ABSTRACT:

rccc-2,8,14,20-Tetra-n-octyl-5,11,17,23-tetrahydroxyresorc[4]arene has the property to form cluster ions in both positive- and negative-ion mode with good intensity without the addition of any modifiers such as cesium. These cluster ions may be used for the calibration of electrospray mass spectrometers in the mass range up to m/z 6000.

Keywords: ESI, mass spectrometry, calibration, high mass, calixarene, resorc[4]arene
