Miracle package offers two user levels making it suitable to a wide range of applications. Standard user mode is optimal for analysis and teaching labs where routine experiments are carried out. Advanced user mode unlocks instrument configuration options and complex analysis functions, suitable for R&D and the most demanding applications.

Data analysis in Miracle is highly flexible: it is possible to undo or rearrange processing steps, so you can access the raw data and fine-tune your analysis. The software allows you to reapply apodization with a different function, for better comparison with other spectra.

MEASUREMENT EXAMPLES

ATR-FTIR
Transmission 
FT-PL
More Sampling Accessories 
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 

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.  

FT-PL

The IR5 can also be configured to measure photoluminescence (PL) spectra in the mid-infrared region. For this measurement an excitation laser is required, which is focussed onto the sample. The sample’s PL emission is then optically guided into the interferometer and through to the detector. This technique is mainly used to look at MIR photoluminescence of rare-earths and semiconductors.

FT-PL spectrometers, employing interferometers and non-dispersive technology, offer improved sensitivity and more accurate signal representation for mid-infrared PL studies compared to traditional dispersive instruments. By capturing the full spectrum simultaneously, they reduce noise and maintain uniform spectral resolution. 

More Sampling Accessories 

The IR5 can host numerous other sampling accessories offering a full suite of FTIR techniques. For example, specular reflectance accessories which 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.
