Yintoni umahluko phakathi kwe-TC sensor kunye ne-IR sensor kwi-CO₂ incubator?

Xa kukhuliswa ii-cell cultures, ukuqinisekisa ukukhula okufanelekileyo, ubushushu, ukufuma, kunye namanqanaba e-CO2 kufuneka kulawulwe. Amanqanaba e-CO2 abalulekile kuba anceda ukulawula i-pH yendawo yokukhulisa izityalo. Ukuba kukho i-CO2 eninzi kakhulu, iya kuba ne-asidi kakhulu. Ukuba akukho CO2 yaneleyo, iya kuba ne-alkaline ngakumbi.

Kwi-akhawunti yakhoIsifukamisi se-CO2, inqanaba legesi ye-CO2 kwindawo ephakathi lilawulwa kukunikezelwa kwe-CO2 kwigumbi. Umbuzo ngulo, inkqubo "yazi njani" ukuba ingakanani i-CO2 ekufuneka yongezwe? Kulapho ubuchwepheshe be-sensor ye-CO2 buqala khona ukusebenza.

Kukho iintlobo ezimbini eziphambili, nganye ineengenelo kunye neengxaki zayo:

* Ukuqhuba ubushushu kusebenzisa i-thermal resistor ukubona ukwakheka kwegesi. Lukhetho olungabizi kakhulu kodwa aluthembekanga kangako.

* Iisensa ze-CO2 ezifakwe kwi-infrared zisebenzisa ukukhanya kwe-infrared ukubona ubungakanani be-CO2 kwigumbi. Olu hlobo lwesensa lubiza kakhulu kodwa luchaneke ngakumbi.

Kule posi, siza kuchaza ezi ntlobo zimbini zesenzi ngokweenkcukacha kwaye sixoxe ngeziphumo ezisebenzayo zalo ngalinye.

Inzwa ye-CO2 yokuqhuba ubushushu

Ukuqhuba kobushushu kusebenza ngokulinganisa ukumelana nombane emoyeni. I-sensor ihlala iqulathe iiseli ezimbini, enye yazo izaliswe ngumoya ovela kwigumbi lokukhula. Enye yiseli evaliweyo equlathe umoya obhekisayo kubushushu obulawulwayo. Iseli nganye ine-thermistor (i-thermal resistor), ukumelana kwayo kutshintsha ngobushushu, ukufuma, kunye nokwakheka kwegesi.

Ukubonakaliswa kwesenzi sokuqhuba ubushushu

Xa ubushushu kunye nokufuma kufana kuzo zombini iiseli, umahluko wokuxhathisa uya kulinganisa umahluko kulwakhiwo lwegesi, kule meko ubonisa inqanaba le-CO2 kwigumbi. Ukuba umahluko ufunyenwe, inkqubo iyacelwa ukuba yongeze i-CO2 engaphezulu kwigumbi.

Umzobo we-sensor ye-thermal conductivity.

Ii-conductors ze-thermal ziyindlela engabizi kakhulu kunee-IR sensors, esiza kuxoxa ngazo ngezantsi. Nangona kunjalo, azizi ngaphandle kweengxaki zazo. Ngenxa yokuba umahluko wokuxhathisa unokuchaphazeleka zezinye izinto ngaphandle kwamanqanaba e-CO2 kuphela, ubushushu kunye nokufuma kwigumbi kufuneka kuhlale kungaguquguquki ukuze inkqubo isebenze ngokufanelekileyo.

Oku kuthetha ukuba ngalo lonke ixesha ucango luvuleka kwaye ubushushu kunye nokufuma kutshintshatshintsha, uza kugqibela unezibalo ezingachanekanga. Enyanisweni, izibalo aziyi kuba zichanekile de kube umoya uzinze, nto leyo engathatha isiqingatha seyure okanye ngaphezulu. Ii-thermal conductors zinokuba zilungile ekugcinweni kwee-cultures ixesha elide, kodwa azifanelekanga kangako kwiimeko apho ukuvuleka kweminyango kuxhaphake khona (ngaphezu kwesinye ngosuku).

Izinzwa ze-CO2 ze-infrared

Izinzwa ze-infrared zibona ubungakanani begesi kwigumbi ngendlela eyahlukileyo ngokupheleleyo. Ezi sensors zixhomekeke kwinto yokuba i-CO2, njengezinye iigesi, ifunxa ubude bokukhanya obuthile, obuyi-4.3 μm ukuze kube ngokuchanekileyo.

Umzobo we-sensor ye-Infrared

I-sensor inokubona ukuba ingakanani i-CO2 ekwi-atmosphere ngokulinganisa ukuba ingakanani i-4.3 μm yokukhanya edlula kuyo. Umahluko omkhulu apha kukuba ubungakanani bokukhanya obufunyenweyo abuxhomekekanga kwezinye izinto, ezifana nobushushu kunye nokufuma, njengoko kunjalo ngokumelana nobushushu.

Oku kuthetha ukuba ungawuvula ucango amaxesha amaninzi kangangoko ufuna kwaye i-sensor iya kuhlala inika ukufundwa okuchanekileyo. Ngenxa yoko, uya kuba nenqanaba elihambelanayo le-CO2 kwigumbi, oko kuthetha ukuzinza okungcono kweesampuli.

Nangona ixabiso lee-infrared sensors lehlile, zisabonisa enye indlela ebiza kakhulu endaweni ye-thermal conductivity. Nangona kunjalo, ukuba ucinga ngexabiso lokungabikho kwemveliso xa usebenzisa i-thermal conductivity sensor, usenokuba netyala lemali lokusebenzisa i-IR option.

Zombini ezi ntlobo zeesensa ziyakwazi ukubona inqanaba le-CO2 kwigumbi le-incubator. Umahluko omkhulu phakathi kwezi zimbini kukuba isensa yobushushu inokuchaphazeleka zizinto ezininzi, ngelixa isensa ye-IR ichaphazeleka linqanaba le-CO2 lodwa.

Oku kwenza ii-sensors ze-IR CO2 zichaneke ngakumbi, ngoko ke zikhethwa kakhulu kwiimeko ezininzi. Zihlala zinexabiso eliphezulu, kodwa ziya zisiba zixabiso eliphantsi njengoko ixesha lihamba.
