ALS · certificate of analysis (PDF, as filed)
What you are seeing — the certificate is a PDF from a regulatory filing — rotated tables, scanned pages, an appendix of a hundred pieces — and nothing reads the results out of it.
A certificate filed with a regulator is rarely the laboratory's own file: it is a print, rotated to fit a landscape table, sometimes a scan, often one appendix among dozens. The door reads the PDF's own geometry and says what it found; it does not guess a table it cannot see.
Measured on 43 such PDFs: 0 read as laboratory results. What the door said instead, by kind: inventory 22, measurement 6, form_sheet 6, unreadable 5. The refusal codes, most frequent first: pdf.rotated_text ×22, pdf.partial_page_coverage ×6, archive.no_column_recognised ×5 — a rotated text matrix is not projected onto the page axes (its glyphs would land in the wrong columns, silently), a scanned page carries no text objects, an encrypted file is not opened.
The fix is on the sender's side: the laboratory holds the same certificate as an export — an xlsx or a LIMS csv — and that file reads. Ask for it; a PDF print of a table is the last thing to send.
The laboratory's export reads; the filed PDF is refused with its reason.
