Ushbu maqolada moddalarni aniqlashning eng aniq usullaridan biri bo‘lgan mass-spektrometriya yordamida karbamid va furfurol asosida olingan birikma tekshirildi. Natijada, olingan kattaliklar asosida hosil bo‘lgan birikmaga tegishli molekulyar massalar aniqlandi. Ushbu birikmani termik jihatdan tahlil qilish natijasida uning erish harorati, harorat ta’sirida barqarorligi, harorat ta’sirida massa yo‘qotilishlari aniqlandi.
