TL;DR: In this paper, the laser desorption (LD) was used as an ionization method for bile acid compounds and the LD mass spectra contained abundant positive and negative quasimolecular ions.
Abstract: Bile acids are important in the diagnosis of certain diseases. Their mass spectra are usually obtained by electron impact or chemical ionization and are dominated by fragment ions. We have investigated laser desorption (LD) as an ionization method for these compounds. The LD mass spectra contain abundant positive and negative quasimolecular ions. Bile acid salts can be successfully analyzed. In addition, the results help to elucidate details of the LD process.
