Not all N2O is created equal. While many cream charger suppliers advertise “99.995% purity,” very few can actually prove it. And for buyers, especially those selling in regulated or premium markets, gas purity can make or break your reputation.

At nitronovae, we don’t just promise quality—we provide real, verifiable COA (Certificate of Analysis) for each production batch. In this article, I’ll show you how to interpret these documents and avoid falling for fake or meaningless purity claims.

1. What Does “99.995% Pure N2O” Actually Mean?

It means that out of one million gas particles, no more than 5 parts can be impurities.

✅ Good COA = shows exact ppm (parts per million) of:

• Oxygen (O₂)
• Nitrogen (N₂)
• Carbon monoxide (CO)
• Moisture (H₂O)
• Hydrocarbons (CH compounds)
• Residual sulfur or oil vapors

⚠️ Red flag: If a supplier simply says “purity: 99.995%” but provides no lab breakdown, it’s not a real COA.

2. Why Gas Purity Matters in Real-World Use

Low-purity N2O might not change the gas pressure—but it affects everything else:

• Taste (metallic or sour flavors)
• Whipped cream stability
• Siphon corrosion
• End-user health (if residual solvents or sulfur present)

💡 Fact: Some EU importers now legally require impurity data to approve shipment for food-grade sales.

3. Real COA Sample: What to Look For

Here’s a simplified version of a real N2O COA:

Compound	Max Limit (ppm)	Actual Test Result	Pass?
Oxygen (O₂)	≤ 5 ppm	1.2 ppm	✅
Moisture (H₂O)	≤ 2 ppm	0.4 ppm	✅
Hydrocarbons	≤ 1 ppm	0.6 ppm	✅
Carbon monoxide	≤ 1 ppm	0.2 ppm	✅

If your supplier can’t give you something like this—walk away.

📌 Tip: The COA should include:

• Lot number or batch code
• Analysis date
• Testing method (often gas chromatography)
• Certified lab or issuing body

4. How to Spot a Fake COA

Sadly, many “COAs” are just Word docs with no technical basis.

Red flags to watch:

• No issuing lab name
• No ppm values, only “PASS”
• No gas chromatography reference
• No date or batch number
• PDF looks like a photo of a catalog

💡 Tip: Cross-check with the factory’s real certificate (like FDA or CE) to ensure traceability.

5. Where to Use COA in Your Own Business

You don’t have to show customers every test result—but COA builds trust in:

• Distributor onboarding
• Amazon/eBay quality defense
• Foodservice contracts
• Legal compliance (especially in EU or AU)

✅ At nitronovae, we include COA with each bulk shipment and offer digital copies by batch.

6. Gas Grade Marking vs. Actual Purity

Just because the tank says “food-grade” doesn’t mean the gas was tested.

Label Type	What It Means	Trust Level
“Food-Grade N2O”	Marketing term	❌ Not enough
“99.995% Pure”	Often unverified	⚠️ Medium
COA with ppm breakdown	Real test results	✅ High
COA + Third-Party Lab	Certified purity	✅✅ Best

💡 Bonus: Ask for video of gas filling process + COA sticker on packaging. These are strong visual proof for retail buyers or regulators.

7. How to Request COA the Right Way

When working with a supplier, ask:

✅ “Do you provide a COA with gas chromatography report per batch?”

✅ “Which lab issues your report? Is it in-house or third-party?”

✅ “Can I see a sample COA from your last production?”

✅ “Do you match the COA batch code to the sticker on each tank or box?”

📌 At nitronovae, we match each COA to production batch ID and sticker barcode on the carton. That’s how we build traceable trust with our distributors.

Conclusion

Don’t let “99.995%” be just a number on a box. Real buyers verify, compare, and record. If you want your cream charger business to stand out in 2025—learn to read COA like a pro.
