A series of 16 polyarylates, with well-controlled and systematically varying chemistry, has been characterized by time-of-flight secondary ion mass spectrometry (TOF-SIMS). The polymers are structurally identical except for the incremental additions of C 2 H 4 units to the backbone and sidechain. Fr
## Abstract Time of flight secondary ion mass spectrometry (ToF‐SIMS) is an ideal technique for the analysis of adsorbed protein films because of its surface sensitivity and chemical specificity. In this study, we examined ToF‐SIMS with the multivariate calibration method partial least squares regr
Imaging time-of-flight secondary ion mass spectrometry (TOF-SIMS) of solid-phase peptide syntheses carried out by the Merrifield and Sheppard strategies is described. Mixtures of resin beads mixed at random from batch syntheses or obtained in combinatorial chemistry by the mix and split technique, w
