What Is ASTM D8133 Low Level Phthalates PVC Solvent Extraction?
ASTM D8133 provides a standard test method for determining low-level phthalate plasticizers in PVC plastics using solvent extraction followed by gas chromatography-mass spectrometry (GC-MS). The method quantifies regulated phthalates, including DEHP, DBP, BBP, DINP, DIDP, and DNOP, at concentrations relevant to RoHS, REACH SVHC, and toy safety regulations.
Solvent extraction per ASTM D8133 is applicable to a broad range of PVC concentrations and provides well-validated, globally accepted analytical data for compliance demonstration in international markets.

- Applicable to both high- and low-concentration PVC samples
- Excellent sensitivity and selectivity via GC-MS
- Well-validated method with extensive interlaboratory data
- Provides defensible compliance data for export markets
Our ASTM D8133 Testing Procedure
Sample Preparation
PVC specimens are cut or ground into small pieces; a precisely weighed sample (~1 g) is dissolved or extracted in THF or the specified solvent at ambient or elevated temperature.
1Extract Preparation
The extract is filtered, diluted to a defined volume, and spiked with internal standards before GC-MS injection.
2GC-MS Analysis
Phthalate compounds are separated by GC and identified and quantified by mass spectrometry in full scan or SIM mode against certified external and internal calibration standards.
3Quantification & Reporting
Phthalate concentrations (wt%) are calculated; results are compared to regulatory limits and a compliance report with pass/fail determination is issued.

ASTM D8133 Low Level Phthalates PVC Solvent Extraction FAQs
ASTM D8133 dissolves the PVC matrix in THF to extract phthalates — suitable for a wide concentration range. ASTM D7823 uses thermal desorption, which is faster and solvent-free but may have limitations at very high phthalate concentrations. D8133 is more universally applicable and widely specified in global regulations.
Yes. GC-MS with selective ion monitoring can differentiate between structural isomers of phthalates (e.g., DINP and DIDP from DEHP) based on retention time and mass spectral fragmentation patterns, enabling accurate identification and quantification of each regulated phthalate.
XRF provides rapid elemental screening but cannot speciate or quantify individual phthalate compounds. XRF may be used for initial screening, but GC-MS (ASTM D8133 or D7823) is required for definitive quantification and regulatory compliance confirmation.
Approximately 1–5 g of sample is required for the extraction, plus additional material for replicate analyses. For composite articles with multiple PVC components, each component must be tested separately per applicable regulatory requirements.
Yes. ASTM D8133 is recognized as a valid analytical method for phthalate determination in polymeric materials under EU REACH (SVHC), EU RoHS 2, and similar national regulations. It is widely accepted in third-party laboratory compliance test reports.
