Description
Organic Solvents Standard ROTI®Star est un étalon d'étalonnage à trois composants dissous dans ethanol pour la chromatographie ionique et les applications d'analyse environnementale. Les concentrations des composants en mg/l sont 3-pentanol (CAS 584-02-1) à 400 mg/l, 2-butanone (CAS 78-93-3) à 20000 mg/l et 2-propanol (CAS 67-63-0) à 20000 mg/l. Ces teneurs documentées en solvants organiques aident les laboratoires pour l'étalonnage des instruments, le développement de méthodes et les contrôles qualité dans les flux de travail de chromatographie. La préparation fait partie de la gamme ROTI®Star du fabricant Carl ROTH et est destinée à un usage professionnel lorsque des étalons multi-analytes dans une matrice éthanolique sont requis. Des valeurs de concentration claires pour chaque composant soutiennent des schémas de dilution cohérents et une comparaison fiable des résultats analytiques entre les séries IC successives et les techniques associées.

Questions about Étalons IC, 2 ml, 3 composants dans Ethanol, Concentration en mg/l
What is this article?
Étalons IC, 2 ml, 3 composants dans Ethanol, Concentration en mg/l is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Solvants de qualité HPLC & LC-MS, inside Solvants, in Produits chimiques.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvants. The sub-category is Solvants de qualité HPLC & LC-MS. The catalogue is Produits chimiques.
Shelves beside this one are Solvants de qualité analytique (p.a.), Solvants secs & deutérés (NMR, synthèse), Solvants de qualité technique & synthèse and Solvants verts & alternatifs.
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.
