I. YEMAHARA YEMAHARA KUKOSHESA ZVINOKOSHA ZVAKANAKA

Kugumira kwetsika yechinyakare mango

Standard screw-cap vials vimba nekunyanyisa kusimbisa, zvichikonzera kudzvinyirirwa kusingaenzaniswi. Tembiricha yekudziya inogona kukonzera kuwedzera kwekuwedzera uye zvinopesana, zvichitungamira kune micro gasi kubiwa.

Njodzi dzakawanda dze-low-point-point vocs

Low-Boling-Point Compounds seBenzene Deativatives (Boiling Point <150 ° C) Kunokurumidza Kukora Pamhepo tembiricha. Kana iyo Vial's Isiratidzo Gasket ine yakakwirira adsorption kana kuramba makemikari kurwisa, kurasikirwa kwemuenzaniso kunowedzera, kunogona kuderedza mari yekudzorera ne30%.

Kuyambuka-kusvibiswa uye kuongororwa zvikanganiso

Kukundikana Kukundikana kwete kungoita kuti kurasikirwa nekurasikirwa kwekuongororwa asi kunogona kusumawo zvekunze zvinosvibisa. Semuenzaniso, vibrations panguva yekufambisa inogona kusunungura vial caps, inotungamira kuyambuka-kusvibiswa pakati pemasampula emisangano uye kukanganisa GC-ms fungidziro yeGC.

Ii. Matatu ehunyanzvi ekugadzirisa kwekugadzirisa chisimbiso

Mhinduro 1:Pre-Slit PTFE \ / Silicone Composite Septa
Zvinyorwa zvehunyanzvi:
PTFE (PolytetraFluoroHeryle) inopa yakasimba chemikoni yako inerness, kudzivirira vocs adsorption.
Iyo silicone layer inopa elastic cushioning, inogara tembiricha misiyano.

Pre-slit dhizaini inoderedza njodzi yekuburitsa kuturika panguva yesaiti yekupinda.

Unoda kuziva kuti ungasarudza sei Septa pre slit kana kwete?Dzvanya Pano kuti uzive

Mashandiro anoshanda: Vocs ongororo sePepa 8260, HJ 644-2013, uye zviyero zvakafanana.

Solution 2: Torque-inodzora capers

Core kukosha:
- Chaizvoizvo kudzora kudzora kusimbisa kudzvinyirira (yakakurudzirwa torque: 10-15 inch-mapaundi), kudzivisa kusapindirana kubva mukunyomba.
- Inosimbisa yunifomu yekubata pakati pe cap uye gasket, kudzivirira kubhururuka panguva yekuchengetedza kwenguva refu.

Mhinduro 3:Mirimo yemuenzaniso inoenderana neEPA 8260 zviyero

Sarudzo dzekusarudza:
- Kukwirira kwepamusoro mumuromo wemuromo wemuromo (i.e.,40ml yakafara-muromo).
- Zvinyorwa zvegirazi zvinofanirwa kunge zviri acid naAlkali-vanodzivirira nekuwedzera kwakasimba.
- Inoperekedzwa neSectified Septa, inosimbiswa kuburikidza nekureba kwekuedza.

III. Nyaya Yekudzidza: Kuipa kwekuisa chisimbiso yekufungidzira pakuongorora kwekuongorora

Iyo yekuedza yemamiriro ekunze yerabhoritari yakafananidza kuita pakati peiyo standard screw-cap vials uye yakagadziriswa inosimbisa mhinduro mhinduro:

Ongororo Metric	Standard screw-cap vials	Ptfe \ / silicone Septa + torque parapper
Benzive Kudzorera Rate	68%	98%
Xylene RSD (%)	15.2	4.7
Post-Transport Yakakura Rate	22%	0%

Chidzidzo chacho chakaratidza kuti kusimbisa kweSeposita Secalaling Soliding zvakanyanya kuvandudza kugadzikana kweiyo lows (<1PPB) ISOE \ / / I IEC 17025 Certification zvinodiwa.

Iv. Mhedziso uye Kurudziro

Kukundikana Kukundikana muVoMCS Sampuli hazvisi zvidiki - ivo vanokanganisa zvakananga kusanzwisisika uye kutendeka kwesainzi kwezvirevo zvekuongorora. Laboratorie inofanira:

Kutungamira kwakadzika-kusimbisa zvinokatyamara: Sarudza Pre-Certified PTFE \ / Silicone Septa uye yakakura-mouth sampuli vials.
Gadzirira Solaling Productionures: Shandisa Culque-inodzora capers uye anogara achiisa mari yekumanikidzwa.
Simbisa Mhando Dzekutonga: Monitor inosimbisa basa kuburikidza nekupfava kupora kuedza uye kutsiva akwegura sepsa nekukurumidza.

Ramangwana Outlook: Nekuwedzera kwehunyanzvi seEPA nzira kune-17 yekuteedzera voccs, iyo yakangwara inosimbisa masisitimu ekugadzirisa uye zvizere masangano ekugadzira anozova maindasitiri etsva.
