AUTOMATIC BASE LINE CORRECTION SYSTEM FOR NMR SPECTRUM

摘要

PURPOSE:To decide a signal free area securely and to automatically perform a base line correction by utilizing NMR information during analysis. CONSTITUTION:It is judged that the interval between adjacent peaks is one peak group B when less than a value J or a signal free area when more than the value J. A point setting processing part 4 judges another signal free area C from the separated peak group B and sets several collection points A in the signal free area C. A base line correction processing part 5 generates a corrected base line based on the set collection points A to correct the base line of NMR spectrum data.
