densitometer

She took the strips to a photo shop and the photographer let them use a densitometer.

A software densitometer with unlimited sample sites was also included.

The densitometer is basically a light source aimed at a photoelectric cell.

According to the principle of operation of the densitometer, one can have:

A densitometer (as usually defined) measures the lightness or darkness of the sample being tested.

That would have been easy at home; I could rent a magnetic resonance densitometer to map their insides.

In 1975, X-Rite introduced its first densitometer for photographic printing use.

The gels were scanned with a laser densitometer.

The rover carried a dynamic penetrometer and a radiation densitometer.

Relative intensities were determined by using a scanning densitometer on X-ray films exposed for 2, 16 and 48 h.

The corresponding measuring device is called a densitometer (absorptiometer).

Mr. Stewart had been dismissive about this use of a densitometer, which measures optical density by comparing a darkened area with a white area.

Densitometer measures light transmission through processed photographic film or transparent material or light reflection from a reflective material.

The other boom carried a backscatter densitometer that was used to infer the density of the lunar near-surface regolith.

It permitted the entire range of scattered intensities to be recorded on the film with a subsequent densitometer scan providing the relative scattered intensities.

A densitometer is a device that measures the degree of darkness (the optical density) of a photographic or semitransparent material or of a reflecting surface.

An experienced dermatologist should examine the scalp under magnification (preferably with a device called a densitometer) to assess the degree of miniaturization of the hair follicles.

The plates were developed with high performance thin layer chromatography and read with a scanner densitometer (Shimadzu CS 920).

The centre is equipped with a mammography system, an ultrasound machine, coloscopy systems and bone densitometer that measures lumbar and pelvic bone density.

The hospital has a 24/7 Emergency Department, a diagnostic imaging department that includes a CT scan, an ultrasound, a digital X-ray, and a bone densitometer.

Quantitation was performed using a 300A Computing Densitometer (Molecular Dynamics, CA, USA).

If a more objective evaluation was required, a densitometer can be used to compare the density of the colour patches in the LAD frame with Kodak's published guidelines.

If you have not read or heard much about them, that is probably because their main quarrel seemed to be over whether it is proper to use a densitometer with thin layer chromatography.

This allows zymoblots to be carried out in one place, where a densitometer may not be available, and taken or sent to another place to be quantitatively assayed by densitometry.

Initially working at the division of Astronomy and Physics at the CSIRO, he developed a multi-exposure technique to observe potential flare stars, using a scanning densitometer.
