EasyPyCal™ Py-GC-MS calibration standards
Synthetic polymer calibration standards for Pyrolysis Gas Chromatography Mass Spectrometry (Py-GC-MS). Select polymer type, diluent and polymer concentration between 1.0 µg/mg (0.1%) to 50 µg/mg (5.0%).
Production
Cryomilled, virgin microplastic fragments sieved through 300 mesh (<50 µm particles) ensuring consistent homogeneity across all available concentrations (down to 1.0 µg/mg). Microplastic fragments in dry, neat (powder) format are mixed with either SiO₂ or CaCO₃ diluent (calcined at 530°C), according to your requirements, to achieve the desired polymer concentration. The stock blends undergoes 14 hours of mechanical mixing with the addition of eight 304 stainless-steel beads ranging from Ø = 2.0 to 5.5 mm to ensure homogeneous particle distribution. The final blend undergoes also undergoes 14 hours of mechanial mixing with the addition of three Ø = 3.0 mm 316L stainless-steel beads.
Polymer type(s)
- Single-polymer blends: A single polymer in either SiO₂ or CaCO₃ diluent OR in neat powder format without diluent.
- Standard kit: 6 common polymers [PE, PP, PVC, PET, PS, PC] in SiO₂ or CaCO₃ diluent. All polymers in equivalent ratios.
- Advanced kit: 12 common polymers [PE, PP, PVC, PET, PS, PC, SBR, ABS, PMMA, PA6, PA6.6, PU (MDI-based, Estane® 58887*]. Choose either: (i) All polymers in CaCO₃ OR SiO₂ diluent, or (ii) 11 polymers in SiO₂ diluent with PU-MDI provided separately in CaCO₃ diluent. In both cases, polymers are present in equivalent ratios.
*The kit includes a well-characterized, commercially available MDI (Methylene diphenyl diisocyanate)-based thermoplastic polyurethane (Estane® 58887), representative of a broad class of aromatic PUs.
Important: In the 'basic and advanced polymer-blend kits', each polymer is supplied in equivalent concentrations and the selected concentration is indicative of the concentration of each individual polymer type. For example, if you select 1.0 µg/mg, you will receive 1.0 µg/mg of each polymer individually, rather than 1.0 µg/mg for the total polymer mixture.
Unit size
Single-polymer calibration standards are available in 0.5 g and 1.0 g aliquots at 149.95€ and 199.95€, respectively, regardless of polymer- and diluent composition. Standard- and advanced polymer kits are priced at 449.95€ and 549.95€ for 0.5 aliqouts, respectively, while 1.0 g aliqouts are priced at 549.95€ and 649.95€, respectively.
Please note that all samples include three 3.0 mm 316L stainless steel beads employed in the final mixing process. Do not attempt to remove the beads from the vial.

Certificate of Preparation
All samples are accompanied by a sample-specific Certificate of Preparation (COP), with full traceability of applied polymer content from stock mixtures to the specific sample. COPs are accessible via a weblink or QR code printed on each sample label.
