I-20Ml scintilutiction i-vials yokusetyenziswa kwesikhokelo: Iimpazamo ezi-5 zovavanyo kunye nezisombululo
Eli nqaku lijolise ekuncedeni abaphandi belebhoratri ekuchongeni nasekulungiseleleni iimpazamo ezintlanu zomsebenzi ezinxulumene nokusetyenziswa kwe-20ml ye-screentictions kuhlalutyo lwesampulu ye-radiod.
Ukusetyenziswa okuncinci okuncinci, njengokutywina okungafanelekanga okanye ukucoceka okungafanelekanga, kunokukhokelela ekunxaxheni kwedatha enkulu, kunye nezifundo ezibonisa ukuba kukho umahluko wama-30% kwiziphumo.
Eli nqaku lichitha kwimicimbi efana nezakhono zokutywina, qalisa uku-vishari eziphathwayo, ukutyeshela ulungelelwaniso lwekhemikhali phakathi kwezixhobo ze-Vial kunye neRegents, indawo engalunganga ekhokelela kungcoliseko.
Ngokunikezela ngezisombululo ezineenkcukacha kunye nedatha yovavanyo, eli nqaku likhokela abaphandi ekufezekiseni iinkqubo zabo zovavanyo ukuqinisekisa ukuchaneka kwedatha kunye nokuthembeka.
1. Intshayelelo: Iimpazamo ezincinci, iziphumo eziphambili
Kuhlalutyo lwesampulu ye-radious, ukuguqulwa okuncinci kwe-20ml yespikintil kungakhokelela ekuphathweni kwedatha ukuya kuthi ga kwi-30%, kunye nabaphandi abaninzi bengazi imiba ephantsi.
Ngokwedatha evela kubathengisi bamanye amazwe anjengenzululwazi ye-thomas, ukusetyenziswa gwenxa kwee-vials zescinilting zeakhawunti ukuya kwi-17% yamaxabiso aphindaphindwayo.
2. Iimpazamo ezihlanu neziqhelekileyo kunye nezisombululo zabo
Impazamo yoku-1: Ukutywina okungaphelelanga kukhokelela kwisampuli yovavanyo
Imeko eqhelekileyo: Ukujikeleza i-cap nge-1 \ / 4 jika, ukusilela ukufezekisa uyilo lwe-CS222 yoyilo lwe-3 \ / 4 Guqula umgangatho wokutywina.
-
Ixabiso lemvelaphi eliphakanyisiweyo kwi-β-ray fumanela.
-
Amanqanaba okubalwa okugqwethekileyo kwiisampulu zomsebenzi ophantsi.
Isisombululo: Qinisekisa ukuba i-cap iqinile kumgangatho woyilo, usebenzisa i-CAPS nge-Polythyethylene Cone Liners yokuphucula ingqibelelo yokuthengisa.
Impazamo 2: Ukuqesha i-vials ngaphandle kokucoca ngokucokisekileyo
Ingozi yentsalela: Intsalela ye-Teluene esekwe kwi-scinesiltiltion i-scimiltives i-strolives inokuthi inqamle ii-regents zokuhamba kwamanzi.
Iingcebiso zokucoca:
| Isixhobo | Iarhente yokucoca icetyiswayo | Awona maxesha aphezulu |
|---|---|---|
| Iglasi (vs2017) | Chromic acid ihlambe → Amanzi okugqibela | Amaxesha angama-50 |
| I-HDPE | I-Ethanol Ultrasonnic → i-nitrogen yomile | Amaxesha angama-30 |
Khetha iindlela ezifanelekileyo zokucoca ngokusekwe kwizixhobo ukuqinisekisa ukuba imeko icocekile.
Impazamo yesi-3: Ukutyeshela ulungelelwaniso lwekhemikhali phakathi kwezinto ze-Vial kunye ne-Regegents
Thelekisa ukuthelekisa:
| Uhlobo lwe-regent | Iglasi | I-HDPE | Isilwanyana sasekhaya | I-PP |
|---|---|---|---|---|
| I-toluene \ / xylene | ✓✓✓ | ✓✓ | ✗ | ✓✓✓ |
| I-acid eyomeleleyo (PH <2) | ✓✓✓ | ✗ | ✗ | ✓✓ |
| I-acetone | ✓✓ | ✓✓✓ | ✓✓ | ✓✓ |
Khetha izixhobo ze-vials zihambelana nee-regents zakho ukuthintela ukuphendula kwekhemikhali ezinokuthi zichaphazele iziphumo zovavanyo.
Impazamo yesi-4: Ukugcinwa okungafanelekanga okukhokelela kungcoliseko lomzimba
Ukuthelekisa ityala:
-
Ukugcina nkqo i-vs. Ukugcinwa ngokuthe tyaba okukhokelela kwi-crystalizer kumlomo we-vial.
-
Ukukhusela ukukhanya kokukhanya okubangela ingxolo yangasemva ye-fluorescent.
Ingcebiso: Khetha iinguqulelo ze-brown ezimdaka (vs2017b) okanye i-HDPE-khupha i-vils yokukhusela ukukhanya kwe-vials ukuphatha iisampulu ezibuthathaka.
Impazamo yesi-5: I-Progudgment yeGuqulelo ekhokelela kwifuthe lokuhamba
Idatha ephambili: Xa i-vienition yokugcwalisa i-20ml igqitha i-18ml, impumelelo yokufumana impumelelo ye-scintilution yescreyiting yentlukwano kuncipha nge-12-16%.
Umgangatho wokuSebenza: Sebenzisa indlela yokumakisha igxalaba ukuqinisekisa ukuba ivolumu yokuzalisa inoluhlu olucetyiswayo.
I-3. Ukuqinisekiswa kovavanyo kunye nenkxaso yedatha yobugcisa
-
Iimvavanyo zomntu wesithathu zibonisa ukuba zisebenzisa iziphumo ezitywiniweyo ze-CS222 ze-CSIII ze-Triium-i-leaberation enemigangatho yelahleko engaphantsi kwe-0.5% ngaphezulu kweeveki ezisi-8, xa kuthelekiswa ne-7.2% nge-COPS eqhelekileyo.
-
Izixhobo zeglasi vs2017 imiboniso ye-zero yokuqhekeka kwi-Deageages yobushushu isusela kwi-196 ° C ukuya kwi-150 ° C, ukuqinisekisa ukuzinza phantsi kweemeko ezithile.
