Abstract: The present invention concerns an apparatus and method for testing materials. More particularly, but not exclusively, this invention concerns an apparatus and method for testing materials which have a useable shelf-life. The invention also concerns an apparatus and method for testing materials which have a useable shelf-life dependent on the chemical degradation of the material. The invention provides a method of obtaining an indication of the lifespan of a chemically reactive material. The method comprises taking an infrared (IR) spectroscopic measurement (26) of the material. The measurement results are compared (28) to a database of previously obtained measurement results. Depending on the comparison (28) of the measurement result to the database of previously obtained measurement results, an indication (30) of a measure of the lifespan of the chemically reactive material is determined and provided. An infrared spectrometer (32) and a method of calibrating an infrared spectrometer is also provided.
