📝 AAS parametrlari izohi

  • FAAS (Flame AAS): Havo-atsetilen (~2300°C) yoki N₂O-atsetilen (~2900°C). LOD: 0.001−0.05 mg/L (ppm).
  • GFAAS (Graphite Furnace): Grafit pechi, dasturlanadigan harorat. LOD: 0.01−1 μg/L (ppb).
  • HGAAS (Hydride Generation): NaBH₄ bilan MH₃ gidridi. LOD: 0.001−0.1 μg/L (ppt). Faqat As, Se, Sb, Bi, Sn, Te.
  • LOD: Aniqlash chegarasi (S/N = 3)
  • LOQ: Miqdoriy aniqlash (S/N = 10) ≈ 3.3 × LOD
  • RSD: Nisbiy standart og'ish (5 ta parallel, ≤ 2% yaxshi)
  • Δ: Nazariy va eksperimental %M farqi (≤ 0.5% = tasdiqlangan)
  • Modifikator: GFAAS da uchuvchanlikni kamaytiruvchi qo'shimcha

⚖️ AAS vs EA (Element Analiz) — bu sahifa EA dan qanday farq qiladi?

🧪 EA (Element Analiz)

  • ✓ C, H, N, S — organik elementlar
  • ✓ Ligandlar tarkibini aniqlaydi
  • ✗ Metallarni o'lchay olmaydi
  • ✓ Butun formula validatsiyasi

🧯 AAS (Atom-Absorbsion)

  • ✓ Metallar — Fe, Cu, Pt, Au, Cd va h.k.
  • ✗ Ligandlar tarkibini bilmaydi
  • ✓ Juda yuqori sezgirlik (ppb-ppt)
  • ✓ Formula metall qismini tasdiqlaydi

💡 Ideal tahlil: EA + AAS (yoki ICP-OES) birgalikda — to'liq formula validatsiyasi. EA organik qismini (ligandlarni), AAS metall qismini tasdiqlaydi.
