Description
Le n-heptane est un solvant hydrocarbure aliphatique proposé sous la dénomination ROTISOLV® qualité HPLC avec une pureté minimale de 95 %. Il porte le numéro CAS 142-82-5 et la formule brute C₇H₁₆, avec une masse molaire de 100,20 g/mol. Sa densité se situe entre 0,68 et 0,69 g/cm³, sa plage d'ébullition est de 98,2 à 98,4 °C et son point d'éclair est de −4 °C. Ce solvant est répertorié pour une utilisation en chromatographie et est disponible auprès du fabricant Carl ROTH sous la gamme ROTISOLV® HPLC. Son intervalle d'ébullition étroit et sa pureté déclarée permettent une force solvante reproductible lors des séparations, de la préparation des échantillons et des procédures analytiques connexes où le n-heptane est spécifié comme phase organique ou diluant.
Cet article appartient à la catégorie Solvants qualité HPLC & LC-MS, dans Solvants. Voir aussi Solvants pour analyse (p.a.).

Questions about n-Heptane, ROTISOLV® min. 95 %, HPLC, 1 l, verre
What is this article?
n-Heptane, ROTISOLV® min. 95 %, HPLC, 1 l, verre is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Produits chimiques de laboratoire et industriels.
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 Solvents. The sub-category is HPLC & LC-MS grade solvents. The catalogue is Produits chimiques de laboratoire et industriels.
Shelves beside this one are Analytical grade solvents (p.a.), Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
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.
