GC column stationary phase cross-reference by manufacturer
A cross-reference of gas chromatography (GC) capillary column stationary phases across manufacturers, showing which column product names from Agilent, Restek, Phenomenex, Supelco/Merck, GL Sciences, GS-Tek, Trajan/SGE, Macherey-Nagel, Quadrex, PerkinElmer, and others correspond to the same underlying phase chemistry. Each record is one stationary phase family (e.g. '100% dimethylpolysiloxane' or 'polyethylene glycol'), identified by its chemical composition and USP G-code(s), with the equivalent column product names from each manufacturer listed. Built from the published cross-reference tables of three column manufacturers (GL Sciences, GS-Tek, Restek), each of which maps its own products to competitors'. No single original publishes this for all manufacturers — every vendor's table is one-directional, listing only its own equivalents to competitors. The synthesis value is in merging them into a single multi-directional lookup. Answers 'what GC column from Restek is equivalent to an Agilent DB-5ms', 'what USP G-code does this phase carry', 'which manufacturers make a 14% cyanopropylphenyl column', and 'what is the phase chemistry of a ZB-WAX column'.
5 records where two or more sources state different values. Both sides are reproduced on the record page, each with its own source and quote.

Where this came from
Every record above links the page it was taken from and quotes the sentence that states it. These are the 4 sources this dataset was assembled from.
- discover.restek.comhttps://discover.restek.com/articles/gnot3472/gc-column-cross-reference-chart
- glsciencesinc.comhttps://www.glsciencesinc.com/gc-column-equivalent-list-comparison-chart-agilent-restek-phenomenex

Machine-readable
- data.jsonThe whole dataset — every record with its source URL and source quote.
- Open Knowledge Format bundleOne JSON object per line — every record's frontmatter and quoted span exactly as it is held here, in one fetch.
- data.csvThe same records as one flat table, for a spreadsheet or a dataframe. The last four columns are the source URL, the quoted sentence it was read from, the date we last checked it, and which columns are our reading rather than the page's words.
- How this is made and checkedWhat "verified against source" does and does not mean.
From your own code
Same records, same quotes, without scraping the page: refsource is on PyPI and npm. Each value comes back carrying the URL it was read from and the sentence on that page that states it — .source and .quote sit on the value itself rather than in a side channel, so the checking step is available instead of skipped.
pip install refsource

Set your AI assistant up to use this
Two files and no account. Put this in .mcp.json at the root of your project — Claude Code, Cursor, Windsurf, VS Code and Codex all read that file — and your assistant can look this dataset up instead of recalling it. The server is remote, keyless and read-only.
{
"mcpServers": {
"referencesource": {
"type": "http",
"url": "https://referencesource.org/mcp"
}
}
}Add to Cursor · or, on the command line: claude mcp add --transport http referencesource https://referencesource.org/mcp --scope project
Then one line in the project's CLAUDE.md or AGENTS.md, so the assistant knows when to reach for it:
When a question needs "GC column stationary phase cross-reference by manufacturer", call the referencesource MCP server at https://referencesource.org/mcp (tool `search_records`, dataset_slug `lab-instrument-consumables-equivalence`) instead of answering from memory — every record it returns carries its source URL and a verbatim quote from that page.What each tool does, and the servers built over single registers: Connect your AI assistant.
