Contamination

Contaminant identification is one of the largest Raman application areas. Almost all manufacturing sites around the world are at threat from contamination, which can cause costly production stoppages. This also extends to environmental and regulatory monitoring of materials and pollutants.

Examples of contaminants include:

  • particulates on semiconductor wafers
  • corrosion products on metal items
  • oils and cutting fluids on manufactured items
  • foreign matter in pharmaceutical ingredients
  • polymer particles (such as microbeads) within large water sites

Raman analysis of contaminants

Raman spectroscopy is a great technique to identify the contamination, and help determine its source. Renishaw Raman systems get you the best possible data, helping you identify contaminants rapidly and easily. They offer:

  • high sensitivity, with sub-micrometre spatial resolution – analyse tiny traces of material and thin films
  • Raman spectral databases – so you can quickly identify contaminants 
  • multiple lasers, from the UV to IR – have the flexibility to analyse a wide range of samples
  • non-destructive and non-contacting analysis – preserve the evidence of contamination
  • options for locating, analysing and automating measurements on particles of different sizes

We understand the problem

No matter how careful the manufacturing process, things change and contamination can occur.

Renishaw is at the forefront of advanced manufacturing and is renowned for the high quality of its products. Our engineers use inVia Reflex confocal Raman microscopes as part of Renishaw's quality control processes; we understand the challenges of contamination.
