HVAC & geothermal
Turn operating temperatures, formulation data, and service history into a more useful heat-transfer-fluid specification.
Explore the collection →Guides / evidence / purchasingWater & wastewater treatment
Connect source-water evidence, treatment objectives, and residuals management before specifying a chemical.
Explore the collection →Guides / evidence / purchasingAerospace materials & cleanliness
Separate chemical purity, hardware cleanliness, and system compatibility—and ask for the evidence each decision requires.
Explore the collection →Guides / evidence / purchasingMetal finishing & surface treatment
Write the operation, the concentration basis and the contaminant limits into the purchase request—before the drum reaches the bath.
Explore the collection →Guides / evidence / purchasingLaboratory & pharmaceutical research
A grade is a specification a material was tested against—not permission to use it. Write the method, the attribute limits and the lot documents into the request.
Explore the collection →Guides / evidence / purchasingPaper & pulp
Membrane, papermaker’s, technical: a mill buys most of its chemistry on trade words. Write the substance, the concentration basis and the attribute limits into the request instead.
Explore the collection →Guides / evidence / purchasingOil & gas
K-1, twenty degrees Baumé, inhibited: a field buys fuel, acid and fluoride chemistry on trade words. Each of those names a document, a hydrometer reading or a formulation. None of them is a set of attribute limits.
Explore the collection →Guides / evidence / purchasingFood & beverage processing
Food grade, FCC, GRAS, HT1: a plant buys ingredients and utility chemistry on words that sound like a status. Each one points at a document, an edition, a use condition or a registration. None of them is a property of the drum.
Explore the collection →Guides / evidence / purchasingGovernment & municipal
NSF/ANSI 60, “or equal,” 23 percent, a qualified product: a public buyer writes chemistry into a solicitation that bidders, auditors and a reviewing authority will hold them to. Each of those words names a rule, a listing, a basis or a named product. None of them is enforceable until the document says which.

Guides explain applications and purchasing questions. Product specifications and lot documents remain with the product record. Sources and limitations appear alongside the technical discussion so you can assess what the evidence supports.
