Analysis of microscopic contamination in pharmaceutical products
Mid-infrared (MIR) microscopy is a useful chemical identification tool that is used to complement traditional light microscopy. Since first coupling an infrared (IR) spectrometer to a microscope, the technique has enjoyed widespread use in a variety of research and industrial applications including the analysis of pharmaceuticals.
In practice, the light microscope is used to locate the region of interest and then it is non-invasively and non-destructively sampled with infrared radiation to provide chemical identification of the desired microscopic area within the sample thus identifying the constituent distribution or any contaminants.

With Innovative Thinking,
We Are Changing Things For The Better
IR microscopy enables the industry to reduce manufacturing cycle times and product variability for shorter time-to-market and with fewer chances of product failures. You can utilize both standard mid-IR attenuated total reflection (ATR) imaging techniques and NIR direct reflectance to gain deeper insights into ingredient distribution in solid doses.
