| Abstrakt: | SUMMARIES. To establish suitable quality control mechanisms by which mass deacidification systems can be evaluated and compared. General guidelines are necessary by which customized programmes can be formulated. A newly developed analytical technique provides an accurate tool to evaluate mass deacidification techniques which makes the control of the deacidification efficacy possible. Five commercial processes have been investigated between 2002-2003 and the results achieved are presented. In addition selection crtieria for heterogeneous collections and working logistics are of decisive importance. Basic models are given according to which institutions may develop their treatment and working structure. CONCLUSIONS. Sampling and analysis of volatile compounds formed in the course of paper degradation permitted the identification of marker substances indicative for acid hydrolysis and oxidative degradation of groundwood paper. The analytical procedure could successfully be applied to evaluate and monitor the efficacy of five commercially available mass deacidification processes. Mass deacidification will always require a significant amount of organizational support within the contracting institution. Acceptable results can only be achieved through the establishment of intensive co-operation between specialists responsible for the collections to be treated and the personnel of the deacidification providers. However, standardized and clearly explained quality evaluation reports for all deacidification processes are of decisive importance. Unfortunately, a universal model for selection criteria of collections materials, or a universal model for the workflow that could be used by institutions involved, cannot be established. Nevertheless, it is possible to present basic models according to which institutions may customize their treatment and working structure. |
