Beschrijving
Standaardmengsel van minerale oliën is een gebruiksklare kalibratiestandaard met 500 mg/l minerale olie en 500 mg/l diesel, aangeboden in een handige verpakking van 5 ml. Dit preparaat, dat wordt gekenmerkt door een dichtheid van 0,79 g/cm³, een vlampunt van −17 °C en een kookpunt van 56,05 °C, ondersteunt nauwkeurig analytisch werk in milieulaboratoria. Het is bijzonder geschikt voor water- en afvalwateranalyse voor de bepaling van de koolwaterstofindex volgens ISO 9377-2:2000 (H53-methode). Het mengsel van fabrikant Carl ROTH biedt een gedefinieerd gehalte aan minerale olie en diesel dat laboratoria helpt bij het vaststellen van betrouwbare referentiepunten bij het kwantificeren van koolwaterstoffen in waterige monsters. De gedocumenteerde fysische eigenschappen vergemakkelijken een gecontroleerde hantering in de routinematige laboratoriumpraktijk, terwijl het compacte volume van 5 ml geschikt is voor kalibratie, methodeverificatie en kwaliteitscontrole-workflows. Milieu-analisten kunnen deze standaard integreren in bestaande ISO 9377-2-protocollen om consistente metingen van de koolwaterstofindex te verkrijgen in diverse watermatrices en zo regelgevende monitoringprogramma's te ondersteunen.

Questions about Standaardmengsel van minerale oliën, 500 mg/l minerale olie, 500 mg/l diesel, 5 ml
What is this article?
Standaardmengsel van minerale oliën, 500 mg/l minerale olie, 500 mg/l diesel, 5 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, 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.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is Chromatography standards (GC, HPLC, pesticides). The catalogue is Chemicaliën.

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.
