High Sensitivity HPLC analysis for the qualification and quantification of low levels of additives in polymeric materials
Increasingly stringent requirements imposed through regulation in areas such as materials for food contact and packaging are placing greater demands on analytical equipment. Levels of detection and quantification of < 10 bbp are becoming more common.
With Intertek's recent acquisition of the new HPLC systems from Agilent, utilising an extended path length cell for the Diode Array Detector, low levels of detection can be routinely achieved. The new system is a UHPLC instrument with an upper pressure limit of 600 bar, which together with the high speed 80 Hz diode array detector can make full use of the new sub-2 micron columns for rapid analysis with high sensitivity.
Low level additive analysis in polymers and plastics:
- Regulatory tests (such as specific migration) for food packaging
- Regulatory analysis, for example low levels of bisphenol A in baby bottles
- Plastics additives analysis and deformulation
