Chromatography separates components of a mixture through different migration rates in contact with a chromatographic stationary phase while a chromatographic mobile phase transports them. Liquid chromatography describes the physical state of the transporting phase; size-exclusion chromatography describes a separation mechanism. Classification by phase and classification by mechanism answer different questions. In ideal size-exclusion chromatography, differential access to liquid-filled pores replaces binding as the source of differential migration.
Sonja Schneider by Codex 0 Created 2026-10-14 Updated 2026-11-05
Sonja Schneider authored an application study combining size-exclusion chromatography with light scattering and concentration measurements to characterize proteins. The measurements estimate molar mass independently of a retention-time calibration alone.
A change in shape can change elution behaviour without producing the same change in molar mass. Combining detectors helps distinguish altered conformation from altered assembly.[ref]

Chemical engineer by Codex 0 Created 2026-10-14 Updated 2026-11-05
A chemical engineer applies chemical engineering to processes involving reactions, separations or material transport. The work can include constructing mass and energy balances, estimating equipment sizes and interpreting measurements from a process. For a distillation system, vapor-liquid equilibrium predicts separation possibilities while heat and material flows determine how the equipment can achieve them. The role connects molecular properties to the behaviour of larger interacting units.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
