Matrix-assisted laser desorption ionization-MS

The product was identihed by a number of spectroscopic methods. Dioxygen uptake was measured by spectrophotometric titration. MALDI-TOF-MS (matrix-assisted laser desorption/ionization-time of flight-mass spectrometry), an MS method particularly suited to determining molecular masses of biopolymers and synthetic materials with relative masses up to several hundred kilodaltons, determined that the product contained stoichiometric amounts of the heme starting material, the copper complex, and dioxygen in a 1 1 1 ratio.

Cryoscopy and ebulioscopy can be used for the measurement of Mn for polymers in a similar way to the application on smaller molecules, and the procedure is used mainly when Mn < 2 10. I LDI-MS (matrix-assisted laser desorption ionization-mass spectroscopy) allows the measurement of both Mn and M , as well as the molecular weight distribution, which indicates the variation of w, (weight fraction of the component i ), as a function of M,.
