hRf Explanation: I am 74.5% sure I have seen it as such - the name of a test, an international acronym you should leave as is. Google was no help, however. |

peer agreement (net): +1hRf Explanation: hRf value Retention factor * 100 Retention factor A variable used to characterise the position of a substance in a chromatogram. Definition: distance between start line and substance zone divided by the distance between the start line and the mobile phase front. Rf values lie between 0 and 1. They depend on the chromatographic conditions, matrix substances in the samples and are only applicable to chromatograms that have been developed once. Rf x 100 yields the hRf value.
