Standart echimlar CONCORD S050811, S050911 va boshqalar.

Standart titrlash eritmasi yuqori aniqlikdagi standart eritma bo'lib, konsentratsiya to'rtinchi kasrgacha aniq bo'lishi kerak. Suv, reagentlar va asboblar sifatini qat'iy nazorat qilish va kalibrlash tayyorgarlik yoki kalibrlash vaqtida amalga oshirilishi kerak.

Standart nopoklik eritmasi kimyoviy reagentlar va mahsulotlardagi nopoklik tarkibini konsentratsiyada aniq aniqlik bilan aniqlash uchun ishlatiladi. Ammo uni atom yutilish spektroskopiyasi, ion xromatografiyasi, plazma spektroskopiyasi, gaz xromatografiyasi va boshqalar uchun standart modda sifatida ishlatish mumkin emas, shuningdek kimyoviy reagentlar va kimyoviy mahsulot tarkibini aniqlash mumkin emas.
