Due to the lack of access to my university's laboratories and equipment I'm exploring the efficiency of FTIR in the characterisation of bone samples from reviewing literature as opposed to practical experimentation.
Most of the advantages FTIR over other techniques have been stated to be:
- its speed and ease of analysis
- the low cost of the instrument as compared to other (Raman spec, etc)
- the availability of spectral databases
- its non-destructive character
I am slightly wary of bringing up FTIR in discussions about non-destructive techniques since it requires the preparation of pellets from the sample together with KBr. Even with the ATR attachment, FTIR appears to require the preparation of hard solids into powder for proper crystal penetration - thus, not entirely non-destructive.
I realise the definition of the term is not clear-cut in analytical sciences but do you have any experiences with FTIR-ATR and the analysis of bones or teeth? How have you prepared your samples, and have you found any benefits for using this technique as compared to other?
Dear.,
Using FTIR-DRIFT is different from ATR MIR spectra. using FTIR, sample's powder is used but in ATR may suspension is used.
The conventional methods of analysis are laborious, slow, costly, harming environment, consuming lot of chemicals, and need more samples preparation.
Compared to conventional methods, diffuse reflectance spectroscopy using Fourier Transform Infra Red in the range of Mid Infra-Red spectra (2.5 to 16 micrometer) is much easier, rapid, not need much sample preparation, no need for chemicals and this method is environment-friendly.
