A method for sheath flow forming, controlling, and detecting

An elaborated mechanism for sheath flow forming includes flow cell, vacuum pool, sample pool, syringes, valves, and tubes. Firstly the sample is drawn into the sample inlet of flow cell through vacuum generated with one syringe. Then, the sample and buffer are driven to pass the flow cell to form sheath flow by other two syringes. To visualize and evaluate the sheath flow, black ink is used as sample, and optical imaging system is adopted to capture the formed sheath flow. Sheath flows with sample width of 21μm and 37μm in diameter are formed in a flow cell with micro-square hole of the size 0.2mm×0.2mm when the syringes run in different speed.

INCREASED PLANT EFFICIENCY BY ONLINE PLANT ASSET MANAGEMENT

Abstract Asset management in industrial plants has become an important factor for cost efficient production by helping to reduce the effort for maintaining the plant and the plant instrumentation. This results in a higher availability of the production. The highest possible benefit for the customer can be achieved if the asset management is based upon real-time processing of the information already available in the process control system. The integration of the asset management in the process control system is the logical realization of this requirement and creates additional advantages like uniform look and feel, uniform engineering and reduced engineering effort.
