Mixtures of porcine and bovine insulin analysed by fast atom bombardment mass spectrometry with selected ion monitoring.
Mixtures of bovine and porcine insulin have been analysed by fast atom bombardment mass spectrometry with selected ion monitoring of M + H ions at m/z 5733.9 (bovine) and 5778.0 (porcine). Porcine insulin could be detected in a mixture of 2% porcine and 98% bovine insulin and with bovine insulin as the minor component as little as 1% could be detected.
