## Definition

a machine or a person that examines something in detail to find out what it is made of or how it works.

For teachers: a person or device that performs a systematic examination of data, substances, or complex systems to determine their constituent parts or underlying principles.

## Examples

- The lab technician used a blood analyzer to check the sample.
- The software includes a built-in network analyzer to help IT staff identify where the connection is slowing down.
- By feeding the raw data into a sophisticated spectrum analyzer, the researchers were able to isolate specific frequencies that had previously been obscured by background noise.

## Pitfalls

- Not "The analyzer of the data was wrong." but "The analysis of the data was wrong." — Learners often use 'analyzer' (the tool/person) when they mean 'analysis' (the process or result).

## Usage notes

- Commonly used in technical, medical, and computing contexts; the spelling 'analyser' is preferred in British English.
