PLM microscope

What is PLM Analysis why is it important?

Polarized Light Microscopy (PLM) is a critical analytical tool in the characterization of drug powders, vital for understanding their microstructural properties and behaviour.

What is PLM Analysis used for?

PLM is particularly adept at providing insights into:

  • Particle Morphology

  • Crystallinity and Polymorphism

  • Flow Properties

  • Blend Uniformity

  • Contaminant Detection

Frequently Asked Questions

Traditional light microscopes utilize non-polarized white light, which is visible to the human eye, whereas polarized light microscopy employs polarizing filters to utilize polarized light.

 

Polarized light microscopy (PLM) is utilized to ascertain the crystallinity of a sample. An amorphous sample will not display birefringence when observed under polarized light, whereas a crystalline sample will exhibit this property.

This technique enables the determination of whether a crystal is optically uniaxial or biaxial and whether it exhibits optical positivity or negativity.
