Metotia o au'ili'iliga
Fa'amatalaga
Ave pe tusa ma le 10ml fa'ata'ita'iga ile ipu tioata mama ma mago ma siaki.
Ta'amilosaga fa'apitoa
Fa'asolo sa'o e tusa ma le 1.0g o le fa'ata'ita'iga ile 100ml volumetric flask ma fa'amavae i totonu10 ml o le chloroform, ona faʻafefiloi lea i le chloroform i le 100ml ma faʻafefiloi.
Fua le suiga mata'utia o le su'ega faataitai ile 25ºC ma le 589nm umi galufa'atatau le suiga ma'oti e tusa ai ma le fua fa'atatau.
[a]25D = (v×a)/[w×(1-b)]
[a]25D: o le suiga patino o le suʻegafa'ata'ita'iga;α: o le taamilosaga ua matauina i totonutikeri tulimanu;w: fa'ata'ita'iga mamafa (g);
v: voluma (mL);
e: vai (%)
