n-Heptane for gas chromatography ECD and FID SupraSolv®

Supplier: Merck

SupraSolv® ECD and FID is specially developed for gas chromatography in combination with ECD (Electron Capture Detetor) and FID (Flame Ionisation detector). SupraSolv® solvents offer the largest specified retention time range, a clear baseline and a minimal signal-to-noise ratio leading to reliable and reproducible analysis results.

Supplier: Merck

Suitable as solvent for the analysis of residual solvents of ICH classes 1, 2 and 3.

Supplier: ROBU GLASFILTER

These filters are suitable for degassing and filtration of solvents e.g. in chromatography.

Ces seringues C-line permettent de fixer l'aiguille au cylindre, ce qui élimine tout contact entre le solvant de l'échantillon et l'adhésif, réduisant ainsi le risque de contamination et de pics fantômes. Le polymère inerte de la pointe du piston favorise la compatibilité avec les solvants et une durée de vie allongée.

Un dégazage en ligne est plus efficace pour éliminer le gaz dissous dans les phases mobiles que la sonification ou le barbotage d'hélium. Jusqu'à cinq canaux de solvant peuvent être dégazés simultanément par un appareil. Le très faible volume de chaque canal en PTFE AF (480 μl) permet un équilibrage et un temps de démarrage rapides.
