Sastāvdaļas vai rekvizīti (vai nu tīri vai jaukti); gāzes analīze sastāvu var mērīt ar ķīmisko adsorbciju, sadedzināšanas, electrochemical šūnas, indikatoru papīri, hromatogrāfija, masu spektroskopijas un tā tālāk; rekvizītus analizē arī apkures vērtību, molekulmasa, blīvums un viskozitāte.
Industry:Chemistry
Instrumentam, ko izmanto gāzu hromatogrāfiju, noteikt gaistošo savienojumu klāt; izmanto arī, lai noteiktu konkrētu fizikālās īpašības, piemēram, izplatīšanas vai sadalīšanās koeficientu un adsorbcijas izotermas un kā preparative paņēmiens, izolējot tīras sastāvdaļas vai dažu frakciju no komplekss maisījumus.
