uranalysis, urinalysis
(medicine) the chemical analysis of urine (for medical diagnosis)
(medicine) the chemical analysis of excrement (for medical diagnosis or for paleontological purposes)
an electrochemical method of chemical analysis
quantitative analysis, quantitative chemical analysis
chemical analysis to determine the amounts of each element in the substance
spectrographic analysis, spectrometry, spectroscopic analysis, spectroscopy, spectrum analysis
the use of spectroscopes to analyze spectra
separation of substances in solution by means of their unequal diffusion through semipermeable membranes
dating, geological dating
use of chemical analysis to estimate the age of geological specimens
the measurement of changes in weight as a function of changes in temperature used as a technique of chemically analyzing substances
colorimetric analysis, colorimetry
quantitative chemical analysis by color using a colorimeter
volumetric analysis
quantitative analysis by the use of definite volumes of standard solutions or reagents
volumetric analysis
determination of the volume of gases (or changes in their volume) during combination
gravimetric analysis
quantitative analysis by weight
apheresis, pheresis
a procedure in which blood is drawn and separated into its components by dialysis; some are retained and the rest are returned to the donor by transfusion
haemodialysis, hemodialysis
dialysis of the blood to remove toxic substances or metabolic wastes from the bloodstream; used in the case of kidney failure
mass spectroscopy
the use of spectroscopy to determine the masses of small electrically charged particles
microwave spectroscopy
the use of spectroscopy to study atomic or molecular resonances in the microwave spectrum
potassium-argon dating
geological dating that relies on the proportions of radioactive potassium in a rock sample and its decay product, argon
carbon dating, carbon-14 dating, radiocarbon dating
a chemical analysis used to determine the age of organic materials based on their content of the radioisotope carbon-14; believed to be reliable up to 40,000 years
rubidium-strontium dating
geological dating based on the proportions of radioactive rubidium into its decay product strontium; radioactive rubidium has a half-life of 47,000,000,000 years
Type of:
an investigation of the component parts of a whole and their relations in making up the whole
