Tikanga tātari
Whakaahuatanga
Tangohia he tauira 10ml ki roto i te pereti karaihe ma, maroke ka tirohia.
Te hurihanga motuhake
Whakawhiti tika mo te 1.0 karamu o te tauira ki te 100ml ipu rōrahi ka rewa ki roto10 ml o te chloroform, ka waimeha ki te chloroform ki te 100ml ka uru.
Ine i te hurihanga whatu o te tauira whakamatautau ki te 25ºC me te 589nm roangarutātaihia te hurihanga motuhake kia rite ki te tātai kua hoatu.
