Electronic Laboratory NotebookTM

Electronic Laboratory Notebook (ELN) is a highly sophisticated relational database program that is capable of storing and retrieving information on chemical compounds. ELN has an open architecture which permits text, graphics, video, and many other types of objects to be stored into a ELN database. Use the computer keyboard or the Windows clipboard to insert data from your favorite Windows program into ELN and be able to retrieve it with only a few clicks of the mouse. The flexibility and speed of ELN makes it an invaluable tool for the chemical professional.

ELN is structured to allow for the creation of an unlimited number of chemical database files. The user first creates or opens a chemical database file then adds chemical cards to that file (Fig. 1). The only limitation to the number of chemical cards that each chemical database may contain is the available disk storage space. Once a chemical card has been saved in a chemical database file "spectra cards" can be linked to it. Each chemical card can have links to many different types of spectral information. ELN includes an advanced indexing feature that lets the user quickly view and retrieve a chemical card and all associated spectra cards that are linked to it.

One of the most powerful features of ELN is its ability to import and store information from other Windows programs. ELN utilizes the Windows Clipboard and Object Linking and Embedding (OLE) to exchange objects between other Windows programs and ELN. This powerful feature lets the user either link (references) or embed objects into the database from other Windows applications such as Microsoft Excel, Word for Windows, Lotus 1-2-3 for Windows, and Corel Draw. A chemical card as well as all the spectra cards can contain a combination of both linked and embedded objects of the same or of different types. A few examples of the variety of objects that can be pasted into ELN are:
