Kev Siv
Nws tau teev tseg ua ib qho tshuaj tsw qab uas raug tso cai rau hauv GB2760—96. Nws feem ntau siv rau hauv cov tshuaj tsw qab thiab hauv kev npaj cov roj tseem ceeb (xws li roj geranium) ua ib feem ntawm cov ntawv sau saum toj kawg nkaus. Nws kuj tseem siv tau me me hauv cov tshuaj tsw qab violet, osmanthus, magnolia, thiab ylang-ylang kom hloov kho lossis txhim kho cov ntxhiab tsw tshiab thiab mos. Tsis tas li ntawd, nws tuaj yeem siv me me hauv cov qauv khoom noj rau txiv maj phaub, txiv hmab txiv ntoo, thiab ntau yam txiv hmab txiv ntoo tsw qab.
Cov qauv tshuaj ntsuam xyuas roj chromatography. Kev sib cais ntawm lithium chloride los ntawm potassium chloride thiab sodium chloride. Cov kuab tshuaj.
Ntim thiab Xa Khoom
Ntim: 170KG / nruas lossis raws li cov neeg siv khoom xav tau.
Kev xa khoom: yog cov tshuaj lom neeg thiab tuaj yeem xa los ntawm tsheb ciav hlau, dej hiav txwv thiab huab cua.
