Fourier Transform Infrared Spectrometry (FTIR) is a very versatile and robust analytical technique increasingly used in archaeology for the characterization of artifacts and resolving issues such as mineralogy, sedimentology and diagenesis, and ancient pyrotechnology. The FTIR microscopy laboratory at BU is a unique facility that specializes on the in situ analysis of petrographic thin sections of sediments, soils, materials, and ecofacts.

 

 

Equipment

Spectrometer: Nicolet Nexus 470

FT-IR microscope: Spectra-Tech Continuμm equipped with MCTA and MCTB detectors and the following IR objectives: Spectra Tech Infinity Reflachromat 15X and Thermo Electron Infinity ATR with diamond crystal.

Sampling devices

  1. Micro sampling: Thermo-Fisher microcompression diamond cell
  2. ATR accessory: Thermo-Fisher Smart Orbit
  3. KBr Pellet preparation: Spectra-Tech Qwick Handi-Press

 

Surface preparation: Buehler Echomet Automet 250 polisher/grinder

 

 

Principal Archaeological Application

Identification of materials

Mineralogy, stratigraphy and site formation processes (e.g., diagenesis)

Reconstruction of prehistoric and ancient pyrotechnologies

State of preservation of bone and charcoal for dating and isotope analysis
