Kusankha pakati pa HPLC ndi UHPLC kumatha kukhudza kwambiri magwiridwe antchito a labotale yanu. Bukuli likufotokoza za kusiyana kwakukulu, ubwino, ndi kagwiritsidwe ntchito ka njira iliyonse - kuphatikiza upangiri wa akatswiri pazosankha zogwiritsidwa ntchito kuti asunge magwiridwe antchito apamwamba ndi zinthu za Aijiren za chromatography.

HPLC chitsanzo pretreatment ndi sitepe yovuta yomwe imatsimikizira kulondola ndi kudalirika kwa kusanthula kwa chromatographic. Bukuli la Aijiren limafotokoza gawo lililonse - kuyambira kusefera ndi kuchotsa mpaka kutulutsa - kuthandiza ma labotale kupeza zitsanzo zoyera, nsonga zakuthwa, komanso moyo wautali wa zida.

Kafukufuku wokhazikika amawunika momwe mankhwala, mamolekyu ang'onoang'ono achilengedwe, ndi mayankho azitsulo achitsulo amachitira zinthu ngati kutentha kwambiri, kuzizira, komanso kuwonetsa kuwala. Bukuli limayang'ana mwadongosolo makina monga oxidation, hydrolysis, isomerization, ice-crystal exclusion, and photodegradation, ndikuwunikanso njira zoyezera, kuphatikiza DSC, UV-Vis, DLS, ndi HPLC-MS-yopereka njira yolimba yopangira ma protocol oyeserera othamanga pazovuta zazikulu za chilengedwe.

Zosefera za syringe ndizofunikira zogwiritsidwa ntchito pokonzekera zitsanzo za HPLC, kuteteza mizati ndi zowunikira ku tinthu tating'onoting'ono ndi kuipitsidwa. Bukuli likufananiza makhalidwe a PTFE, Nylon, PVDF, ndi PC membrane zosefera-kukambilana zosungunulira zosungunulira, mitengo yothamanga, kumanga mapuloteni, zochotsamo ndi njira zogwiritsira ntchito bwino-kuti athandize ma laboratory kusankha nembanemba yoyenera kwambiri yodalirika komanso yobwerezabwereza kusanthula ntchito.

Mu ultra-trace analytical workflows, kutayika kwa adsorption pamtunda wa vial-chifukwa cha malo a silanol ndi zonyansa zachitsulo-kungathe kuwononga kwambiri kuchuluka kwake. Bukhuli likufotokoza njira za kutsatsa, kuyerekeza kutsekedwa, silanization, PEG, ndi PFDCS njira zokutira, ndikuwonetseratu deta yogwira ntchito-kuphatikizapo kuchira> 90-99% ya polar analytes m'mabotolo ochiritsidwa-kuthandiza ma laboratory kusankha mankhwala abwino kwambiri a vial pamwamba kuti apititse patsogolo kulondola ndi kubereka.

Nkhaniyi ikuwunikanso kagwiritsidwe ntchito ka EPA-certified 8-60mL VOA MV A mbale zopangidwa ndi galasi lapamwamba la TypeI borosilicate la volatile organic compound (VOC) posanthula zachilengedwe. Mitu ikuphatikizapo ndondomeko zoyendetsera zinthu (monga Method 5035), kasungidwe koyenera kachitsanzo, kayendetsedwe ka zinthu ndi kasungidwe, zotsatira za zinthu zotengera kukhazikika kwa zitsanzo, ndi kutsata malamulo—zonsezi n’cholinga choonetsetsa kuti mayendedwe angatsatike, osaonongeka poyang’anira chilengedwe.

Mass spectrometry ndi njira yowunikira yamphamvu yokhala ndi chidwi kwambiri komanso tsatanetsatane, yomwe imagwira ntchito yofunika kwambiri pakukula kwa mankhwala, bioanalysis, ndi kuwunika zachilengedwe. Nkhaniyi ikuyang'ana mfundo zake zofunika kwambiri, zatsopano zamakono zamakono, ndi machitidwe osinthika, ndikupereka chithunzithunzi chokwanira cha mass spectrometry.

Nkhaniyi ikufotokoza za kupatuka kounika komwe kumachitika chifukwa cha kulephera kusindikiza mu zitsanzo za VOC panthawi yoyesedwa, kusanthula zoperewera za mbale zachikhalidwe zowononga kapu, ndikupereka njira zothetsera kukhathamiritsa monga PTFE\/silicone composite gaskets ndi makapu oyendetsedwa ndi torque kuti apititse patsogolo kulondola kosanthula.

Mbale 20mL scintillation ndizofunikira pakuyesa kwa radioactive pamankhwala a nyukiliya, maphunziro a pharmacokinetic, ndi kuwunika kwachilengedwe. Nkhaniyi ikufotokoza zochitika zazikulu 8 zogwiritsira ntchito, komanso kufananitsa zinthu ndi njira zodzitetezera, kuthandiza ma labotale kukhathamiritsa chitetezo ndi kulondola kowunika.
