Application

Morpholine has been used as a reference standard for the identification of the analyte in water by gas chromatography-mass spectrometry (GC-MS). It may be used as a reference standard for the determination of the analyte in fruit-based soft drinks, in natural waters and in vegetables by liquid chromatography-mass spectrometry (LC-MS) and in drugs by GC-MS.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
