Description
Acetonitrile with 0.1 % acetic acid is a ROTISOLV® LC-MS-Grade solvent preparation with a minimum purity of 99,9 %, formulated for chromatographic and mass-spectrometric applications. Based on acetonitrile (empirical formula C₂H₃N), it has a molar mass of 41,05 g/mol and a density of 0,79 g/cm³. Key physical data include a boiling point of 81,65 °C and a flash point of 12,8 °C, with UN number 1648. The pre-mixed acetic acid modifier supports stable acidic mobile phases for LC-MS, helping to control retention and enhance analyte response without separate acid addition. Supplied in a 2,5 l pack, the product suits routine eluent preparation in analytical laboratories. This solvent blend from manufacturer Carl ROTH belongs to the ROTISOLV® line for solvents with eluent additives and is positioned for reliable performance in liquid chromatography coupled to mass spectrometry.

Questions about Acetonitrile with 0.1 % Acetic acid, ROTISOLV® min. 99,9 %, LC-MS-Grade, 2.5 l
What is this article?
Acetonitrile with 0.1 % Acetic acid, ROTISOLV® min. 99,9 %, LC-MS-Grade, 2.5 l is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
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 Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
