Preservation at BnF : laboratory

Aux activités de conservation curative traditionnelle et à la reliure (qui a été intensifiée), sont ainsi venues s’ajouter des activités et des approches nouvelles :

  • Prévention/Préservation,
  • Formation /Sensibilisation,
  • Traitements de masse/Numérisation,
  • Recherche et veille technologique
La gestion des bâtiments et de leur climat (température, hygrométrie), la formation des personnels, la mise en sécurité des collections contribuent, en complémentarité avec le traitement direct des collections, à en assurer les meilleures conditions de conservation. Le développement de ces activités a conduit à la définition d’une véritable politique de conservation et de préservation.

Laboratory equipment

The laboratory has a full range of scientific equipment for carrying out the necessary research and analysis.

Fourier transform infrared (FTIR) spectrometer

Fourier transform infrared (FTIR) spectrometer

Fourier transform infrared (FTIR) spectrometer

This simple-to-use, non-destructive technique can be used to obtain information about the molecular structures and chemical relationships found in organic and inorganic materials.

It is used to identify plastic packaging materials, adhesives used in stickers, varnish, glue, textiles, etc.

Equipment used:
Perkin Elmer Spectrum 2000 system with microscope and diamond ATR

Chromatography

Equipment for liquid phase chromatography

Equipment for liquid phase chromatography

Chromatography is an analytical technique for separating the various constituents of a mixture. It can be used to both identify and quantify components such as binding agents, colorants, plasticizers, volatile compounds, tannins, etc.

Chromatographical methods may be categorized according to the physical nature of phases (mobile and stationary). The most common methods are gas phase chromatography (GPC) and high-performance liquid chromatography (HPLC).

Liquid phase chromatography (HPLC)

This technique is used, for example, to analyze the degree of degradation of cellulose in paper (to measure the impact of paper treatments).

Equipment used:
Beckman system with a diode-array visible ultraviolet (UV-vis) radiation detector and a refractometric detector

Gas phase chromatography

This highly sensitive separation technique is used to work on very small samples and analyze complex mixtures of ancient and modern organic materials:
  • characterizing animal glue used for restoration
  • identifying efflorescences taken from leather bindings 
  • identifying volatile compounds emitted by materials 
  • identifying plastics (by pyrolysis)

Equipment used:

Finnigan GCQ system comprising a chromatograph

Finnigan GCQ system comprising a chromatograph and an ion trap mass spectrometer (GPC/MS) combined with a Pyroprobe CDS1000 pyrolyser

Perkin Elmer Autosystem comprising a chromatograph

Perkin Elmer Autosystem comprising a chromatograph and a thermal desorber 

Physical measurement devices

Testing machines for characterizing the principal mechanical properties of standardized test tubes.

Equipment used:

Tear strength tester

Tear strength tester

Dynamometer
