FTIR-Spectrometer; Alpha II, Bruker
- General description: Structural and chemical analysis (FTIR in reflection mode) of mostly organic materials and some inorganic pigments, filler materials and degradation products.
- Application aim: Molecular analysis of organic and inorganic materials, in particular pigments and dyes, binders, fillers and sizing agents.
- Mobility: portable; 1 box of 7.5 kg + tripod
- Equipment specifications:
- Spectral resolution: 2 cm-1
- Spectral range: 400–4000 cm-1
- Detector: High resolution DTGS
- IR source: Air cooled, 12V, 20W
- Module: contactless, non destructive reflection
- Integrated video camera for the visualisation of exact measuring spot
- equipment specifics: gold reference cap
- sample required: no; contact required: yes;
- interaction spot dimensions: Sample cap with variable sample spot diameter starting from 5 mm; sampling spot distance from the spectrometer of 15 mm
- limitations: surface analysis; instrument on table or tripod; if the contact is unstable, it results in noisy spectra.
- Application requirements: T=5–35°C; RH < 80%, power supply 48 W
- Sample required: no
- Contact required: yes
- Set up time: 20 min excluding warm-up, additional 30–40 min for warm-up and quality tests
- Average time for measuring: depending on the number of scans/measure: average 2 minutes; minimum 16 scans are needed
- Average time for processing: depends on the complexity of the spectra (between few minutes to one hour)
- Software package: OPUS 8.8.4
- Output: Data Size and Data Format
- Evaluation program: Omnic or Origin
