Webwell as selective enrichment. These expressions indicate that selectivity is regarded as something that can be graded. Methods have often been described in qualitative terms, such as having good selectivity or even high, excellent, or extreme selectivity. This qualitative use of the term has been discouraged. WebJul 3, 2015 · Detector classification according to selectivity. A universal detector is defined as the one which ‘can respond to every component in the column effluent except the mobile phase’ 2.In contrast, selective detectors are defined as ‘detectors which respond to a related group of sample components in the column effluent’. Finally, specific detectors are …
