MALDI SpiralTOF™, Mass Spectrometry (MS), MS Application Notes |

Recently, Kendrick mass defect (KMD) plot analysis has been proposed as an effective data processing technique for SpiralTOF™ which allows for the structural characterization of complicated compounds1, 2. Here, a commercial acrylic adhesive containing cyanoacrylate was characterized using a SpiralTOF™ combined with KMD plot analysis.
