Beschrijving
Potassium hydrogen phthalate-oplossing is een kant-en-klaar laboratoriumreagens gestandaardiseerd op 200 mg CSB/l (0.17 g KHP/l) voor analytisch werk. De opgeloste stof komt overeen met CAS-nummer 877-24-7, EG nr. 212-889-4 en de empirische formule C₈H₅KO₄, met een molaire massa van 204.23 g/mol. Het waterige preparaat heeft een dichtheid van 1.005 g/cm³ en een kookpunt van ongeveer 100 °C, en is geassocieerd met UN-nummer 3264. Deze oplossing van fabrikant Carl ROTH is bedoeld voor chemische laboratoria die een consistente op KHP gebaseerde standaard nodig hebben zonder verdere bereidingsstappen. Duidelijke concentratie-etikettering samen met gedocumenteerde molaire massa en dichtheidsgegevens helpt traceerbare workflows te handhaven in wateranalyse en gerelateerde natchemische methoden waarbij op CSB betrekking hebbende standaarden worden toegepast.

Questions about Potassium hydrogen phthalate-oplossing, 200 mg CSB/l (0.17 g KHP/l), 250 ml
What is this article?
Potassium hydrogen phthalate-oplossing, 200 mg CSB/l (0.17 g KHP/l), 250 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatografiestandaarden (GC, HPLC, pesticiden), inside Analytische standaarden & referentiematerialen, in Chemicaliën.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.

What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
