Isampulu yamalungiselelo kunye nohluzo lwefom yokuqala yokhuselo lwechromatography. Olu ngeno luqhekeza iindlela ezintathu zokungaphumeleli-ungcoliseko kunye nokuphazamiseka kwe-matrix, ukuvala isihluzo, ukuchasana kwe-solvent-membrane-kwaye unikezela ngamanyathelo abambekayo ngaphakathi kwesakhelo soKhuselo-Ukubeka iliso-uLungiso lokuphelisa ukukhukuliseka kwesiseko, ukugqwetheka okuphezulu, kunye nokuvalwa kwekholamu.

Olu xwebhu luchaza isiganeko songcoliseko kwi-European TOP5 pharma: I-LC-MS ifumene amaqhekeza e-PTFE (m\/z 412.96). Ukusekwa kwemodeli ye-torque-particle-column esebenzayo. Inkqubo yetorque ekrelekrele (±0.05Nm) iphucule izinga lokupasa kweebhetshi ukusuka kuma-84.3% ukuya kuma-99.6%.

Ukukhetha i-vial yesampuli efanelekileyo kwi-chromatographic workflows ichaphazela ngokuthe ngqo ukuchaneka kwedatha kunye nokuveliswa kwakhona. Eli nqaku liphonononga iiyantlukwano eziphambili phakathi kwe-HPLC kunye ne-GC ye-vials-egubungela iimeko zesicelo, izinto eziphathekayo \/impawu zokuyila, iindlela zokutywina, kunye nokuhambelana kwesixhobo. Ikwabonelela ngeengcebiso zokuthenga kunye ne-FAQ ukunceda abahlalutyi balebhu, amaqela e-R&D amayeza, kunye neelebhu zovavanyo lomntu wesithathu ukwenza izigqibo ezinolwazi kunye nokunyusa ukusebenza kakuhle.

Eli nqaku libanzi lichaza ukuba kutheni i-TOC Organic (itotali ye-organic organic carbon) ibalulekile umgangatho wamanzi parameter kwiilebhu kunye nezityalo zonyango. Sithelekisa i-TOC kunye ne-COD, i-BOD kunye ne-DOC, ukuphonononga iindlela zokuhlalutya kwe-TOC (ukutsha, i-UV / persulfate, njl.) kunye netafile yesigqibo, kwaye igxininise izicelo ze-TOC kwimeko yendalo, amayeza kunye ne-industrial setting. Sigubungela ezona zenzo zilungileyo zesampulu, izinto ezintsha zamva nje (abahlalutyi abaqhagamshelwe yi-IoT, izinzwa eziphathwayo, izixhobo zedatha ye-AI) kunye neendlela ezizayo, eziphela ngokubizelwa kwisenzo esisebenzayo kwiilebhu zamanzi kunye nezityalo.

Ukugqiba phakathi kwe-HPLC kunye ne-GC ayibobuchule kuphela-lukhetho olubalulekileyo oluchaphazela ukuthembeka kwedatha yelebhu yakho kunye nohlahlo lwabiwo-mali. Ngokusekwe kwiminyaka yamava ebhentshi, esi sikhokelo sinqumla ithiyori ukukubonisa indlela ukuguquguquka kwemolekyuli kunye nokuzinza kwe-thermal kuyalela ukuhamba kwakho komsebenzi. Sikwantywila kwimpembelelo "efihlakeleyo" yezinto ezityiwayo ezifana nesepta kunye netywina kwiziphumo zakho.

Ukusuka kumanzi ane-asidi enamandla ukuya kumachiza e-lipophilic, ukukhetha i-vial yesampulu engalunganga kunokuphazamisa ukubuyiswa okanye kubangele iincopho ze-phantom. Esi sikhokelo sichitha imida yokusebenza kwe-soda-lime vs. iglasi ye-borosilicate kwaye inikezela ngezicwangciso ze-vial kunye ne-septa ezithatha uhlalutyo lomkhondo ukuya kwiimvavanyo zesiqhelo-ukuphelisa ukusebenza ngokutsha okubangelwa ukungahambi kakuhle kwezinto.

Eli phepha lichaza iinkcukacha ze-Aijiren's ISO 965\/GOST-R ezihambelanayo ne-septa edibeneyo yokuvavanya ukutsalwa kwamandla, idatha yokuqinisekisa ngokugqithisileyo, kunye nezicwangciso zedijithali ze-QA, ukuveza ikhonkco phakathi kokuchaneka kwentambo kunye nokunyaniseka kwetywina kwizinto ezisetyenziswa kwilebhu.

Phonononga iiyantlukwano ezibalulekileyo phakathi kwe-GC-MS kunye ne-GC-MS\/MS kwesi sikhokelo sibanzi. Thelekisa iindlela zabo, ukusebenza, iindleko, kunye neemeko ezifanelekileyo zokusetyenziswa-ezilungele iilebhu ezifuna uhlalutyo oluchanekileyo lokulandelela kwiisampuli ezinzima.

Lawula ukufuduka ukusuka kwi-HPLC ukuya kwi-LC-MS. Isikhokelo sethu sobuchwephesha sibandakanya uzinzo lomthombo we-ion, ukuphazamiseka kwe-sodium adduct, kunye nophuculo oluyimfuneko lokuhlalutya umkhondo.
