02 Ntụle vials okpu Ntuziaka
Enwere ụdị mkpuchi vial atọ: okpu crimp, okpu snap na okpu skru.Usoro akara ọ bụla nwere uru nke ya.
okpu crimp: Okpu mwekota na-amanye septa n'etiti vials nsọtụ nke ihe nlele iko na okpu aluminum apịaji.Mmetụta akara dị ezigbo mma, nke nwere ike igbochi evaporation sample nke ọma.Ọnọdụ nke septum na-anọgide na-agbanwe agbanwe mgbe a na-agbanye ihe nlele ahụ site na injector akpaka.Ọ dị mkpa iji crimper mechie vials sample.Maka obere ihe nlele, crimper akwụkwọ ntuziaka bụ nhọrọ kacha mma.Maka ọnụ ọgụgụ dị ukwuu nke ihe nlele, enwere ike iji crimper akpaka.
okpu snap: Okpu snap bụ ndọtị nke ọnọdụ akara nke mkpuchi mkpọ.Okpu plastik dị na nsọtụ nke vials sample na-etolite akara site na ịpịnye septa n'etiti iko na okpu plastik gbatịrị agbatị.Esemokwu dị na mkpuchi plastik bụ n'ihi mbọ ya iji weghachi nha mbụ ya.Esemokwu ahụ na-etolite akara n'etiti iko, okpu na septa.Enwere ike mechie mkpuchi mkpuchi plastik na-enweghị ngwá ọrụ ọ bụla. Mmetụta mkpuchi nke mkpuchi mkpuchi adịghị mma dị ka ụzọ abụọ ndị ọzọ na-ekpuchi ya. Ọ bụrụ na ọ tọhapụrụ oke, mmetụta mkpuchi ahụ ga-adị njọ, na septa nwere ike ịhapụ ọnọdụ mbụ ya.
Okpu mkpuchi: Okpu mkpuchi bụ ihe zuru ụwa ọnụ.Ịmechi okpu ahụ na-arụ ọrụ ike nke na-amanye septa n'etiti rim iko na okpu aluminom.N'ime usoro ntinye ihe nlele, mmetụta mkpuchi nke mkpuchi mkpuchi ahụ dị oke mma, a na-ejikwa gasket na-akwado ya site na igwe.Enweghị ngwaọrụ achọrọ maka mgbakọ.
A na-edozi PTFE / silicone septa nke okpu ịghasa na okpu polypropylene site na usoro njikọ na-abụghị ihe mgbaze.Emebere teknụzụ njikọ iji hụ na septa na okpu na-anọkọ ọnụ mgbe niile n'oge njem yana mgbe etinye okpu na vials sample.Adhesion a na-enyere aka igbochi septa ka ọ ghara ịdaba ma gbanwee mgbe a na-eji ya eme ihe, mana isi akara ka bụ ike arụ ọrụ a na-etinye mgbe a na-agbanye okpu ahụ na vial sample.
Usoro nke ịgbachi okpu bụ ịmepụta akara ma debe septa n'ọnọdụ ziri ezi n'oge ntinye nke nyocha.Ọ dịghị mkpa ịkwanye okpu ahụ nke ọma, ma ọ bụghị ya, ọ ga-emetụta akara ahụ ma mee ka septa daa na transpose.Ọ bụrụ na akpọchie okpu ahụ nke ọma, septa ga-ekpu ma ọ bụ gbajie.

Ụdị m, iko 50 ahịrị-mgbapụ: Ọ bụ alkaline karịa 33 akara mmefu ego na enwere ike iji ya na ngwa ụlọ nyocha dị iche iche.Ọnụego mgbasawanye ya dị ihe dịka 50x 10 ^ (- 7) ℃, nke bụ silicon na oxygen mejupụtara, ma nweekwa obere boron.A na-eme ọtụtụ vial Hamag amber site na iko mgbasawanye 50.
Ụdị nke m, iko 70-akara-ego: Ọ bụ ihe aku na uba karịa 50 akara mmefu ego na enwere ike iji ya na ngwa ụlọ nyocha dị iche iche.Ọnụego mgbasawanye ya dị ihe dịka 70x 10 ^ (- 7) ℃, nke bụ silicon na oxygen mejupụtara, ma nweekwa obere ego boron.A na-eme nnukwu vial Hamag dị ukwuu site na iko mgbasawanye 70.
Iko a na-arụ ọrụ (DV): Maka ndị nyocha nwere polarity siri ike na ijikọ n'elu iko pola nke iko ahụ, nkwụsị nke vial sample nwere ike ịbụ ezigbo nhọrọ.Emepụtara elu enyo hydrophobic site na ọgwụgwọ silane na-emeghachi omume na oge iko.Enwere ike ịkpọọ vial sample agbanyụrụ ma chekwaa ya ruo mgbe ebighị ebi.
Polypropylene plastics: Polypropylene (PP) bụ plastik na-adịghị arụ ọrụ nke enwere ike iji ebe iko na-adabaghị adaba.Ihe nlele polypropylene ka nwere ike idowe akara nke ọma mgbe a na-agba ya ọkụ, si otú a na-ebelata ohere nke ikpughe na ihe ndị nwere ike ime.Okpomọkụ kachasị arụ ọrụ bụ 135 ℃.
