Amino Acids kale
Qaado qadar ku habboon alaabtan, ku dar biyo si aad u milmaan oo u milo si aad u samayso xal ka kooban 20mg halkii lml sida xal tijaabo ah;Qaado 1ml si aad u cabbirto saxda ah oo ku rid weel cabbir ah 200ml, ku walaaq miisaanka biyaha, si fiican u rux, sida xal xakamaynta;Qaado qaddarka saxda ah ee tixraaca serine iyo tixraaca methionine siday u kala horreeyaan, oo ku rid isla weelka cabbirka, biyaha ayaa lagu daray in la milmaan oo la qaso si loo diyaariyo xal ka kooban 0.4mg midkiiba 1ml sidii xal ku habboon nidaamka.Marka loo eego chromatography lakabka khafiifka ah (General 0502), nuugo saddexda xal ee kor ku xusan mid kasta 5 u1, siday u kala horreeyaan, isla silica gel G saxan lakab khafiif ah, oo leh n-butanol-water-glacial acetic acid (3: 1: 1) horumarinta, ka dib marka la geeyo, qalajinta hawada, ku buufinta ninhydrin ee dareeraha acetone (1-50), kuleylinta 80 ° C ilaa dhibco ka soo baxaan, iyo baaritaanka isla markiiba.Xalka xakamaynta waa inuu muujiyaa meel cad, iyo nidaamka xalka lagu dabaqi karo waa inuu muujiyaa laba dhibcood oo gebi ahaanba kala duwan.Haddii xalka imtixaanku muujiyo dhibco wasakhaysan, midabku waa inaanu ka qoto dheerayn (0.5%) marka loo eego meesha ugu muhiimsan ee xalka xakamaynta.
Khasaare xagga qalajinta
Qaado alaabtan, qallaji at 105 ℃ 3 saacadood, luminta miisaanka waa in aanu dhaafin 0.2% (Sharciga Guud 0831).
Hadhaaga dabka
Aan ka badnayn 0.1% (xeerka guud 0841).
Cusbada Birta
Qaado 1.0g oo alaabtan ah oo hubi si waafaqsan sharciga (Xeerka Guud 0807).Marka la barbardhigo xalka xakamaynta ee laga sameeyay 0.001% ee xalalka birta caadiga ah, ma noqon doonto mid qoto dheer ().
Biraha culus
Qaado 2.G ee alaabtan, ku dar 23ml oo biyo ah si aad u milmaan, ku dar 2ml of acetate buffer (pH3.5), oo hubi sida waafaqsan sharciga (sharciga koowaad ee xeerarka guud 0821), oo ay ku jiraan biraha culus waa in aanay dhaafin 10 qaybood halkii milyan.
Cusbada Arsenic
Qaado alaabtan 2. G, ku dar biyo 23ml milmay, ku dar hydrochloric acid 5ml, marka loo eego kormeerka sharciga (Mabaadi'da Guud 0822 sharciga koowaad), waa in ay u hoggaansamaan qodobada (0.0001%).
Bakteeriyada Endotoxin
Qaado alaabtan, hubi sida waafaqsan sharciga (Guud 1143), qadarka endotoxin ee serine kasta lg waa inuu ka yaraado 12EU.(Dirridda)
312-84-5 - Go'aaminta nuxurka
Qaado alaabtan qiyaastii 0.1g, miisaan sax ah, ku dar anhydrous formic acid 1 ml si ay u milmaan, ku dar glacial acetic acid 25ml, marka loo eego habka titration potentiometric (General 0701), oo leh xalka titration perchloric acid (0.1 mol/L), iyo Natiijooyinka titration-ka ayaa lagu saxay imtixaan maran.Mid kasta oo 1 ml oo ah xalalka titration perchloric acid (0.1 mol/L) waxay u dhigantaa 10.51 mg ee C3H7N03.
