文档介绍：A 21st-Century Chemistry Lab The new Advanced Chemical Sciences Laboratory (ACSL) at the National Institute of Standards and Technology in Gaithersburg, Md., was built to house research programs that establish and ensure accuracy for millions of chemical meas- urements made in the United States. The $75 million, 18,588 square-meter (200,000 square-foot) building is a state-of-the-art research facility with advanced features that will allow NIST scien- tists to extend their capabilities and increase the efficiency and impact of their world-class research in biotechnology, analyti- cal, environmental, clinical, and other related chemical measurements and standards in a safer, more healthful work setting. Building materials and equipment select- ed for the new build- ing were chosen carefully. For example, fume hoods, lab benches, and other lab equipment do not contain elements that could contaminate analyt- ical samples. NIST chemists now will be able to develop new standards for measuring extremely small quantities of elements such as lead, which is implicated in environmental and health problems. The building also features high-efficiency air han- dling, precise temperature and humidity control, an uninterruptible power supply, an emergency back-up generator, and a wiring backbone that will satisfy data transmission needs well into the 21st century.
