We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Sedimentation — The entry omits Type 4 (compression sedimentation), which is a widely recognized category in the standard classification of sedimentation types.
Spray drying — The claim that spray drying was first described in 1860 is not supported by established historical records; the earliest known description is Samuel Percy's 1872 patent.
Spray drying — The particle size range 'most applications falling between 100 and 200 µm' contradicts the LORE section's '100 to 300 µm' and is narrower than the typical cited range of 10–500 µm.
Steam distillation — The entry conflates steam distillation with hydrodistillation by stating it involves boiling water with other components, whereas steam distillation typically passes steam through the material.
Steam distillation — The entry incorrectly states that steam distillation works when the substance has a boiling point higher than water's; it actually works for immiscible substances with a lower boiling point at the mixture's total vapor pressure.
Suction filtration — The entry incorrectly states that the liquid passes into the vacuum flask; in standard suction filtration, the filtrate collects in the Büchner flask, not the vacuum flask.
Ultrafiltration — The entry states 'The process is not fundamentally different from microfiltration, as both rely on size exclusion or particle capture.' This is misleading; while both use size exclusion, ultrafiltration targets smaller solutes (10³–10⁶ Da) compared to microfil
Ultrafiltration — The entry says 'Concentration polarization occurs when rejected material accumulates at the membrane surface, reducing effective TMP and permeation rate; it is reversible by relieving TMP.' This is partially inaccurate: concentration polarization reduces the e
Ultrafast laser spectroscopy — Ultrafast laser spectroscopy typically studies processes on femtosecond to picosecond timescales; attosecond spectroscopy is a separate, more specialized technique.
Ultrafast laser spectroscopy — Laser-induced plasma from ultrafast pulses can produce femtosecond x-ray pulses, not exclusively picosecond.
Ultraviolet–visible spectroscopy — The claim that a 2nd order polynomial relationship is sometimes encountered for very large, complex molecules is not a standard or canonical description of deviations from the Beer–Lambert law; such deviations are typically attributed to chemical or instrument
Titration — The claim that the first true burette was invented in 1845 by French chemist Étienne-Ossian Henry is incorrect; the first true burette with a stopcock was invented by Karl Friedrich Mohr in 1855.
Titration — The claim that Gay-Lussac invented the terms 'pipette' and 'burette' in an 1824 paper is inaccurate; 'burette' was already in use earlier by Descroizilles, and the modern term 'pipette' was not coined by Gay-Lussac in that context.
