Autor: Mirkka Koivusalo, Perttu Haimi, Liisa Heikinheimo, Risto Kostiainen, Pentti Somerharju

Publikováno v: Journal of Lipid Research, Vol 42, Iss 4, Pp 663-672 (2001)

Electrospray ionization-mass spectrometry (ESI-MS) is a very promising tool for the analysis of phospholipid compositions, but is hampered by the fact that not all molecular species are detected with equal efficiency. We studied this and other issues
