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.

Results: Of the total 108 children selected, 18(16.6%) had to be excluded due to poor nutrition status or deranged serum chemistry, while in 4(3.7%) children Dual Energy X-ray Absorptiometry scan was not done on technical grounds.
Researchers used dual x-ray absorptiometry scans to assess bone mineral density (BMD) at the lumbar spine, femoral neck, and hips of the study participants and assigned the women a Trabecular Bone Score, which indicates the quality of bone structure, based on their BMDs.
These methods include: hydrodensitometry (HW), dual-energy x-ray absorptiometry (DXA), isotope dilution (ID), skinfold thickness (SKF) body mass index (BMI), near-infrared interactance (NIR) and bioelectrical impedance analysis (BIA) (9,10,22).
The global bone densitometers market segmentation is based on technology (axial bone densitometry, dual energy x-ray absorptiometry, quantitative computed tomography, peripheral bone densitometry, single energy x-ray absorptiometry, dual energy x-ray absorptiometry, radiographic absorptiometry, quantitative ultrasound, peripheral quantitative computed tomography), and end users (hospital-based bone densitometers, clinic-based bone densitometers).
The new study extends the findings from the earlier research using dual X-ray absorptiometry, a more rigorous method of measuring body composition.
Quality is ensured for meat processed on the production line by the use of the company's third generation Dual Energy X-ray Absorptiometry (DEXA) technology that discriminates between fat and lean portions of 100 percent of the throughput products.
