LIMS vs ELN is the question a small lab asks when the vendor's demo shows a notebook and a sample record on the same screen. An ELN, an electronic lab notebook, keeps what a scientist did and thought, in order, signed; a LIMS keeps what happened to a sample, in states, signed. ELN vs LIMS is therefore a question of which record the lab is judged on: a research lab is judged on its notebook, a testing lab on its samples. LIMS and ELN together is what a lab that does both keeps, and the LIMS ELN question resolves when one record links to the other rather than copies it. This page is that resolution, and the free results review sheet on this site works a figure the LIMS side reports, the review load, from the lab's own numbers with no account.
What each record keeps
The ELN keeps the experiment: the plan, the observations, the deviations, the conclusion, page by page and signed. The LIMS keeps the sample: accession, tests, lots, instruments, results, review, retention. A result can live in both, but its home is the LIMS if a client or a regulator will ask for it and the ELN if only the scientist will.
LIMS, ELN or both: which to keep first
A testing laboratory that issues results keeps the LIMS first, because the sample record is what the accreditor reads. A research group keeps the ELN first, because the notebook is what the reviewer reads. A lab that does both keeps the LIMS for the samples and the ELN for the experiments, and links the experiment to the sample rather than retyping either.
When the ELN LIMS overlap is one record
Small-lab products increasingly keep the notebook page against the sample it was about, which is the honest resolution of the ELN LIMS overlap: one record, two views. Limslane Pro keeps the sample record and the notes against it; the free sheets on this site work the sample side's figures either way.
Questions people ask about lims vs eln
What is the difference between LIMS and ELN?
The ELN keeps the experiment, in order and signed; the LIMS keeps the sample, in states and signed. A testing lab is judged on the second.
Does a small lab need both LIMS and ELN?
Only if it both issues results and runs experiments; then keep the LIMS for samples and the ELN for experiments, linked rather than copied.
Which should a testing lab keep first?
The LIMS: the sample record is what the accreditor and the client read. The paid plan on this site keeps it at one flat price.
