction has much more influence on the flow.

The gas cyclone belongs to the mostly applied technical separators, because it has applicationwise some fundamental advantages. One of them is certainly the fact that its construction does not show any movable components. For the large variety of different kinds of dispersed (particulate) phases (for example dust particles, metal chips, wooden waste, liquid droplets) and different gas conditions (pressure, temperature) the lay out and computation of a cyclone is still a complex task. Suvis has specialised in the development and lay out of cyclone separators and can offer professional solutions and consulting in the area of gas cyclones. Many years of experience gained through numerous cyclone development projects results in optimal solutions for our customers. A cyclone separator applies centrifugal forces and represents an effective apparatus for separating gas, liquid or solid particles from a continuous phase in chemical, process or environmental engineering.

The Suvis GmbH also deals with the application of modern numerical methods for the lay out and optimisation of various separator types like cyclones. A typical application of these computation methods is the computer aided investigation of particle separation from gases in cyclones. The prediction of the separation efficiency allows the reliable optimisation of conventional cyclones and the development of completely novel high efficiency cyclones. With that, very often expensive filter units, wet cleaner, or costly electro filters can be replaced or completed. When applying numerical methods (CFD simulations) to cyclones one encounters the problem of strong curvature of the stream lines because of the resulting strong swirl flow and the abrupt change of flow direction towards the outlet tube. This means that the assumption of isotropic turbulence is not useful anymore.

Minimize false readings or premature degradation Gas-absorbing filters from Porex target specific gases that may cause a sensor to have a false reading or cause premature degradation of the cell itself. Specifically designed for your sensor devices, our gas-absorbing filters: Are effective at capturing a wide range of gases that can be harmful to your sensor, including H 2S, SO 2, HMDS, organics, alcohols and many others. Absorb larger amounts of the problem gas –Compared to competitive materials, POREX® filters absorb more problem gas per unit volume, lasting longer than competitive products. Contain safe materials–POREX filters are constructed with safe-to-use reagents, unlike competitive products with toxic lead-containing components.

The FAN ci2 is a highly sensitive analysis instrument for the determination of the ratio of the stable isotope 13C and 12C in the CO 2 of respiratory gases. The field of application for the device are all diagnosis techniques in which tracer substances marked with the 13C stable isotope are catabolized and finally expelled through respiration. The 13C breath test analyzer FAN ci2 can be equipped with a highly stable dual beam infrared spectrometer module. So this device with its 8 or 16 ports is suitable both for medical routine diagnostics and for long term measurements with high demands for precision and stability. The included FANci–software for measuring and interpretation supports all current operating systems of the connected PC. You are free to select from more than 20 integrated breath tests, e.g. Helicobacter pylori test, liver function test, or measuring intestinal transit time. FAN ci2 is the ideal device for physicians’ office laboratories as well as for scientific institutes. Special features simple and save handling small sample volume (approx. 100ml) high performance (approx. 30 samples/h) high repeatability (standard deviation < 0.5‰) low servicing by internal checks of system status wide field of application by flexible adaptation to special questions Fields of application Medicine diagnostic studies for Helicobacter–gastritis investigation of aminoacid metabolism monitoring the circulation of bile acid detection of fat malabsorption indication of bacterial overgrowth in the jejunum specific liver function tests measurement of gastric emptying rate of solids determination of the lactase activity with 13C labeled cornstarch test of the pancreas function with the lipase enzyme Animal nutrition and biochemistry utilisation of feedstuff dynamics of metabolism Operating principle The principle of measurement is based upon the specific absorption of infrared light in the middle of the infrared spectrum between 2 and 8µm wave length (NDIR: Non Dispersive Infrared Spectroscopy). The high selectivity of the infrared detectors is obtained by filling themselves with the corresponding components, 13CO 2 and 12CO 2 respectively. The cross sensitivity of 13CO 2 to the high 12CO 2 concentrations is reduced by using a 12CO 2 gas filter in the 13CO 2 channel and mathematical hods. To yield the high accuracy the temperature is stabilized by thermostat and the system is closed to the environment. Software The control of the FAN ci2 is realized by the FANci WINDOWS®–software that guarantees an easy handling of the analyzer system and a clearly arranged representation of the results of measurements. So the user is informed about the progress of the measurements at any time. All controls needed for the routine procedures of the FAN ci2, as recording of sample data, start of measurement, evaluation and documentation of the results are easy available. All relevant system parameters are observed continuously and any disturbances in the process reported immediately. By selecting only a few system parameters, the FAN ci2 is adaptable to different questions. Via standard data interfaces like GDT, HL7 or ASTM the software can be connected to practise or hospital EDP systems easily. System configuration The FAN ci2 only consists of one unit that includes the acquisition unit and the gas management system. The gas sample–ports for the breath bags are located in front of the device. There are only two connections necessary: the power supply and the connection to the Personal Computer. The software communicate with the components of the device via USB. Simple and secure handling by in the hardware integrated sample recognition system compact design and neat layout of controls internal control with fail-save CAN bus heated gas path to eliminate residual moisture low stoppage times and service costs by internal status checks for early failure diagnosis Optical system with integrated thermostat, optimized for the measuring process new efficient IR–sources modified light modulation, optimized to the signal processing and, due to this markedly smoother output signal with lower drift insensitive to nuisance gases by higher selectivity
