The amount of CO 2 emitted from a coal-fired power plant (CFPP) is measured by continuous emissions monitoring systems (CEMS) permanently installed in the exhaust smokestack. Both the CO 2 concentration and the bulk flow are continuously measured by CEMS

Spinning rotor gauges (SRGs) are widely used as transfer standards in inter-laboratory comparisons and as secondary standards by calibration laboratories. In both of these applications, it is necessary to ship the SRG for calibration, often internationally

The National Institute of Standards and Technology (NIST) has a wide range of Standard Reference Materials (SRMs) which have values assigned for legacy organic pollutants and toxic elements. Existing SRMs serve as homogenous materials that can be used for
Solid phantoms that serve as a proxy for human tissue and provide a convenient test subject for optical medical imaging devices. In order to determine quantitative performance of a given system, the absolute optical properties of the subject must be known

Most instruments for measuring fluid density are not absolute instrumentsthey must be calibrated with one or more fluids of known density. The selection of appropriate calibration fluids is vital to achieving low uncertainty in a measurement. Also
The use of naturally derived substances for therapeutic use has a longstanding history of success. Therapeutic monoclonal antibodies can be thought of in a similar light as they harness the highly evolved specificity of adaptive immunity to fight disease
Reference Materials are well-characterized, homogeneous, and stable samples that can be used to understand measurement performance. The Genome in a Bottle Consortium is developing whole human genome DNA Reference Materials from large batches of DNA
The SRM Spotlight is a newsletter published by the Office of Reference Materials for users of NIST standard reference materials. The Spotlight announces new reference materials and provides information about their use. In addition, this newsletter contains

Although nutraceuticals and functional foods seem to be ill-defined terms, both are often used to indicate a food that contains compounds providing benefits beyond basic nutrition, often with the expectation that these compounds are protective against
The NIST Microelectromechanical Systems (MEMS) 5-in-1 Reference Materials (RMs) were developed to assist users in validating their use of five documentary standard test methods. A Reference Material can be defined as a material whose property values are
