Genevac has over 20 year’s experience of supplying evaporators for removal of solvents from oil, fat and fuel samples.
Oils, fats and fuels are normally isolated from natural sources using extraction or separation techniques that present the final sample in a solution of organic solvent. Before analysis such samples must be dried or concentrated.
Whether extracting and recovering additives, evaluating lipid content of foods, characterizing reclaimed cooking oils before reprocessing / conversion to biofuels, or investigating drillling test samples - oils, fuels and fats can often prove difficult to dry without using very high temperatures which may lead to loss of the more volatile fractions within the sample.
For many such applications, researchers have found that the Genevac EZ-2 and Rocket Evaporators have significantly enhanced recovery and results.
When working with larger solvent volumes, additional benefit is gained by way of productivity savings when using Genevac evaporators with SampleGenie technology which enables large volumes to be concentrated or dried directly into a small vial.
Many oil and fat analyses require use of potentially explosive solvents, such as di-ethyl ether.
These can be safely evaporated in Genevac systems fitted with the Inert Gas Purge option, which removed all the air from the system before use, replacing it with inert gas and thereby preventing incident.
