About the Company: 

Trojan Technologies is the world leader in advanced ultraviolet (UV) fluid treatment technology.

Project Description:

Ultraviolet irradiation is effective for inactivating bacteria and viruses. However, in complex matrices it has the possibility of initiating unwanted reactions resulting in undesirable byproducts. This project will analyze UV-treated liquids using LCMS/MS, GC/MS, HPLC, and UV-Vis to identify and quantify byproducts in liquid foods.

Research Objectives:​

  • Identify and quantify byproducts in UV-irradiated fluids
  • Investigate methods to mitigate or enhance photochemistry


  • Compare chromatograms of control and irradiated samples. Identify compounds
  • Find and develop analytical methods for LCMS/MS or GCMS analysis and quantification

Expertise and Skills Needed:

  • LCMS method development
  • Sample preparation, e.g. SPME, SPE, derivitization
  • Documentation, LC and MS troubleshooting, lab inventory, waste management, etc.
