Chemical analysis determines matter's physical properties and composition. Classical analysis uses only balance, relying on chemical reactions. Instrumental analysis employs various instruments for analysis. Quantitative analyses include gravimetric and volumetric methods
Written for applied mathematicians interested in differential equations. Combines theory with practical solutions and analysis methods. Includes new problems, updated figures and examples. Mainly intended for first/second year undergraduate students
AES determines element quantity using light emitted from flame or plasma. Each element has unique spectral line due to different atomic arrangement. Robert Bunsen and Gustav Kirchhoff established this chemistry tool
XRF analyzes elements by measuring characteristic fluorescent radiation emitted by them. It operates in wavelength-dispersive (WDXRF) or energy-dispersive (EDXRF) modes. Each element has unique atomic structure and emits specific X-ray wavelength
Consensus estimate is a forecast of company earnings based on analyst predictions. Estimates are derived from pool size and analyst coverage. Analysts use financial statements and market sentiment for predictions
PEGs are addition polymers of ethylene oxide and water. Molecular weight ranges from 200 to 9500. Below 700 MW are clear liquids, 700-900 MW are semi-solids, above 1000 MW are solids
