Autosampler – Definition & Meaning

An autosampler is a laboratory instrument that is used to automatically load samples into an analytical instrument for analysis. It is a crucial tool in many scientific fields, including chemistry, biology, and environmental science. In this article, we will explore the definition and meaning of autosampler, its origin, associations, synonyms, antonyms, and example sentences.


An autosampler is a device that automatically loads samples into an analytical instrument. It is used to increase the efficiency and accuracy of sample analysis by reducing human error and increasing sample throughput. Autosamplers are commonly used in gas chromatography, liquid chromatography, and mass spectrometry.


The term autosampler was first coined in the 1970s when automated sample injection systems were introduced in gas chromatography. The first autosamplers were designed to load samples into gas chromatographs, but over time, they were adapted for use in other analytical instruments.

Meaning in different dictionaries

According to Merriam-Webster, an autosampler is “an automatic device for introducing a sample into an instrument, especially one that analyses chemical compounds.”
Oxford Languages defines an autosampler as “an automated device used to introduce samples into an analytical instrument for analysis.”


Autosamplers are commonly associated with analytical instruments such as gas chromatographs, liquid chromatographs, and mass spectrometers. They are also associated with laboratory automation and high-throughput sample analysis.


Synonyms for autosampler include sample injection system, sample introduction system, and sample handling system.


There are no direct antonyms for autosampler, but manual sample loading can be considered the opposite of automated sample loading.

The same root words

Autosampler is derived from the words auto, meaning automatic, and sampler, meaning a device for collecting and analyzing samples. Other words derived from the root word sampler include sample, sampling, and sample preparation.
