absorptiometer

[əb‚sȯrp·tē′ä·məd·ər]
(analytical chemistry)
An instrument equipped with a filter system or other simple dispersing system to measure the absorption of nearly monochromatic radiation in the visible range by a gas or a liquid, and so determine the concentration of the absorbing constituents in the gas or liquid.
A device for regulating the thickness of a liquid in spectrophotometry.

Based on product, the global body composition analyzers market is segmented into Bioimpedance Analyzers (BIA), Dual-Energy X-ray Absorptiometry (DEXA), Skinfold Calipers, Air Displacement Plethysmography (ADP), and Hydrostatic Weighing, wherein the bioimpedance analyzers segment dominates the market with 40.
More importantly, "the minor areal BMD changes detected by dual-energy x-ray absorptiometry did not reflect the underlying structural deterioration seen with high-resolution peripheral quantitative CT Although dual x-ray absorptiometry is the current clinical gold standard for skeletal assessment of fracture risk, it does not capture bone geometry, microarchitecture, or biomechanical properties, which also contribute to fracture risk," Dr.
