NOME STRUMENTO<\/strong><\/p>\n

Spettrometro portatile ALPHA-R Bruker<\/p>\n

 <\/p>\n

INFORMAZIONI GENERALI<\/strong><\/p>\n

La spettroscopia FT-IR in riflessione \u00e8 una spettroscopia vibrazionale ampiamente utilizzata nel campo della scienza per i beni culturali per l\u2019identificazione di materiali inorganici ed organici. La misura di specifici segnali relativi a gruppi funzionali molecolari permette la caratterizzazione chimica del materiale esaminato. La tecnica permette l’identificazione dei materiali costitutivi, degli eventuali materiali di ritocco e restauro, delle contaminazioni superficiali, delle alterazioni e dei prodotti di degrado.<\/p>\n

 <\/p>\n

DETTAGLI TECNICI<\/strong><\/p>\n

Lo spettrometro portatile ALPHA-R della Bruker lavora in riflessione raccogliendo la radiazione riflessa (con un layout ottico di circa (20\u00b0\/20\u00b0) da una superficie posta a 1 cm di distanza. La strumentazione \u00e8 dotata di una sorgente infrarossa Globar, di un interferometro di Michelson (RockSolid(TM)) e un detector DLaTGS. Lo spettrometro pesa 7 kg ed ha dimensioni 20x30x12 cm3<\/sup>. La testa di misura \u00e8 dotata di una telecamera che permette la visualizzazione del punto di analisi. Lo spettrometro pu\u00f2 essere movimentato verticalmente attraverso un soffietto manuale (collocato, per esempio, sopra un tavolo) fino ad un’altezza < 40 cm. In alternativa pu\u00f2 essere montato su un cavalletto dedicato e raggiungere un’altezza massima di circa 2 m (strumentazione posta orizzontalmente) o di 2.5 m (strumentazione posta verticalmente per analizzare soffitti e volte). L’avvicinamento alla superficie \u00e8 regolato da uno stage con controllo millimetrico. Il cavalletto \u00e8 anche dotato di ruote che rendono la movimentazione della strumentazione agile. Il minimo ingombro dello spettrometro e il suo ridotto peso ne permettono l’utilizzo anche su impalcature.<\/p>\n
