MEASUREMENT EXAMPLES

ATR-FTIR

ATR-FTIR is the dominant FTIR method for analysis of solids and liquids as it requires little to no sample preparation and is non-destructive. With ATR-FTIR an Internal Reflective Element (IRE) is used as the ATR crystal that the beam of radiation is directed into. 

Figure 1: ATR-FTIR spectrum of Human serum.

A range of materials are available for the ATR crystal, and the decision of which one to pick is based on application area. ZnSe is suitable for routine analysis, however, harder samples can cause the crystal to crack or shatter and strongly acidic or basic samples can cause toxic fumes. Germanium is suited to samples with a high refractive index and surface studies due to its smaller depth of penetration. The gold standard material for ATR crystals is diamond; it’s virtually indestructible, whilst offering high thermal conductivity for heated ATR-FTIR experiments. 

Transmission FTIR spectroscopy is the most traditional method to analyse samples. Incident infrared light passes through the sample, and the amount which transmits through is measured producing an FTIR spectrum in %Transmission.

Transmission FTIR can be used for liquids, solids, and essential for gas phase measurements. Sample preparation is typically required for transmission measurements; solid samples may require dispersion in KBr and pressed into pellets, and IR transparent windows, such as CaF2, are required for measuring liquids.  

The IA30 can host numerous other sampling accessories, offering a full suite of FTIR techniques. For example, specular reflectance accessories are particularly useful for analysing thin films. Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) is excellent for collecting IR spectra from strongly absorbing samples with rough surfaces, such as powders.

Accessories are designed for specific end user needs, for example heated ATRs can be offered to track phase transitions in samples. Liquid transmission cells are offered to allow for fast and easy application of the sample, and for cleaning between samples with huge benefits to sample throughput.
