Validation of passive samplers for monitoring of acetic and formic acid in museum environments

Abstract Acetic acid and formic are volatile pollutants leading to degradation of some heritage materials. They usually determined in museum environments with various types passive samplers. In this work, SKC UMEx 200 samplers, originally intended for sampling $$\hbox {NO}_{2}$$ NO 2 {SO}_{2}$$ SO , have been validated these organic acids. The rates, extraction efficiency, loss through reverse diffusion or during storage, capacity, detection limits were both For laboratory exposure, a known concentration acids was prepared flow-through reactor system at controlled temperature humidity, the samplers extracted, followed by analysis using ion chromatography. rates be 16.7 ml/min acetic 17.7 7-day exposure $${2.1}\,{\upmu }{\rm g/m}^3$$ 2.1 μ g / m 3 $${1.9}\,{\upmu }\hbox {g/m}^3$$ 1.9 g/m acid. method finally used air two case studies National Museum Slovenia, where concentrations range 2– $${54}\,{\upmu 54 determined.
