Squeeze Play Tem-Pres Pressure Intensifiers
Research engineers at Detroit Edison Co. are shown with a model of the company's 3 2 0 0 - M W Monroe, Mich., plant, the world's largest coal-fired electric generating plant. Records are made of the smoke plumes from the model chimneys. This is part of the laboratory work at Detroit Edison where a full complement of sophisticated analytical in strumentation is used for the analyses of air, water, fuels, and materials
Burtis, W. F. Johnson, M. L. Bauer, D. G. Lakomy, R. K. Genung, and C. D. Scott. Details of the instrument de sign, operating characteristics, and an alytical capabilities are reported in a paper scheduled for publication in the September issue of Clinical Chemis try.
Centrifuge/ Spectrophotometer Combination William C. Deal, Jr., professor of biochemistry, and Jason Wei, postdoc toral fellow at Michigan State Univer sity, have developed an improved farultraviolet scanning ultracentrifuge. The machine's optical system and de tector, controlled by computer, is ca pable of using ultraviolet light of ex tremely short wavelengths (in the 200-nm range). For light absorption studies aimed at understanding mo lecular structure, interactions, and composition, the new system is 10-20 times as sensitive as conventional ultracentrifuges. The apparatus provides a valuable tool to study the structures of pro teins. Quantities of material as small as fractions of a microgram can be an alyzed and assayed. Spinning at 60 000 rpm, one to five samples are automatically exposed to a light beam.
A computer controls the beam and de tector, and automatically records within a few microseconds light ab sorption and numerical and graphic data. Design and construction of this in strument has been a five-year project, funded by the National Science Foun dation. Experiments that once re quired hours can now be performed in minutes, with more accurate results.
Market Study Predicts Heavy Growth in Separations In a new study published in April of this year, Creative Strategies, Inc., predicts that demands for environ mental monitoring, clinical lab testing, and research and development will provide a worldwide market for ana lytical and process analytical instru mentation of $2.1 billion by 1981. The separation market, with an average annual compound growth rate of 15%, is predicted to overtake the currently strong spectrometer segment by 1981. The impact of microprocessors will be such that by 1981 more than 60% of sales in analytical instrumentation will incorporate this technology. Beckman, Perkin-Elmer, and Varian Assoc, account for 26% of the worldwide mar ket in this industry which is character ized by fragmentation and much com petition according to CSI.
The compact Tem-Pres inlensilier. originally designed lor laboratory use. occupies minimum Moor space. The sell-contained unit automatically accepts low-pressure gas Irom an external source and compresses it to elevated pressures. Gauges indicating hydraulic drive pressure as well as inlet and intensified gas pressures are mounted on the cabinet panel. Tem-Pres constructs the units ol high-yield, vacuum-melt steel lorging. heattreated to exacting specifications.
