Indlela yokukhetha i-analyzer ye-biochemical efanelekileyo

Abahlalutyi be-Biochemistry, abakwabizwa ngokuba ngabahlalutyi bekhemistri yeklinikhi, basetyenziselwa ukulinganisa i-metabolites kwiisampulu zebhayoloji njengegazi okanye umchamo.Uphando lwale ncindi luvumela ukuxilongwa kwezifo ezininzi.Umzekelo wokusebenzisa i-analyzer enjalo kukulinganisa i-creatinine yomchamo ukuvavanya amandla okucoca intso.
Xa ukhetha i-analyzer ye-biochemical, kubalulekile ukuqwalasela ukuba ngaba i-assay automation iyadingeka, ukuchaneka kwee-reagents, kunye nezinga lokuchaneka komlinganiselo.Kwakhona kubalulekile ukuqwalasela umthamo wokufumanisa (ubuninzi benani leesampuli ezihlalutyiweyo ngaxeshanye).

Yeyiphi indlela yokulinganisa esetyenziswa sisihlalutyi sezinto eziphilayo?

Kukho iindlela ezininzi zokulinganisa uhlalutyo.Zinokwahlulwa zibe ziindidi ezimbini:

Ubuchule bokubona:
I-Colorimetry: Le yeyona ndlela isetyenziswa kakhulu.Xuba isampuli kunye ne-reagent efanelekileyo ukuvelisa ukusabela kombala.Uxinzelelo lwe-analyte lumisela ubunzulu bombala ofunyenweyo.
Ifotoometry: umthombo wokukhanya uqikelelwa kwisampulu enobude obufanelekileyo, ngelixa i-photodetector ibekwe kwelinye icala lesampulu ilinganisa ubungakanani bokufunxwa kokukhanya.Oku kuhambelana ngokuthe ngqo nokugxilwa kwe-analyte kwisampuli.Nantsi imigaqo emininzi: i-absorbence (ubuchule bezinto eziphakathi ukufunxa ukukhanya), i-turbidity (elinganisa i-turbidity eveliswa yinto exhonywe kumanzi olwelo), i-fluorescence (ubungakanani bokukhanya into efunxayo kubude obunye kwaye iphume kwenye. ).

Ubuchwephesha be-Electrochemical:
I-potentiometry ethe ngqo: i-ion selective electrode (ISEs) isetyenziswa ngokubanzi, ngokukodwa ukumisela isixa seeoni kwiisampulu.Indlela yaphuhliswa ukumiselwa kwe-sodium, i-potassium, i-chloride kunye ne-lithium ion.I-ion electrode ekhethiweyo yinzwa ekwazi ukumisela ukuxinwa kwee-ion kwisisombululo ngokulinganisa i-current flowing through ion selective membrane.
I-potentiometry engathanga ngqo: le ndlela ikwasebenzisa i-electrode ekhethiweyo ye-ion.Ivumela inani elikhulu lovavanyo kwaye isetyenziswa ngokuqhelekileyo kwiilabhoratri ezisembindini.Ngokungafaniyo ne-potentiometry ethe ngqo, ifuna i-pre dilution, echazwe kwi-molarity, ukuvakalisa iziphumo.
Abahlalutyi be-Biochemicals banokubonelela ngemigaqo emininzi yokulinganisa.

Ziziphi iinketho ezikhoyo kubahlalutyi be-biochemical?

Ezinye iimodeli zibonelela ngoluhlu olubanzi lweentlobo zokuhlalutya kunabahlalutyi abaqhelekileyo.Zingasetyenziswa kwiindawo zobungcali ezifana ne-immunology, i-endocrinology, i-toxicology, kunye ne-oncology.Kukho iimodeli kwiimarike ezivumela ukuya kwiintlobo ze-100 zokuhlalutya.Ukwandisa ukuhamba komsebenzi, kukwakho neenkqubo zokusebenzisa ikhemistri yeklinikhi kunye neesampulu ze-immunoassay ngaxeshanye.Ngale ndlela, akukho mfuneko yokucubungula iisampuli phakathi kweemodyuli ezahlukeneyo.
