Total Petroleum Hydrocarbons (TPH)

Petroleum contamination is a significant concern for both the environment and human health. Our ‘TPH’ product package allows thorough characterisation of both aliphatic and aromatic components in a single run, without the need for sample fractionation.

The challenge

  • Samples are complex, and require the aliphatic and aromatic components to be separated and quantitated.

  • Existing workflows require time-consuming and labour-intensive SPE sample fractionation.

  • Current multi-step sample preparation approaches use costly consumables, and also increase the risk of error.

  • Multiple platforms (GC–MS and GC–FID) are required to characterise both volatile petroleum hydrocarbons (VPH) and extractable petroleum hydrocarbons (EPH).
     
  • Previous approaches require multiple analyses, with complex chromatograms making integration difficult and subjective.


Thorough characterisation of aliphatic and aromatic components in a single run is achieved using our ‘TPH’ product package, which eliminates the inconvenience of SPE workflows.

The solution

  • INSIGHT® GC× GC flow modulation provides enhanced separation with repeatable results across lengthy clinical trials, even for the most volatile species.
     
  • ChromSpace® software provides simple group-type analysis and reporting of the TPH-CWG bands.

The benefits

  • Easier operation: Labour-intensive, multi-step SPE sample fractionation is eliminated, and GC–MS is no longer required for VPH methods.
      
  • Reduced cost: Fewer consumables are needed, and solvent waste is reduced.
     
  • Faster reporting: Fully automated workflows allow real-time data processing, with all analytes reported in a single run.
     
  • Doubled productivity: Dual-channel GC×GC allows two samples to be run at once.
     
  • Increased reliability: Minimal sample preparation minimises the risk of error, while automated data-processing avoids operator subjectivity.
