Guided Wave’s use of NIR and UV/Vis technologies and spectroscopic techniques provides an effective and efficient means of monitoring and controlling production in real-time … either in continuous or batch processes. Having the ability to obtain near-instantaneous results is an essential tool for improving quality control and fine-tuning formulations. Monitoring in real-time eliminates the guesswork about when formulations are correct and within quality control limits.

  • Provides continuous, accurate, and precise real-time, in-situ information to constantly monitor input stream purity and final product quality
  • Allows simultaneous measurement of multiple parameters that are key to manufacturing a safe and precisely formulated product
  • Reduces overall process sample-point cost through the use of Guided Wave multi-channel analyzers
  • Helps increase efficiency of the production process through real-time information
  • Customized process analytical systems tuned to your specifications

In Pharma, constantly monitoring final product quality is essential. The ability to simultaneous measure and monitor multiple parameters simultaneously during production, even at multiple sampling points, helps achieve product quality and process efficiency.

Processes used to manufacture semiconductors require precise quality control and the use of hazardous, highly corrosive chemicals. One key element of being able to make in-situ, real-time measurements of chemical component concentrations is the monitoring point. Guided Wave designs and manufactures sample interfaces in a variety of materials and configurations that withstand these harsh conditions. Coupled with a Guided Wave analyzer platform via fiber optic cables, this optically-matched and optimized analyzer system:
  • Provides continuous, accurate, and precise real-time, in-situ information to monitor and help control bath concentrations
  • Helps the manufacturer increase the efficiency of the production process through real-time information
  • Reduces, or eliminates, the need to remove and dispose of chemical samples
  • Improves operator safety by reducing exposure to hazardous chemicals by taking such periodic samples
  • Preserves the integrity of the process chemical composition by employing non-metallic and chemically inert sample interfaces at the monitoring point

Hydrogen peroxide (H2O2) is widely used for sterilization in a variety of industries as an environmentally friendly alternative to previous sterilizing chemicals. The main difficulty with this technique is the need to measure concentrations of H2O2 in a sterilized environment, in the presence of water vapor (H2O) in a vacuum and ambient conditions. Guided Wave provides a turn-key NIR spectroscopic-based analyzer system to measure gaseous H2O2 and H2O vapor concentrations in real-time without the need to sample, which could introduce contamination to the sterilizing environment. The monitoring probe is placed inside the sterilization environment and connects vis fiber optic cables to the remote HPV analyzer:
  • H2O2 vapor … 0.1 – 50 mg/L (72 - 35,600 ppm V/V), with ± 0.1 mg/L error
  • H2O vapor … 1.0 mg/L to condensation (>1345 ppm), with ± 1.0 mg/L error
