Design gravimetric standards with real uncertainty, plan serial dilutions, track your COAs and expiry, and print professional certificates that show their own working — free, with a free account. In return, we're building the first measured reference library for LUMA VUV data, from standards labs already have on the shelf.

What doesn't exist yet is a reference library for LUMA data — so today each lab builds its own from scratch, one compound at a time, and none of that effort is shared.
We're building that library from measured spectra rather than predicted ones, working toward making relative response factors usable — so a lab could quantify compounds it doesn't hold a calibration standard for. Which is most of them.
New analytical technology rarely fails on the science. It stalls because someone has to do the unglamorous part first — develop the methods, run the standards, gather the reference data — and that work is slow and expensive, and nobody is funded to do it. We're taking that role on. But the reference material has to come from the labs that already have it sitting on a shelf.
| We'd love | Why |
|---|---|
| Expired or out-of-date standards | Identity doesn't expire — only certified concentration does. Expired material is perfectly good for a reference spectrum, and you'd otherwise pay to dispose of it. |
| Surplus or discontinued lots | Same reason. Anything sitting unused. |
| Near-empty bottles | We need very little — a couple of millilitres is plenty. |
| Sulfur species and heavier aromatics especially | These are the hardest to obtain and the least well covered. |
We'll take anything identifiable. If you're unsure whether something is useful, it probably is — tell us and we'll say.
Anything identifiable helps — but these are the priorities, and when you submit you can tap a compound from this list to add it in one click, with its CAS already filled in.
The C3–C4 mercaptan isomers are the top priority: they're near-identical to the detector, so they can only be captured with a real, measured standard.
Mercaptans (methyl, ethyl, n-/iso-propyl, n-/sec-/iso-/tert-butyl) · sulfides & disulfides (dimethyl, diethyl, dimethyl disulfide) · thiophenes (thiophene, methylthiophenes, benzothiophene, dibenzothiophene) · carbon disulfide · carbonyl sulfide
Aromatics (BTEX, trimethylbenzenes, naphthalenes, biphenyl) · oxygenates (MTBE, ETBE, TAME, alcohols, ketones, ethers) · olefins, naphthenes, and the n-alkane ladder (C5–C12) plus isooctane
Nitrogen compounds (pyridine, quinoline, aniline) · heavier aromatics / PAH (fluorene, phenanthrene, pyrene) · certified refinery-gas, natural-gas and sulfur-in-gas mixtures
You're being asked to hand chemicals and contact details to a website. You should be skeptical. Here's everything you'd need to check us out, and the things we deliberately don't do.
We will never ask you for: a payment or card number · a bank or purchase-order detail · your employee ID · remote access to your systems · your instrument data.
You create a free account — an email and password on this domain only — so your workgroup can share the tools and certificates. We store only your account: your name, company, site and workgroup membership, with the password hashed so we can't read it. Your inventory, COAs and certificates are never on our servers — they stay in a folder you choose on your own machine. We will never email you asking for your password, and we'll never ask for it anywhere but a page you navigated to yourself.
Design a multi-component calibration standard in % w/w, mg/kg, % w/v, mg/L or % v/v. It returns a purity-corrected weigh sheet; you enter what the balance actually read and it back-calculates true concentrations with uncertainty — never assuming you hit the target. Every step is shown with your own numbers, so you can check the arithmetic rather than trust it.
Work down from a certified stock through as many levels as you need. It shows the weights at each step and warns when a step needs less material than a balance can weigh reliably — the error that quietly ruins low-level standards.
Warns when an analyte boils too close to your solvent to resolve, when two analytes will likely co-elute, and suggests solvents that clear everything in your blend.
Each standard gets a unique ID, the person who prepared it, created and expiry dates, storage requirements derived from its components, your balance and its calibration status, and a signature block for preparer and checker. Save it to a folder on your own machine.
Drop in a certificate PDF and it reads the compound, CAS, lot, purity and expiry off it — in your browser; the file is never uploaded. Tracks what you hold by room, cabinet and shelf, warns before anything expires, and exports CSV for your LIMS.
Physical properties, storage guidance with the reasoning shown, and practical notes on making a standard with each compound.
Create an account and you get a workgroup; invite colleagues and you share the tools and certificates, and see what standards are held at which site. We hold only the accounts — your inventory and certificates stay in your own folder.
These tools are in beta. They work and we use them daily, but they're still being built, and you'll find rough edges. Tell us about them — that's genuinely useful to us.
They'll become a paid subscription eventually. We'd rather say that now than surprise you later.
If you contribute a standard, you keep access free. Free through the whole beta, and a permanent founding-contributor tier after that. People who help build this shouldn't have to rent it back.
Contributors can look up any compound in the reference library and see its measured spectrum — enough to check whether what you need is covered, and to compare against your own data.
The library isn't published as a downloadable dataset, and it isn't open-licensed. It represents a large amount of instrument time and material, and it's what makes the identification and quantitation software work. Being able to see it is free for contributors; building products on top of it is what the subscription is for.
You're contributing material, not intellectual property. Nothing you send transfers any rights in your own methods or data, and we'll never publish your name or your lab's information without asking you first.
