Mazkur maqolada benzin tarkibidagi umumiy kislorod miqdorini aniqlashning zamonaviy analitik usullari
ko‘rib chiqiladi: gaz xromatografiyasi asosidagi individual oksigenatlarni aniqlash usuli (ASTM D 4815), kislorodga selektiv
alanga-ionlanish detektorli gaz xromatografiya usuli (ASTM D 5599) va yordamchi ekspress usullar (FTIR spektroskopiya,
elementar tahlil). Benzinga oksigenatlar (metanol, etanol, MUBE, EUBE va boshqalar) qo‘shilishining texnologik va
ekologik sabablari, ularning oktan sonini oshirish hamda zararli chiqindilarni kamaytirishdagi roli tahlil qilinadi. Individual
komponentlar asosida umumiy kislorod miqdorini hisoblash formulasi keltiriladi, usullarning aniqligi va qo‘llanilish
sohalari taqqoslanadi, shuningdek, benzin tarkibidagi kislorod miqdorining me’yoriy hujjatlar (ASTM D 4814) talablariga
muvofiqligini nazorat qilish masalalari yoritiladi.
