Physicochemical Measurements

Physicochemical Measurements: Catalogue of Reference Materials from National Laboratories offers information on chemicals, including their density, magnetic susceptibility, calorimetry, molecular conductance, and thermal conductivity. The catalog first offers information on acidimetry, calorimetry, and spectrophotometry and tristimulus colorimetry. The chemicals examined include potassium hydrogen, boric and benzoic acids, heptane, neopentane, and aluminum oxide. The text then presents data on density, dielectric constants, differential thermal analysis, magnetic susceptibility, and molar conductance. The chemicals evaluated include cyclohexane, kerosene, toluene, chlorobenzene, carbon tetrachloride, potassium nitrate, indium, tin, aluminum, platinum, and potassium chloride. The book discusses the molecular weight of polymers, refractive index, relative humidity, specular spectral reflectance, and surface tension. The text also takes a look at thermal conductivity and emissivity and vapor pressure. The catalog is a dependable reference for readers interested in the composition, characteristics, and reactions of chemicals.

Recommended Reference Materials for Realization of Physicochemical Properties presents recommendations of reference materials for use in measurements involving physicochemical properties, namely, vapor pressure; liquid-vapor critical temperature and critical pressure; orthobaric volumes of liquid and vapor; pressure-volume-temperature properties of the unsaturated vapor or gas; and pressure-volume-temperature properties of the compressed liquid. This monograph focuses on reference materials for vapor pressures at temperatures up to 770 K, as well as critical temperatures and critical pressures; reference materials for vapor pressures at temperatures above 600 K; reference materials for orthobaric volumes (or densities) and critical volume (or density); reference materials for pressure-volume-temperature behavior (gases); and reference materials for pressure-volume-temperature behavior (liquids). The orthobaric volumes are typically related through their reciprocals, the orthobaric densities, by the well-known ""law of rectilinear diameters."" Carbon dioxide is recommended as a test substance for vapor-pressure measurements on relatively high-boiling gases. This book will be of interest to physicists and chemists.

During the past thirty years, companies have recognized the consumer as the key driver for business and product success. This recognition has, in turn, generated its own drivers: sensory analysis and marketing research, leading first to a culture promoting the expert and then evolving into the systematic acquisition of consumer-relevant information to build businesses. Sensory and Consumer Research in Food Product Design and Development is the first book to present, from the business viewpoint, the critical issues faced by business leaders from both the research development and business development perspective. This popular volume, now in an updated and expanded second edition, presents a unique perspective afforded by the author team of Moskowitz, Beckley, and Resurreccion: three leading practitioners in the field who each possess both academic and business acumen. Newcomers to the field will be introduced to systematic experimentation at the very early stages, to newly emerging methods for data acquisition/knowledge development, and to points of view employed by successful food and beverage companies. The advanced reader will find new ideas, backed up by illustrative case histories, to provide another perspective on commonly encountered problems and their practical solutions. This book is aimed at professionals in all sectors of the food and beverage industry. Sensory and Consumer Research in Food Product Design and Development is especially important for those business and research professionals involved in the early stages of product development, where business opportunity is often the greatest.
