What's the difference between polarimeter and polarimetry?
Polarimeter
Definition:
(n.) An instrument for determining the amount of polarization of light, or the proportion of polarized light, in a partially polarized ray.
Example Sentences:

(11) Anesthetized, adult dogs underwent intravenous glucose loading, and these preliminary in vivo studies resulted in good correlation (r = 0.98) between CSF polarimeter readings and CSF glucose by laboratory assay.
Polarimetry
Definition:
(n.) The art or process of measuring the polarization of light.
Example Sentences:
(1) Cu(2+)-beta-cyclodextrin (1:1) complex has been found by UV, fluorescence and CD spectroscopy, polarimetry and gel electrophoresis to bind reversibly to calf thymus DNA.
(2) Where reaction products are known, photoelectric polarimetry has great advantages in speed, convenience, and cost compared with chromatographic methods for measuring rates of reaction of optically active analytes.
(3) The focus of this paper was to describe the development and testing of a noninvasive true phase optical polarimetry sensing system to monitor in vivo glucose concentrations.

(12) Fluorescence polarimetry was superior to liquid phase immunoprecipitation in respect of performance, ease of operation and cost.
(13) This was determined by measuring the O. D. at 260 and 280 millimicron, the protein concentration by Lowry method and sucrose concentration by polarimetry in 60 fractions.
(14) Unlike conventional polarimetry, the method does not require chemically-pure samples and can be orders of magnitude more economical in material.
(15) These acids were shown by gas-liquid chromatography, mass spectrometry, and polarimetry to be the d(-)3-hydroxy fatty acids.
