PRODUCT QUALITY
Quality defined.
Evidence explained.
Understand source qualification, trace impurities, sample testing and product acceptance for food-grade CO2 recovery. Review our sample-test summaries.
Food-grade confidence comes from a defined system of evidence.
Source qualification, a product specification, appropriate treatment and analytical verification are connected tasks. Neither a brochure purity percentage nor a single laboratory result replaces a plant-specific quality plan.
Selected laboratory sample results
| Sample / year | Report reference | CO₂, vol% | O₂, ppmv | Moisture basis | Sulfur basis |
|---|---|---|---|---|---|
| Hangzhou / 2022 | 2022I30-30-4147550001 | >99.999 | <0.1 | Atmospheric dew point −76.5°C | Total sulfur <0.1 ppmv |
| Heilongjiang / 2024 | 2024I30-30-5494961001 | >99.999 | 0.9 | Atmospheric dew point −68.3°C | Total sulfur <0.1 ppmv |
| Qiandao Lake / 2025 | 2025I30-30-5925311001 | >99.999 | 1.2 | Water 1.1 ppmv | Total sulfur excluding SO₂ <0.1 ppmv |
We reproduce selected SIMT sample results from our 2026 English corporate brochure. These results apply only to the submitted samples. Request the complete analytical reports for a qualification review. We retain the original moisture and sulfur reporting bases because they are not interchangeable.
What to agree before ordering
- Accepted source: process origin, composition envelope, trace impurities, sampling history and change notification.
- Product specification: required constituents and impurity limits, units, reference conditions and applicable destination-market requirements.
- Analytical plan: methods, sampling points, detection limits, calibration, frequency and responsibility for release.
- Off-spec handling: detection, isolation or diversion, investigation, corrective action and restart acceptance.
- Delivery quality: storage, loading, transport or vaporization controls to preserve the product.
Useful industry references
The International Society of Beverage Technologists publishes beverage-industry resources. The European Industrial Gases Association food and beverage resources provide further context. Obtain the applicable current documents and the customer’s specification; references alone do not certify a plant.
