A non-destructive dry swabbing sampling method was developed and validated to characterize surface exudates on heritage poly(vinyl chloride) (PVC) objects that show evidence of degradation. Coupled with non-proximate desorption photoionization high-resolution mass spectrometry (NPDPI-MS), this appro ...

The predominance of diffusion-evaporation of plasticizers in heritage collections is investigated and an analytical method of studying surface exudates based on dry swabbing is introduced for an in-situ museum survey. Most plasticized heritage PVC objects exhibit no visible surface exudates, indicat ...
