      "question": "What does < LOQ mean on a COA?",
      "answer": "That the substance is below the lab''s limit of quantification (here 0.03%) and cannot be measured precisely."

      "answer": "Δ⁹-THC + 0.877 × THCA. For Helsama''s panel that comes to ≈ 0.25%, below the 0.3% limit."

  "content_markdown": "A COA (Certificate of Analysis) is the lab report showing exactly what a hemp product contains. The key part is the cannabinoid panel: which cannabinoids were detected and at what concentration (% of weight). Here is how to read it — using Helsama''s own analysis as an example.\n\n*Two independent HPLC analyses of the same hemp seed: 8.83% CBDA grown on Gotland vs 6.64% in Italy.*\n\n## What is a COA?\n\nA COA is the result from an independent laboratory that has measured a product''s cannabinoid content, usually using HPLC. It is the difference between a vendor claiming \"third-party tested\" and actually being able to show the numbers.\n\n## How do you read the cannabinoid panel?\n\nEach row is a cannabinoid with a measured concentration in % w/w (weight percent). Here is [Helsama''s panel](/en/kunskap/nordens-klimatfordel-cbda) (sample ID 2450024, HPLC):\n\n | Cannabinoid | Content (% w/w) | Uncertainty |\n| --- | --- | --- |\n\n | [CBDA](/en/kunskap/vad-ar-cbda) (cannabidiolic acid) | 8.83 | ±0.44 |\n\n | Δ⁹-THCA | 0.249 | ±0.042 |\n\n | CBD | 0.282 | ±0.042 |\n\n | CBGA | 0.154 | ±0.038 |\n\n | CBG | 0.031 | ±0.009 |\n\n | Δ⁹-THC | 0.031 | ±0.007 |\n\n | CBDV, THCV, CBN, Δ⁸-THC, etc. |\n\n**About Helsama’s Premium CBD Hampa:** Unheated raw hemp is the only way to buy legal full-spectrum CBD — extracted full-spectrum oils are classed as narcotics and isolate isn’t full-spectrum. Helsama’s Premium CBD Hampa is exactly that: unheated, milled raw hemp grown on Gotland, and we’re the only ones selling the CBD hemp varieties grown in Scandinavia. The Nordic summer’s long light — up to 18 hours of daylight — makes the hemp special: our third-party analyses show 8.83% CBDA versus 6.64% for the same seed grown in Italy.
