title: Raw Data: Corrosion of Steel Strings of Historical Musical Instruments Triggered by the Emissions of Degrading Cellulose Nitrate

description: Raw Data of SPME-GS-MS, Headspace GC-MS, XRD, XPS, Raman, IR-spectroscopy and SEM-EDS  

Three historic musical instruments from the collection of the Norwegian Museum of Music, Ringve and Rockheim (The Museums of Southern Trøndelag) in Trondheim, Norway were investigated. Corrosion on steel strings mounted close to parts of degrading cellulose nitrate (CN) was observed. Samples from the strings, the corrosion products, the CN and the CN's emissions were analysed. 

The following musical instruments were involved:1. Banjo mandolin (RMT 721), produced in Germany around 19502. Bass-sitar (RMT 66/23), produced in India around 19503. Guitar (ROCK2725), produced in Italy in 1967

The raw-data published in this repository were generated by analysis of the CN's emissions (Em) by solid phase micro extraction (SPME) gas chromatography-mass spectrometry (GC-MS), the CN samples (CN) by Headspace GC-MS, the corrosion product on strings (Corr) by  X-ray diffraction (XRD) and  X-ray photoelectron spectroscopy (XPS), IR-spectroscopy (IR) and Raman spectroscopy (Raman).
