A method to determine methylmethacrylate in air [PDF]

Acta Orthopaedica Scandinavica, 1988
To determine the air concentrations of methylmethacrylate monomer and thus obtain information about the safety in the operating theater, a methylmethacrylate Dräger tube was used in connection with a bellows pump. This method gives an instantly readable value correlated with more complicated gas chromatographic measurements.
