Thin films derived by the deposition of charged microdroplets generated in ESI source a mass spectrometer act as highly concentrated reaction vessels which final products an ion-molecule can be isolated their precipitation onto solid surface under ambient conditions. In this study, Z-spray supplied to Q-TOF Ultima was used investigate d-fructose acid-catalyzed reactions stainless-steel target surface. High conversion ratios into 5-hydroxymethylfuraldehyde (5-HMF), 5-methoxymethylfuraldehyde (5-MMF), and difructrose anhydrides (DFAs) were obtained with HCl KHSO4 metal-free catalysts using synthetic conditions same bulk are not formed. Furthermore, outcome found sensitive catalyst solvent employed well parameters influencing thin film formation from
