Sources and concentrations of aldehydes and ketones in indoor environments in the UK

Individual aldehydes and ketones can be separated, identified and quantitatively estimated by trapping the 2,4-dinitrophenylhydrazine (DNPH) derivatives and analysis by HPLC. Appropriate methods and detection limits are reported. Many sources of formaldehyde have been identified by this means and so...

Zusammenfassung:Individual aldehydes and ketones can be separated, identified and quantitatively estimated by trapping the 2,4-dinitrophenylhydrazine (DNPH) derivatives and analysis by HPLC. Appropriate methods and detection limits are reported. Many sources of formaldehyde have been identified by this means and some are found to emit other aldehydes and ketones. The application of this method to determine the concentration of these compounds in the atmospheres of buildings is described and the results compared with those obtained using chromotropic acid or MBTH.
