User Interface

The Chemotion ELN consists of different panels that are combined in the main application page:

Main Page

whole window

Action Bar

The action bar on the top contains symbols for essential actions that are either very important for setting up or using the Chemotion ELN. The action bar is always located just below the browser window.

Collection Bar

The collection bar is located on the left below the action bar and used to navigate through the collections. It can be toggled on/off.

Management Level

The management level can be opened using the button in the collection bar. The management level enables the creation, deletion and organization of collections.

Element Bar

The element bar is to the right of the collection bar. It shows the elements ** Sample**, ** Reaction**, ** Wellplate**, ** Screen** and Research Plan assigned to the selected collection. You can find more details in the Elements section.

Detail Modal

The detail modal or detail window is opened by clicking on the desired element. It shows the information which are stored on the corresponding element or are available through databases. The modal / window can be set to full screen mode.

Detail Tab#

To organize the information within the detail modals, tabs were introduced. These enable the information to be structured and displayed as folders.


  • Samples
    Samples are the smallest organizational unit of this Chemotion ELN. They describe the physical unit of a chemical compound used for a synthesis or other projects. The sample is described by e.g. the molecular structure, the amount and the properties of the compound used (such as the purity). If a chemical compound with the same molecular structure is used several times, several samples are generated, each with the same molecular structure as a feature.
  • Reactions
    Reactions form the core of the Chemotion ELN, as reactions can be used to plan the chemists' experiments. The reactions are characterized by the use (starting material, reagents) and the receipt of samples (products).
  • Wellplates
    Several samples can be arranged in wellplates so that they can be combined according to an application in biology.
  • Screens
    A screen is the overview of a biological experiment that is carried out with several samples (usually organized by wellplates).
  • Research Plan
    A research plan is a generic element that can be used in a flexible manner to describe in particular processes. The research plan combines functions for text, tables, images and other information and allows the assignment of other elements such as molecules and reactions.
  • Others
    The Chemotion ELN in its first, pure chemistry version included only the elements described above. In the meantime, a more flexible use of the Chemotion ELN allows the definition of additional elements which can then be added to the Chemotion ELN by the supervising admin.


  • Split :** Split ** is an action that can be carried out according to the physical division of a sample into subsets (a certain amount of a chemical compound). A ** split ** represents the removal of a subset from a sample and depicts this by generating a new sample with the same properties as the original sample. The split action can be traced by numbering the newly created sample based on the original sample.
  • Copy: In contrast to the ** Split **, the ** Copy ** action means that a copy of only the molecular structure (including the parameters dependent on the molecular structure such as molecular weight) is made. The copy has no relation to the original sample and can be saved under a new name.
