Meaning and Definition
An instrument that measures the intensity or wavelength of fluorescence.
A photoelectric device used in chemistry, biochemistry, and environmental science to quantify fluorescent light emitted by a sample, often to determine the concentration of specific substances.
Dialectal Variation
British vs American Usage
Differences
The spelling 'fluorimeter' is common in British English, while American English strongly prefers 'fluorometer'.
Connotations
None beyond the spelling and frequency difference.
Frequency
In American technical literature, 'fluorimeter' is rare; 'fluorometer' is the standard term. In British literature, 'fluorimeter' is more common but 'fluorometer' is also used.

- Using it as a general term for any spectrometer.
- Incorrect plural: 'fluorimeters' (correct) not 'fluorimeter' (as plural).
FAQ
Frequently Asked Questions
Not exactly. A fluorimeter specifically measures emitted fluorescent light, while a standard spectrophotometer measures light absorption. Some instruments combine both functions.
In practical usage, very little. The difference is primarily one of spelling preference ('-meter' vs. '-imeter'), with 'fluorometer' being dominant in American English. Some technical definitions suggest 'fluorimeter' measures intensity and 'fluorometer' measures wavelength, but this distinction is not consistently applied.
No. A fluorimeter requires the sample to fluoresce, meaning it must emit light of a longer wavelength after absorbing light. Non-fluorescent materials will give a null or negligible signal.
A very common application is in water quality testing to measure concentrations of chlorophyll (from algae) or certain pollutants, and in biomedical labs to detect specific DNA sequences or proteins using fluorescent tags.
