Chloride
Qaado 0.30g ee alaabtan oo hubi si waafaqsan sharciga (Xeerka Guud 0801).Marka la barbar dhigo xalka kantaroolka ee laga sameeyay 6.0ml ee xalka sodium chloride caadiga ah, waa inuusan noqon mid aad u badan (0.02%).
Sulfate
Qaado 0.50g oo badeecadan ah, ku dar 2ml of hydrochloric acid iyo 5ml oo biyo ah, rux si aad u milanto, hubi sida uu qabo sharciga (Xeerka Guud 0802), oo barbar dhig xalka kantaroolka ee laga sameeyay xalalka potassium sulfate ee caadiga ah, oo aan xoog lahayn (0.02). %)
Cusbada Ammonium
Qaado 0.10g ee alaabtan oo hubi si waafaqsan sharciga (Xeerka Guud 0808).Marka la barbar dhigo xalka kantaroolka ee laga sameeyay 0.02% ee xalka ammonium chloride caadiga ah, ma noqon doono mid qoto dheer ().
Amino Acids kale
Qaado alaabtan, ku dar 0.5mol/L hydrochloric acid si aad u milmaan oo aad u milo si aad u diyaarisid xal ka kooban 10 mg halkii 1ml sida xal tijaabo ah;Qaado 1ml cabbirka saxda ah, ku jira 0.5 weel lagu cabbiro, ku milo miisaanka mol/L hydrochloric acid xal, si fiican u rux, oo u isticmaal xal kontorool, A 0.5mol/L hydrochloric acid ayaa lagu daray, milmay oo la qasi jiray si loogu diyaariyo xal ka kooban qiyaastii 10 mg oo glutamic acid ah iyo MG of aspartic acid per 1ml, siday u kala horreeyaan, sida nidaam ku habboon xal.Marka loo eego tijaabada lakabka khafiifka ah ee chromatography (General 0502), ku sawir 5ul mid kasta oo ka mid ah saddexda xal ee kor ku xusan, siday u kala horreeyaan, isla silica gel G saxan lakab khafiif ah, oo leh n-butanol-water-glacial acetic acid (2:1:1). ) si ay u horumariyaan, u faafiyaan, u qallajiyaan, ugu buufin ninhydrin oo ku jira xal acetone (1-50), kulaylka 80 ° C ilaa ay dhibco ka soo baxaan, oo isla markiiba kormeer.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, engegan ilaa miisaan joogto ah at 105 ℃, miisaan lumis waa in aanay ka badan 0.5% (Xeerka Guud 0831).
Hadhaaga dabka (sida Sulfated)
Qaado l.0g ee alaabtan oo hubi si waafaqsan sharciga (Xeerka Guud 0841).Inta hadhay waa in aanay ka badnayn 0.1%.
Cusbada Birta
Qaado 2.0g oo badeecadan ah, ku dar 6mL oo ah aashitada hydrochloric-ka ah iyo xaddi ku habboon oo biyo ah, kulayl si ay u milaan, u qaboojiso, ku dar biyo 25ml, oo hubi sida uu qabo sharciga (Xeerka Guud 0807), waa in aanu noqon mid qoto dheer (0.0005% ) marka loo eego xalalka xakamaynta ee ka samaysan birta caadiga ah.
Biraha culus
Hadhaaga ku hadhay shayga qaadashada haraaga dabka waa in aanu ka koobnaan in ka badan 10 qaybood halkii milyan oo bir culus ah marka sharcigu eego (Mabaadi'da Guud 0821, Law II).
Cusbada Arsenic
Qaado 2.0g oo badeecadan ah, ku dar 5ml oo ah hydrochloric acid iyo 23ml oo biyo ah si aad u milanto, hubi sida uu qabo sharciga (Mabaadi'da Guud 0822 sharciga koowaad), waa in ay raacaan qodobada (0.0001%).
Pyrogen
Alaabtan waxaa lagu qasi jiray duritaanka sodium chloride si loo sameeyo xal ka kooban 20mg halkii lml, kulayl si ay u milaan, ha qaboojiso 37 ° C, oo hubi sida waafaqsan sharciga (Xeerka Guud 1142), qiyaasta miisaanka jidhka bakayle per lkg 10ml , waa in ay u hoggaansamaan qodobada.(Dirridda)
56-86-0 - Go'aaminta nuxurka
Qaado alaabtan qiyaastii 0.25g, miisaan sax ah, ku dar biyo karkaraya 50ml si aad u milmaan, qaboojiso, ku dar 5 dhibcood oo ah bromothymol xal tusaha buluuga ah, oo isticmaal titration sodium hydroxide (0.1 mol/L) titration ilaa xalka huruud ilaa buluug- cagaar.Mid kasta oo 1 ml oo ah xalka titration sodium hydroxide (0.1 mol/L) waxay u dhigantaa 14.71mg ee C5H9N04.
