Umhlahlandlela we-20ML Scintillation Vials Ukusetshenziswa Okusetshenziswayo: 5 Amaphutha ajwayelekile wokuhlola kanye nezixazululo
Lo mbhalo uhlose ukusiza abacwaningi belebhu ekuboneni nasekulungiseni amaphutha amahlanu ajwayelekile okusebenza ahambisana nokusetshenziswa kwama-20ms scintillation vers ekuhlaziyweni kwesampula yesampula yemisakazo.
Ama-Mishandlings amancane, njengokubekwa uphawu okungafanele noma ukuhlanza okunganele, kungaholela ekuphambukeni okubalulekile kwedatha, ngezifundo ezibonisa umehluko ongu-30% ngemiphumela.
I-athikili idlulela izingqinamba njengokungalingani kokungalingani kokunganakwa, ukusebenziseka kabusha kwama-vials angcolile, kunganaki ukuhambisana kwamakhemikhali phakathi kwezinto zokwakha kanye nama-reagents, isitoreji esingafanele esiholela ekungcolisweni, kanye nokuhlehlisa amavolumu okubangela imiphumela eqeda imiphumela.
Ngokunikeza izixazululo ezinemininingwane nemininingwane yokuqinisekisa yokuhlola, i-athikili iqondisa abaphenyi ekwakheni izinqubo zabo zokuhlola ukuqinisekisa ukunemba kwedatha nokwethembeka.
1. Isingeniso: Amaphutha amancane, imiphumela emikhulu
Ekuhlaziyweni kwesampula yesampula yemisakazo, ama-mishandlings amancane we-20ml scintillation vials angaholela ekuphambukeni kwedatha okufika kuma-30%, abaphenyi abaningi abazi ngezinkinga eziyisisekelo.
Ngokwemininingwane evela kubahlinzeki bamazwe aphesheya abanjengeThomas Science Science, ukusetshenziswa okungafanele kwama-akhawunti we-scintillation vials afinyelela ku-17% wamanani wokuphindaphinda kokuhlola.
2. Amaphutha amahlanu ajwayelekile nezixazululo zawo
Iphutha 1: Ukubekwa uphawu okunganele okuholela ekuguqukeni kwesampula
Isimo esijwayelekile: Ukujikeleza kuphela i-cap nge-1 \ 4 Jist, ukwehluleka ukufeza isilinganiso se-CS222 cap design 3 \ 4 jikisa
-
Amanani angemuva aphakeme ekutholweni kwe-β-ray.
-
Amanani okubala ahlanekezelwe kumasampula aphansi aphansi.
Isixazululo: Qinisekisa ukuthi i-cap iqiniswa ezilinganisweni zedizayini, isebenzisa ama-cap nge-polyethylene cone liners ukuthuthukisa ubuqotho bokuvalwa kokubekwa uphawu.
Iphutha 2: Ukusebenzisa kabusha izimbotshana ngaphandle kokuhlanza ngokuphelele
Izingozi ezisele: Izinsalela ze-TOLUENE-based Scintillation Liquid Izinsalela zingasusa ama-reagents angenamanzi.
Izincomo Zokuhlanza:
| Into uqobo lwayo | Inconyelwe ukuhlanza i-ejenti | Izikhathi eziningi zokuphinda uphinde |
|---|---|---|
| Ingilazi (vs2017) | Ukugeza kwe-Chromic acid → Amanzi e-Ultrapure | Izikhathi ezingama-50 |
| Hdpe | I-Ethanol ultrasonic → ukomisa uNitrogen | Izikhathi ezingama-30 |
Khetha izindlela zokuhlanza ezifanele ngokususelwa ezintweni zokuqinisekisa ubumsulwa besampula.
Iphutha 3: Ukunganaki ukuhambisana kwamakhemikhali phakathi kwezinto ezibonakalayo kanye ne-reagents
Ukuqhathaniswa kokuvumelana:
| Uhlobo lwe-realent | Ekhanyayo | Hdpe | Thinta ngothando | I-PUT |
|---|---|---|---|---|
| Toluene \ xylene | ✓✓✓ | ✓✓ | ✗ | ✓✓✓ |
| I-acid enamandla (ph <2) | ✓✓✓ | ✗ | ✗ | ✓✓ |
| I-acetone | ✓✓ | ✓✓✓ | ✓✓ | ✓✓ |
Khetha izinto ze-vial ezihambelana ne-reagents yakho ukugwema ukusabela kwamakhemikhali okungathinta imiphumela yokuhlola.
Iphutha 4: Isitoreji esingalungile esiholela ekungcoleni ngokomzimba
Ukuqhathanisa amacala:
-
Isitoreji esiqondile se-VS.
-
Ukuvikelwa okunganele okunganele okubangela umsindo wangemuva we-fluorescent.
Isincomo: Khetha izinguqulo zengilazi zoqobo ezinsundu (vs2017b) noma ama-vials avikelekile akhanyayo ukuphatha amasampula abucayi.
Iphutha 5: IVoluvomu Emugqemeni Eqondile Okuholela Kumiphumela Eqedile
Idatha ebalulekile: Lapho ivolumu yangempela yokugcwalisa ye-20ml scintillation vial idlula i-18ml, ukusebenza kahle kwe-liquid scintillation counter kuncipha ngo-12-16%.
Izinga Lokusebenza: Sebenzisa inqubo yokumaka ehlombe ukuze uqinisekise ukuthi ivolumu yokugcwalisa ingaphakathi kobubanzi obunconyiwe.
3. Ukuqinisekiswa kokuhlola kanye nokusekelwa kwedatha yezobuchwepheshe
-
Ukuhlolwa kwangaphandle kukhombisa ukuthi ukusebenzisa kahle ama-CS222 CAPS ama-CS22 CAPS atholakale kahle ezintweni ze-Tritium -led aleveli ezinesilinganiso sokulahleka kokulondolozwa kwamaviki angaphansi kwama-0,5%, kuqhathaniswa ne-7.2% ngezigqoko ezijwayelekile.
-
Izinto ezibonakalayo ze-Glass vs2017 kukhombisa izinga lokuphuka kwe-zero ekuguqukeni kokushisa okusuka ku--196 ° C kuya ku-150 ° C. ° C.
