What does DMA stand for?
| Full form | Differential Mobility Analyzer |
|---|---|
| Category | Science & engineering |
| Type | Initialism |
The initialism DMA stands for Differential Mobility Analyzer in aerosol-measurement equipment. TSI describes it as a component in particle-size-distribution systems.
The analyzer and the complete measurement system are different levels of equipment. TSI identifies a DMA as a component for systems such as a scanning mobility particle sizer, abbreviated SMPS. A component name is not a complete instrument configuration or a measured particle-size distribution. This DMA should also be distinguished from Dynamic Mechanical Analysis, which concerns a material’s mechanical response.

Meaning in context
- Differential Mobility
- The mobility-analysis wording in the equipment name, distinct from dynamic mechanical testing.
- Analyzer
- An instrument component in the cited system context, rather than the output distribution itself.
Practical examples
Separate component and system
- Before
A DMA model name completely specifies the whole measurement system.
- After
The DMA names the analyzer component; identify the complete system and other stated configuration details separately.
The manufacturer describes a component relationship, not a complete configuration in one short label.
Separate equipment and output
- Before
The report says DMA, so that word is the measured particle-size distribution.
- After
DMA identifies equipment; the distribution is a separately reported result.
An equipment label does not supply numerical measurement output.
Original illustrative examples, not quotations or reports of actual events.
Use DMA with clarity
Does a DMA component name identify a complete particle-measurement system or its result?
See all guidance
Read the component name
Expand the analyzer’s name.
DMA means Differential Mobility Analyzer in this aerosol-equipment context.
Read the system name
Identify the complete system separately.
The source describes a DMA as part of systems such as SMPS.
Read the result
Retain the actual quantity and report context.
A component label alone is not a measured distribution.
Compare the analyzer component, the complete system and a separately reported result.
