Py-GC/MS calibration standards
Single-polymer calibration standards for Pyrolysis Gas Chromatography Mass Spectrometry (Py-GC/MS). Select polymer type, diluent and polymer concentration between 0.5 µg/mg (0.05%) to 50 µg/mg (5.0%).
Production
Cryomilled, general purpose microplastic fragments (not guaranteed additive-free) sieved through 1000 mesh (15 µm openings), yielding at least n = 500 particles per mg (at 0.5 µg/mg) and ensuring consistent homogeneity across typical 4 mg sample sizes. Microplastic fragments in dry, neat (powder) format are mixed with either SiO₂ or CaCO₃ diluent (muffled at 600°C), according to your requirements, to achieve the desired polymer concentration. The powder undergoes 24-hour mechanical mixing to ensure homogeneous particle distribution.
Sample content
- Single-polymer samples (in either SiO₂ or CaCO₃ diluent)
- Standard kit: 6 common polymers [LDPE, HDPE, PP, PVC, PET, PS, PC] (in SiO₂ diluent only). All polymers in equivalent ratios.
- Advanced kit: 12 common polymers [+ ABS, PMMA, PA6, PA6.6, PU {thermoset}, TPU {thermoplastic}] (Mostly in SiO₂ and polyurethanes in individual CaCO₃ diluent). All polymers in equivalent ratios.
Please note that in polymer kits, each polymer is provided at the same concentration. For example, if you select 1 µg/mg, you will receive 1 µg/mg of each individual polymer, not 1 µg/mg for the total polymer mixture.
Format
Single-polymer calibration standards are available in 0.5 g and 1.0 g aliquots at 149.95€ and 249.95€, 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.
▶ To enable baseline correction pure diluent controls accompany all samples
For best performance, we recommend placing a small plug of quartz wool (not included) above the sample in the pyrolysis cup. Alternatively, the sample can be wetted with a drop of solvent to prevent particle fly-off.
