Chromatogram vs. Chromatograph: What's the Difference?
Edited by Huma Saeed || By Sawaira Riaz || Updated on October 12, 2023
A chromatogram is the visual output or pattern produced, while a chromatograph is the instrument or apparatus used for chromatography.
Key Differences
The terms "Chromatogram" and "Chromatograph" might seem alike, but they denote different aspects within the realm of chromatography. A chromatogram refers to the visual representation, often on paper or a screen, showcasing the result of the separation process of a sample.

Conversely, the term "Chromatograph" is reserved for the actual equipment or instrument utilized in the process of chromatography. This apparatus facilitates the separation of mixtures into their individual components based on their interaction with a stationary phase.

In simpler terms, one can think of the relationship between a Chromatogram and a Chromatograph similarly to the relationship between a printout and a printer. The chromatogram is the "printout" or output, while the chromatograph is the "printer" or tool.

To delve a bit deeper, a chromatogram showcases peaks and valleys. These peaks correspond to different components of a sample, allowing scientists to identify and quantify them. The chromatograph, on the other hand, is equipped with detectors, columns, and other parts to perform the separation and produce a chromatogram.

Conclusively, while both terms are intrinsically linked and vital to the science of chromatography, the chromatogram is the result or outcome, and the chromatograph is the mechanism facilitating this result.
