Zofunikira za reagent ndi chifaniziro choyambirira cha ndende ya yankho.

2022-12-23

Madzi ogwiritsidwa ntchito munjira yoyesera amatanthauza madzi osungunuka kapena madzi osungunuka ngati palibe zofunikira zina zomwe zawonetsedwa. Pamene chosungunulira cha yankho sichinatchulidwe, chimatanthawuza njira yamadzimadzi. Pamene ndende yeniyeni ya H2SO4, HNO3, HCL ndi NH3 · H2O siinatchulidwe mu njira yoyesera, zonse zimatanthawuza kuchuluka kwa malonda omwe alipo. Dontho lamadzimadzi limatanthawuza kuchuluka kwa dontho la madzi osungunuka omwe amayenda kuchokera ku dontho lokhazikika, lomwe ndi lofanana ndi 1.0mL pa 20 ° C.

Kukhazikika kwa mayankho kumatha kuwonetsedwa motere:
â Kufika pamlingo wokhazikika (ndiko kuti, kuchuluka kwa chinthu) : kumatanthauzidwa ngati kuchuluka kwa zinthu zomwe zili ndi solute mu voliyumu ya yankho, chigawocho ndi Mol/L

â¡ Molingana ndi ndende: ndiye kuti, mumitundu ingapo yolimba ya reagent yosakanikirana kapena nambala ya voliyumu yamadzimadzi, imatha kulembedwa ngati (1 1) (4 2 1) ndi mitundu ina.

â¢ Pa gawo la misa (voliyumu): pa solute amawerengera gawo lalikulu kapena gawo lachidule la mawu a yankho, atha kutchulidwa kuti w kapena Phi.

(4) Ngati njira yothetsera vutoli ikuwonetsedwa mumagulu a misa ndi mphamvu, ikhoza kuwonetsedwa ngati g / L kapena ndi angapo oyenerera (monga mg / mL).

Zofunikira ndi zofunikira zina pokonzekera yankho:
Kuyera kwa reagents ndi zosungunulira zomwe zimagwiritsidwa ntchito pokonzekera yankho ziyenera kukwaniritsa zofunikira za chinthu chowunikira. Ma reagents okhazikika amasungidwa m'mabotolo agalasi olimba, mayankho a lye ndi zitsulo amasungidwa m'mabotolo a polyethylene, ndipo ma reagents a photoproof amasungidwa m'mabotolo abulauni.

Mayeso ofanana ayenera kupangidwa poyendera. Kuyimilira kwa zotsatira zoyendera kuyenera kukhala kogwirizana ndi kuyimira kwa miyezo yaukhondo wa chakudya, ndipo kuwerengera ndi mtengo wa deta kuyenera kutsatira lamulo la ziwerengero zazikulu ndi lamulo la kusankha nambala.

Njira yowunikirayi iyenera kuchitidwa motsatira njira zowunikira zomwe zafotokozedwa mu muyezo, ndipo njira zodzitchinjiriza ziyenera kuchitidwa pazinthu zosatetezeka (poizoni, kuphulika, dzimbiri, kutentha, ndi zina) pakuyesa. Laboratory yoyendera thupi ndi mankhwala imagwiritsa ntchito kuwongolera khalidwe. Kutengera kukhazikitsidwa kwaukadaulo wabwino, njira yotsimikizika iyenera kukhala ndi malire ozindikira, kulondola, kulondola, kujambula deta yokhazikika pamapindikira ndi zina zaukadaulo. Oyang'anira ayenera kudzaza zolemba zoyendera.

Zam'mbuyo:Kodi nchifukwa ninji chikhalidwe cha ma cell chimasokoneza maselo ofiira a magazi poyamba?

Ena:Kodi mbale ya PCR ndi chiyani
