Scagairí steallaireis uirlis riachtanach iad i dtimpeallacht na saotharlainne, go háirithe le haghaidh ullmhú samplach sa cheimic anailíseach. Tá siad deartha chun cáithníní agus ábhar salaithe a bhaint as leachtanna sula ndéantar anailís orthu, ag cinntiú íonacht agus sláine samplach. As na roghanna éagsúla atá ar fáil, is iad 0.45 µm agus 0.22 µm scagairí steallaire dhá cheann de na cineálacha is coitianta a úsáidtear. Tá tuiscint ar na difríochtaí idir na scagairí seo, a n -iarratais, agus conas an scagaire ceart a roghnú do do riachtanais shonracha riachtanach chun torthaí cruinne agus iontaofa a bhaint amach.

Is éard atá i scagairí steallaire ná scagaire membrane atá clúdaithe i bplaisteach nó i dtithíocht ghloine a scaipeann méideanna beaga leacht go héifeachtach. Cinneann méid pore an scagaire méid na gcáithníní is féidir a bhaint. Is iad an dá mhéideanna pore is coitianta ná 0.45 µm agus 0.22 µm, a bhfuil úsáidí difriúla ag gach ceann acu ag brath ar riachtanais anailíseacha.

Scagairí steallaire 0.45 µm

Iarratais:

Scagairí steallaire 0.45 µmis iondúil go n -úsáidtear iad le haghaidh scagacháin ghinearálta agus deireadh a chur le cáithníní. Tá siad éifeachtach maidir le cáithníní níos mó a bhaint agus úsáidtear iad go coitianta sna hiarratais seo a leanas:

Réiteach: Is minic a úsáidtear scagairí 0.45 µm mar réamhíocadóirí chun ionstraimíocht iartheachtach níos íogaire (mar shampla córais HPLC nó GC) a chosaint ó cháithníní níos mó.

Soiléiriú: Tá na scagairí seo oiriúnach chun réitigh a shoiléiriú, go háirithe i ngnáthnósanna imeachta saotharlainne nuair nach cúis mhór imní é éilliú miocróbach.

Scagachán Céim Soghluaiste: I bhfeidhmchláir chrómatagrafaíochta, úsáidtear scagairí 0.45 µm chun an chéim shoghluaiste a scagadh chun éilliú colún a chosc.

Teorainneacha:

Cé go n -úsáidtear scagairí 0.45 µm go forleathan, b'fhéidir nach mbeadh siad leordhóthanach d'iarratais a dteastaíonn steiriliú nó deireadh le miocrorgánaigh níos lú. Is féidir leo cáithníní atá níos mó ná 0.45 µm a scagadh go héifeachtach, ach d'fhéadfadh siad ligean do bhaictéir níos lú dul tríd, as a dtiocfaidh éilliú i dturgnaimh íogaire.

Scagairí steallaire 0.22 µm

Iarratais:

Scagairí steallaire 0.22 µmIs minic a thugtar scagairí grád steiriliú orthu go minic. Tá siad deartha chun baictéir agus miocrorgánaigh eile a bhaint as réitigh, rud a fhágann go bhfuil siad oiriúnach do na hiarratais seo a leanas:

Steiriliú: Is minic a úsáidtear na scagairí seo in iarratais mhicribhitheolaíocha chun meáin chultúir, maoláin, agus réitigh eile a steiriliú a dteastaíonn timpeallacht steiriúil uathu.

Foirmlithe Cógaisíochta: Sa Tionscal Cógaisíochta, baintear úsáid as scagairí 0.22 µm chun a chinntiú go bhfuil réitigh insteallta saor ó éilliú miocróbach.

Biteicneolaíocht: Tá siad riachtanach i bpróisis bhiteicneolaíochta ina gcaithfear sláine na samplaí bitheolaíocha a choinneáil, mar shampla in iarratais ar chultúr na gceall.

Teorainneacha:

Cé go bhfuil scagairí 0.22 µm éifeachtach chun baictéir a bhaint, b'fhéidir nach mbeidh siad riachtanach do gach iarratas. Maidir le gnáth -scagachán nuair nach ábhar imní é éilliú miocróbach, d'fhéadfadh costas neamhriachtanach a bheith ag baint úsáide as scagaire 0.22 µm.

Conas an scagaire steallaire ceart a roghnú

Braitheann roghnú an scagaire steallaire cheart ar roinnt fachtóirí, lena n -áirítear nádúr do shamplaí, an leibhéal scagacháin a theastaíonn, agus an t -iarratas atá beartaithe. Seo roinnt cúinsí chun cabhrú leat an rogha ceart a dhéanamh:

Socraigh an cuspóir: Má éilíonn d'iarratas steiriliú nó baint baictéarach, roghnaigh scagaire steallaire 0.22 µm. Maidir le riachtanais scagacháin ghinearálta, amhail tuaslagán a shoiléiriú nó ionstraim a chosaint, d'fhéadfadh sé go mbeadh scagaire 0.45 µm leordhóthanach.

Smaoinigh ar thréithe samplacha: Déan measúnú ar airíonna an tsampla atá á scagadh. Mar shampla, má tá cáithníní níos mó sa sampla, d'fhéadfadh scagaire 0.45 µm a bheith níos éifeachtaí. Os a choinne sin, má tá an sampla íogair maidir le héilliú miocróbach, moltar scagaire 0.22 µm.

Déan meastóireacht ar chostas agus ar bhuiséad: Smaoinigh ar bhuiséad do shaotharlainne. Cé go bhfuil scagairí 0.22 µm níos costasaí i gcoitinne, d'fhéadfadh siad a bheith riachtanach le haghaidh feidhmchlár sonrach. Costas cothromaíochta leis an tábhacht a bhaineann le sláine agus cruinneas samplach.

Téigh i gcomhairle le treoirlínte an déantóra: Déan tagairt i gcónaí do shonraíochtaí agus do mholtaí an déantóra don scagaire steallaire sonrach atá á mbreithniú agat. Is minic a sholáthraíonn siad faisnéis luachmhar faoi na hiarratais agus na teorainneacha atá beartaithe dá gcuid táirgí.

Bailíochtú modh a dhéanamh: Mura bhfuil tú cinnte cén scagaire atá le húsáid, smaoinigh ar thurgnamh bailíochtaithe modh a dhéanamh chun feidhmíocht an dá chineál scagtha a chur i gcomparáid le d'iarratas ar leith. Is féidir leis seo cabhrú leat a chinneadh cé na scagaire a sholáthraíonn na torthaí is fearr.

Tá tuiscint ar na difríochtaí idir an dá chineál scagtha seo, a n -iarratais, agus conas an scagaire ceart a roghnú do do riachtanais shonracha riachtanach chun torthaí cruinne agus inatáirgthe a bhaint amach i suíomh saotharlainne. Trí chuspóir an scagacháin, na saintréithe samplacha, na dtreoirlínte costais agus an déantóra a bhreithniú, is féidir leat cinneadh eolasach a dhéanamh a fheabhsóidh éifeachtúlacht agus éifeachtúlacht do phróisis anailíse.
