   • Sanya sanannen adadin samfurin HPMC (yawanci gram 1-5) a cikin ƙugiya kuma yin rikodin haɗin haɗin samfurin da crucible (m2).
2. Tsarin toka:
   • Sanya crucible mai ɗauke da samfurin HPMC a cikin tanderun murfi ko tanderun toka.
   • Gasa tanderun sannu a hankali zuwa ƙayyadadden zafin jiki (yawanci 500-600 ° C) kuma kula da wannan zafin jiki na ɗan lokaci (yawanci awanni 2-4).
   • Tabbatar da cikakken konewa na kwayoyin halitta, barin a baya kawai ash inorganic.
3. Sanyaya da aunawa:
   • Bayan an gama aikin toka, cire ƙugiya daga tanderu ta amfani da tongs ko masu riƙewa.
   • Sanya crucible da abinda ke ciki a cikin injin bushewa don kwantar da zafin daki.
   • Da zarar an sanyaya, sake auna gwangwani da ragowar toka (m3).
4. Lissafi:
   • Ƙididdige abun ciki na ash na samfurin HPMC ta amfani da dabara mai zuwa: Abubuwan Ash (%) = [(m3 - m1) / (m2 - m1)] * 100
5. Tafsiri:
   • Sakamakon da aka samu yana wakiltar adadin abubuwan ash inorganic da ke cikin samfurin HPMC bayan konewa. Wannan ƙimar tana nuna tsabtar HPMC da adadin ragowar kayan da ba a haɗa su ba.
6. Rahoto:
   • Ba da rahoton ƙimar abun ciki na toka tare da kowane cikakkun bayanai masu dacewa kamar yanayin gwaji, gano samfurin, da hanyar da aka yi amfani da su.

Bayanan kula:

• Tabbatar cewa ƙugiya da murfi suna da tsabta kuma ba su da wata cuta kafin amfani.
• Yi amfani da murhu ko murhun toka tare da ikon sarrafa zafin jiki don tabbatar da dumama iri ɗaya da ingantaccen sakamako.
• Yi amfani da crucible da abinda ke ciki a hankali don gujewa asarar abu ko gurɓata.
• Yi aikin toka a wuri mai kyau don hana fallasa samfuran konewa.

Ta bin wannan hanya, zaku iya tantance daidaitattun ash abun ciki na samfuran Hydroxypropyl Methylcellulose (HPMC) da tantance tsaftarsu da ingancinsu.
