Ukukhetha ama-vials alungile ekhanda kubalulekile. Babalulekile emiphumeleni efanelekile nethembekile ye-GC. Ama-headspace vials acugela ukuthwebula kanye nokuhlaziya amakhompiyutha aguqukayo. Ukukhetha amalungelo kungathinta kakhulu ukuhlaziya kwakho. Nazi izinto ezibalulekile okufanele uzicabangele lapho ukhetha ama-headspace vials.
Impahla ye-vial
Izinto ezibonakalayo ze-vial zibalulekile. Izinto ezilungile zingavikela ubuqotho besampula yakho. Izinto ezivame kakhulu ziyingilazi nepulasitiki.
Izingilazi zeglasi
Ingilazi iyinto engcono kakhulu yezicelo eziningi. Inokumelana okukhulu kwamakhemikhali nokuvunza. Futhi ama-vials engilazi alungele amakhompiyutha amaningi aguqukayo nama-solvents. Abasabeli ngamakhemikhali amaningi, baqinisekisa ubuqotho besampula. Ama-Glass Vavials ajwayelekile ingilazi.
Ama-vials epulasitiki
Ama-vials epulasitiki ajwayelekile enziwe nge-polypropylene. Ayijwayelekile, kepha angasetshenziselwa izinhlelo ezithile. Zingabizi kakhulu futhi zilungele amasampula angaxhumana kahle nengilazi. Kodwa-ke, ama-vials epulasitiki anokumelana okushisayo okuphansi. Bavame ukufuya noma bamukele amakhompiyutha athile. Ngakho-ke, azilungele izivivinyo ezithile.
Usayizi we-vial
Ama-headspace vials anobukhulu obuhlukile. Okuvame kakhulu 10 ml no-20 ml. Usayizi owukhethayo uncike kuvolumu yakho yesampula. Kufanele futhi ihlangabezane nezidingo zokuhlaziywa kwakho.
Lokhu kufanelekile kumanani amancane wesampula. Zivame ukusetshenziswa namasampula akhawulelwe. Ziyasetshenziswa futhi lapho sidinga ukuhlaziya okuphezulu. Ama-vials amancane anganciphisa futhi i-solvent edingekayo ukuze ihlaziywe. Lokhu kuyasiza lapho kusebenza ngamakhemikhali abizayo noma anobungozi.
Lawa amasayizi ajwayelekile ezicelo eziningi ze-GC. Bahlalisa amavolumu amakhulu wesampula, okwenza balungele ukuhlaziya okujwayelekile. Ama-vials amakhulu anesikhala esithe xaxa. Lokhu kuhle ukuhlola amakhompiyutha aguqukayo. Lokhu kuvumela ukulinganisela okungcono kanye nezilinganiso ezinembile ngokwengeziwe.
Ukwakheka kwe-vial
Ukwakheka kwe-vial kungathinta nokusebenza kahle kokuhlaziywa kwakho. Ama-headspace vials atholakala ngokuvamile ngezimo ezimbili: phansi-phansi kanye nokungaphansi komjikelezo.
Ama-vials aphansi aphansi
Lawa ma-vials ahlala kakhulu ku-autosampler futhi mancane amathuba okuthi amathiphu. Zilungele ukusetshenziswa ezinhlelweni ezenzakalelayo. Ama-vials aphansi aphansi kulula ukuphatha. Futhi mancane amathuba okugoqa. Lokhu kungasiza ema-labs angena phezulu.
Ama-vials aphansi
Zingasetshenziswa ngamanye ama-autosamplers. Zingakhethwa kwezinye izimo. Bavumela ukululama okuphelele kwesampula, ukunciphisa imfucuza yesampula. Ama-vials angezansi aphansi ajwayele ukusetshenziswa emisebenzini yezandla. Baphinde basetshenziswe ngama-autosamplers athile adinga lesi simo.
Cap and septhembaa
I-cap ne-SEPTA kubalulekile ukuze kugcinwe ubuqotho besampula yakho. Baqinisekisa ukuthi i-vial ihlala ivaliwe nokuthi azikho amakhompiyutha ashubile aphunyuke.
Iziqeshana
Ama-CAPS eza ngezinto ezahlukahlukene, njenge-aluminium nama-magnetic cap. Amakhabethe kazibuthe asetshenziswa kuma-autosamplers awadingayo. I-cap kumele ilizwe ngokuqinile. Lokhu kuvimba ukulahleka kwamakhompiyutha aguqukayo nokungcoliswa kwemvelo.
Upende
I-SEPTA iyingxenye ye-cap ebhobozwe yinaliti yesirinji ukuze ikhiphe isampula. Sebenzisa i-Septa ephezulu. Zenziwe ngezinto ezifana ne-PTFE \
silicone. Kunconywa ngoba zinikeza uphawu oluqinile futhi zivikele ukungcoliswa. I-Septa kufanele ihlale isikhathi eside. Kufanele ikwazi ukubekezelela imijovo eminingi ngaphandle kokuphula uphawu.
Ukuhambisana ne-autosampler
Qinisekisa ukuthi ama-headpace vials owakhethayo ahambisana ne-autosampler yakho. Amanye ama-autosamplers angadinga osayizi abathile be-vial, bobunjwa, kanye nezinhlobo ze-cap. Khulumela incwajana yakho ye-autosampler. Bheka incwajana yakho ye-autosampler.
Ukufaneleka kwamakhemikhali
Cabanga Ngezakhiwo Zasezampula Zakho. Cabanga ngokuthi baxhumana kanjani nezinto ezibonakalayo ne-Septa. Isibonelo, ama-solvent athile angasabela ngama-vials epulasitiki noma anciphise i-silicone Septa. Njalo khetha izinto zokwakha. Kufanele zihambisane nesampula yakho. Lokhu ukugwema ukungcoliswa noma ukucekelwa phansi. Ukuvumelana kwamakhemikhali kubalulekile. Ukungalingani kuvimbela ukulahleka kwesampula, ukonakala, noma ukungcoliswa. Lezi zinkinga zingalimaza ukunemba kwemiphumela yakho.
Ukuvumelana kwe-Batch
Sebenzisa ama-vials nama-cap afanayo kuwo wonke amabhethri. Lokhu kubalulekile emiphumeleni enembile nezezimali. Ukuhlukahluka ngobukhulu be-vial noma ikhwalithi ye-septa kungaholela emiphumeleni engahambisani. Abahlinzeki kufanele babe nezindinganiso ezisezingeni eliphakeme zokukhiqiza. Futhi baziwa nge-batch-to-batch ukuvumelana. Lo mhlinzeki ungaba ukukhetha kwakho kokuqala. Iziqinisekiso ezingaguquki ziqinisekisa ukuthi ukuhlaziya kwakho kuhlala kuthembekile futhi kuzakhiwe kabusha ngokuhamba kwesikhathi.
Ukwethembeka Kwe-Supply Chain
Ukuhlaziywa kwe-HPLC kuvame ukudinga okutholakalayo. Lokhu kufaka phakathi ama-vials, ama-cap, ne-pepta. Hlaziya ukuphathwa kokusungula komhlinzeki, izinqubo zokugcwalisa i-oda, kanye nokwethenjwa kwethempeli. Ingabe zinikeza imikhiqizo ngesikhathi ukuvimbela ukubambezeleka kokuhamba komsebenzi? Cabanga ngezinto ezinjengezikhathi eziholayo. Futhi, cabanga ngokunemba oku-oda nekhono labo lokuphatha ama-rush noma ama-oda wangokwezifiso. Umphakeli omuhle uzoba nenethiwekhi eqinile yokusatshalaliswa. Bazoba nezinto eziguqukayo. Lokhu ukuqinisekisa ukuthi uthola okudla kwakho kwe-HPLC ngesikhathi, ngaso sonke isikhathi.
Ukulawulwa kwekhwalithi nokuhambisana nokulawula
I-HPLC ivamile kwizimboni ezilawulwayo. Lokhu kufaka phakathi amakhemisi, ukudla, kanye nokuhlolwa kwemvelo. Ubuqotho bedatha nokuhambisana kubalulekile kulezi zimboni. Qiniseka ukuthi umphakeli unezilawuli ezisezingeni eliphakeme. Kufanele babe nesitifiketi se-iso, ukuhlolwa okuningi kakhulu, kanye nemibhalo yokulawula. Lokhu kukunika ukuzethemba. Imikhiqizo yabo izohlangabezana nezinga eliqinile kanye namazinga alawulayo. Lokhu kuvikela ubuqotho bemiphumela yakho yokuhlola. Funa abahlinzeki abanganikeza izitifiketi zokuhlaziywa. Kufanele futhi banikeze ukwesekwa kokuqinisekiswa kwendlela kanye neminye imibhalo yokuqinisekisa ikhwalithi. Le mibhalo ikhombisa ukuzibophezela kwayo kwikhwalithi yomkhiqizo nokulandela umthetho.
Izinsizakalo ezingezwe nge-Value
Ikhwalithi yomkhiqizo kanye nokwethenjwa kubalulekile. Kepha umphakeli omuhle we-HPLC we-vial kufanele futhi anikeze izinsizakalo ezingeziwe. Lezi zinsizakalo zithuthukisa ukuhlaziywa kwakho. Funa abahlinzeki abangasenza ngokwezifiso imikhiqizo kwizidingo zakho. Kufanele banikeze izeluleko zokuthuthuka kwezeluleko zochwepheshe. Futhi izinhlelo ezigcwele zokulawulwa komthengisi nazo zinikeziwe. Lokhu okungeziwe kungenza umsebenzi wakho ube lula. Bazothuthukisa umkhiqizo. Bazothuthukisa futhi ukubuyiselwa kwemali ekutshalweni kwemali kwakho kuzinto ze-HPLC. Isibonelo, abanye abahlinzeki bangenza osayizi be-vial ngokwezifiso. Futhi bangenza amantamo wangokwezifiso, ukuphrinta, nezinye izici ngokuya ngezidingo zakho. Abanye bangaba nososayensi besicelo sendlu. Bangasiza ngokuthuthuka kwendlela noma ukuxazulula inkinga.
Ukugcina
Ukukhetha ama-headpace vials afanelekile. Bahle kakhulu ukuthola imiphumela efanelekile nethembekile yegesi ye-chromatography. Cabanga ngezinto ezifana nezinto ezibonakalayo, usayizi, nokwakheka. Futhi, ikhwalithi ye-cap ne-septum, kanye nokuhambisana kwe-autosampler. Ungakhohlwa ukuhambisana kwamakhemikhali, ukuguquguquka kwe-batch, kanye nokwethenjwa kokwethenjwa. Futhi, cabanga ngokulawulwa kwekhwalithi, ukuhambisana nokulawula, kanye nanoma yiziphi izinsizakalo ezingeziwe. Kufanele uhlole ngokucophelela lezi zinto. Ngemuva kwalokho uzokhetha izipesheli ezinhle kakhulu zezidingo zakho. Bazoqinisekisa imiphumela eqondile futhi ephindaphindwayo ekuhlaziyweni kwakho kwe-GC. Ungathemba umphakeli ukuhlinzeka ngemikhiqizo esezingeni eliphakeme. Banobungcweti, amaketanga athembekile athembekile, kanye nezixazululo ezintsha. Bazosiza ilebhu yakho iphumelele.
