p**********m 发帖数: 472 | 1 Why I can see baseline seperation using ELSD, while very big tailing peak in
MS. And peaks between two detectors just cannot match.
what should I do next? help... |

These are two different detectors.
MS is more sensitive.

ELSD is a generic detector and MS only applies to ionizable compound. this
is like u r using pda at two different wave length and the profile could be
way different.

resolution lost came from.
try to match the tubing size and length for both detectors |

problem.
