20ml Scintillation vials Kushandisa Runyorwa: 5 Zvakajairika Kuedza Kukanganisa uye Mhinduro
Chinyorwa ichi chinovavarira kubatsira vaongorori vekuramba vachiona uye kururamisa zvikanganiso zvishanu zvinowanzoitika zvine chekuita nekushandiswa kwe20ml scintillation vialaactive sampula.
Zvishoma zvisirizvo, sekusimbisa zvisina kufanira kana kuchenesa zvisina kukodzera, zvinogona kutungamira mukutsauka kwakakosha kwedata, nezvidzidzo zvinoratidza kusiyanisa makumi matatu muzana mumhedzisiro.
Chinyorwa ichi chinobva chave nyaya sekusimbisa zvisina kufanira, kusimbiswa kwevasina kuchena, kuregeredza makemikari kuwirirana pakati pezvisikwa uye kudzosera zvinhu zvekusvibisa kusvibiswa, uye vhoriyamu zvisizvo zvinokonzeresa mhedzisiro.
Nekupa zvakadzama mhinduro uye yekuyedza data yechokwadi, chinyorwa chinotungamira vaongorori mukugadzirisa maitiro avo ekuedza kuti ave nechokwadi chekururamisa kwedata uye kuvimbika.
1. Nhanganyaya: Kukanganisa kudiki, mikuru migumisiro
Mune radioctive sampule kuongorora, zvidiki zvisirizvo zve20ml scintillation vials inogona kutungamira kutsauka kwedata kusvika ku30%, nevazhinji vanotsvaga vasingazive nezvezvinhu zvepasi.
Sekureva kwedata kubva kune vekunze vanobva kuThomas vesainzi, kushandisa zvisina kunaka kweScintillation vigial anokaunti kusvika 17% yekuedza kudzokorora mitengo.
2. Zvikanganiso zvishanu zvakajairika uye mhinduro dzadzo
ERROR 1: Kusina kusimba kushaikwa kunotungamira kune sampulizlization
Zvakafanana mamiriro ezvinhu: Kungotenderera cap ne1 \ / 4 tendeuka, kutadza kuzadzisa iyo CS22 cap Dhizaini ye3 \ / 4 inoshandura kuiswa chiyero.
-
Yakakwidziridzwa Background kukosha mu β-ray kuona.
-
Yakakanganiswa kuverenga mitengo mune yakaderera-zviitiko samples.
Solution: Ita shuwa iyo cap yakasimbiswa kune iyo dhizaini mwero, uchishandisa caps nePolyethylene cone liners kuti uwedzere kusimbisa kutendeka.
Kukanganisa 2: kushandisa vials pasina kunyatsochenesa
Njodzi Dzakasara: Toluene-based Scintillation Liquly inosara inogona kuyambuka-inosvibisa ne-soluble reagents.
Kuchenesa Kurudziro:
| Zvinhu | Yakakurudzirwa Kuchenesa Mumiriri | Maximum Reuse Times |
|---|---|---|
| Girazi (vs2017) | Chromic acid ged gage → Urefu mvura | 50 times |
| HDPE | Ethanol ultrasonic → nitrogen kuomesa | 30 times |
Sarudza nzira dzakakodzera dzekuchenesa dzinoenderana nezvinhu kuitira kuti uve nechokwadi chekufungidzira.
ERROR 3: Kuregeredza makemikari kuenderana pakati peVial zvinyorwa uye reagents
Kuenzanisa Kuenzanisa:
| Reagent Type | Girazi | HDPE | Pet | PP |
|---|---|---|---|---|
| Toluene \ / xylene | ✓✓✓ | ✓✓ | ✗ | ✓✓✓ |
| Yakasimba acid (pH <2) | ✓✓✓ | ✗ | ✗ | ✓✓ |
| Acetone | ✓✓ | ✓✓✓ | ✓✓ | ✓✓ |
Sarudza Vial zvinhu zvinoenderana neako reagents kuti udzivise makemikari maitiro anogona kukanganisa mibairo yekuedza.
ERROR 4: Kuchengetedza zvisina kunaka kunotungamira mukusvibiswa kwemuviri
Mhosva yekuenzanisa:
-
Yakarurama kuchengetedza vs. yakatwasuka yekuchengetedza inotungamira kuchema pamuromo wepinic.
-
Isina kukwana chiedza chengetedzo ichikonzera fluorescent background ruzha.
Kurudziro: Sarudza yekutanga brown vhezheni vhezheni (vs2017b) kana HDPE VAKAWANDA-Divhenekeri Vials Kubata Chiedza Chemumoyo Sampuli.
ERROR 5: Vhoriyamu Misjudgment inotungamira kuRubatsiro Mhedzisiro
Key data: Kana iyo chaiyo ichizadza vhoriyamu ye20ml scintillation vial inodarika 18ml, kugona kwekuona kweiyo iyo yemvura yeScintillation counter ne 12-15%.
Operation Makero: Shandisa mafudzi ekutarisa maitiro ekutonga kuti vhoriyamu inozadza iri mukati meiyo yakakurudzirwa.
3. Kuedza kusimbisa uye technical data rutsigiro
-
Yetatu-bato muedzo unoratidza kuti kushandisa zvakanyatsonaka CS222 caps-labeled zvinhu zvine huwandu hwekurasikirwa kwekurasikirwa pane zvishoma nezvishoma
-
Girazi zvinyorwa vs2017 inoratidza zero zero zero muedzo wekupisa muedzo wekupisa kubva -196
