A technician performs densitometry on a photographic film sample.

Definition

1. Noun:
   • The measurement of optical density: Densitometry is the scientific technique of determining the optical density of a material, typically by analyzing how much light it transmits or absorbs.
   • A quantitative analysis method: It refers to the process of measuring the concentration or density of a substance based on its light-absorbing properties.

Usage Examples

• Noun:
  • The lab report included densitometry data to quantify the protein bands on the gel.
  • Densitometry is commonly used in photography to analyze the density of film negatives.

Advanced Usage

• "X-ray densitometry": A specific application for measuring bone mineral density.

  • The patient underwent X-ray densitometry to assess for osteoporosis.

• "Densitometry analysis": The process of evaluating data obtained from a densitometer.

  • The researcher spent the afternoon on densitometry analysis of the chromatogram.

Variants and Related Words

• Densitometer (n): The instrument used to perform densitometry.

  • She calibrated the densitometer before taking measurements.

• Densitometric (adj): Relating to or obtained by densitometry.

  • The densitometric readings were consistent across all samples.

Synonyms

• Optical density measurement
• Absorptiometry (in specific contexts like bone densitometry)

Related Phrases

• "To perform densitometry": To carry out the measurement.

  • The technician will perform densitometry on the sample.

• "Densitometry reading": A single result or value from the measurement.

  • A higher densitometry reading indicates greater absorption of light.
