Phthalates Detection Pyrolysis  Gas Chromatography (PY-GC)

Phthalates Detection via Pyrolysis-Gas Chromatography (GC): RoHS 2.0 Compliant Solution
 

The RoHS 2.0-compliant Pyrolysis-Gas Chromatography (PY-GC) System offers a fast, accurate, and eco-friendly solution for detecting phthalate esters in various materials. Designed with optimized features for rapid analysis, it eliminates the need for solvents, complex preparation, and waste discharge—making it the preferred system for RoHS 2.0-compliant material testing in plastics, electronics, and polymers.

Key Benefits
 

• Rapid Analysis in Under 20 Minutes
  

Completes full phthalate detection in just 20 minutes, with no complex pretreatment steps required.
 

• Environmentally Friendly Operation
  

No wastewater or chemical solvents are used—ensuring the system complies with RoHS 2.0 environmental safety regulations and is exempt from environmental impact assessments (EIA).
 

• Simplified Sample Preparation
  

RoHS 2.0-compliant process involves only cutting and weighing the sample—eliminating chemical extraction or dilution steps.

• Precise Programmed Heating
  

Utilizes temperature-programmed pyrolysis for controlled and consistent thermal decomposition of the sample.
 

• Wide Sample Compatibility
  

Suitable for testing a variety of sample forms including solids, liquids, powders, foils, and colloids, meeting the diverse requirements of RoHS 2.0 analysis.
 

Primary Applications

• Targeted detection of RoHS 2.0-restricted phthalate esters (e.g., DEHP, DBP, BBP, DIBP)

• Commonly used for polymer screening, including plastics, cables, electronics, and household goods requiring RoHS 2.0 certification.
