Detection and tabulation of mass-selected ions are the primary means of data acquisition for mass spectrometers. Previous detection systems have been limited in dynamic range, or in data throughput, so that inefficient and limited use of the ion information resulted. Analysis of the statistical properties of randomly arriving ions and the use of state-of-the-art technologies have led to the development of an enhanced ion detection system (IDS) for a triple quadrupole mass spectrometer (TQMS). An adaptive sampling technique maximizes data throughput without distorting relative error or limiting dynamic range. This microprocessor-based system measures flux rates from 10 to the zero power to 10 to the 9th power ions per second up to a maximum relative error of 1%; sampling periods are reduced to their statistically defined minimums. Preliminary tests have validated the correctness of the IDS design along with its capability for on-line customized operation through the use of powerful and flexible high-level software. (Author).

Offering a viable solution to the long-standing problem of estimating the abundance of rare, clustered populations, adaptive sampling designs are rapidly gaining prominence in the natural and social sciences as well as in other fields with inherently difficult sampling situations. In marked contrast to conventional sampling designs, in which the entire sample of units to be observed is fixed prior to the survey, adaptive sampling strategies allow for increased sampling intensity depending upon observations made during the survey. For example, in a survey to assess the abundance of a rare animal species, neighboring sites may be added to the sample whenever the species is encountered during the survey. In an epidemiological survey of a contagious or genetically linked disease, sampling intensity may be increased whenever prevalence of the disease is encountered. Written by two acknowledged experts in this emerging field, this book offers researchers their first comprehensive introduction to adaptive sampling. An ideal reference for statisticians conducting research in survey designs and spatial statistics as well as researchers working in the environmental, ecological, public health, and biomedical sciences. Adaptive Sampling: Provides a comprehensive, fully integrated introduction to adaptive sampling theory and practice Describes recent research findings Introduces readers to a wide range of adaptive sampling strategies and techniques Includes numerous real-world examples from environmental pollution studies, surveys of rare animal and plant species, studies of contagious diseases, marketing surveys, mineral and fossil-fuel assessments, and more
