Is UHPLC always better than HPLC?

UHPLC offers higher resolution and faster analysis, but it comes with greater cost and stricter requirements—so “better” depends on your specific application.

Can I use the same columns for HPLC and UHPLC?

Typically not. UHPLC columns are optimized for higher pressure and smaller particles, and standard HPLC columns may not perform optimally or safely in UHPLC systems.

What key consumables should I upgrade for UHPLC?

Focus on low-adsorption vials, ultra-clean filters and injection systems with minimal dead volume, to maintain peak shape and reproducibility in UHPLC.

HPLC oswa UHPLC? Kijan pou w chwazi bon teknik chromatografi likid pou laboratwa w la

31 oktòb 2025

TAGS: HPLC vs UHPLC chromatografi likid chimi analitik flux travay kwomatografi Aijiren consommables kolòn HPLC Kolòn UHPLC analiz laboratwa konparezon kwomatografi UHPLC flakon

ki sa ki HPLC?

High-Performance Liquid Chromatography itilize kolòn ki chaje ak pi gwo patikil (tipikman 3-5 µm), opere nan presyon modere (souvan jiska ~ 400-600 bar), epi li lajman itilize pou analiz woutin nan pharmaceutique, tès manje ak laboratwa anviwònman an. Li serye, byen valide, ak konpatib ak anpil workflows ki egziste deja.

ki sa ki UHPLC?

Kwomatografi likid ultra-wo pèfòmans ogmante patikil ki pi piti anpil (souvan ≤2 µm) epi li opere nan presyon ki ogmante anpil (jiska ~ 1000-1500 bar oswa plis). Benefis yo gen ladan tan kouri pi vit, pi wo efikasite ak rezolisyon amelyore. Pou laboratwa ki manyen melanj konplèks, analiz tras oswa ki bezwen pi gwo debi, UHPLC se yon opsyon solid.

Lè pou itilize HPLC

HPLC se ideyal lè matris echantiyon ou a jere, demann debi yo modere, kontrent bidjè egziste, epi ou priyorite metòd valide ki estab. Si aplikasyon w lan enplike estanda ti tès molekil, QA\/QC workflows oswa pwotokòl byen etabli, HPLC rete yon chwa solid.

Lè pou itilize UHPLC

Si ou okipe echantiyon trè konplèks (egzanp, bio-echantiyon, metabolomik), bezwen woulman rapid, gwo sansiblite oswa separasyon pi file, Lè sa a, UHPLC ka pi bon envestisman an. Ou dwe konnen, sepandan, ke UHPLC mande pou kondisyon sistèm pi sevè (ba volim mouri, segondè-pèfòmans ponp, optimize consommables) ak yon pi gwo depans inisyal.

Matyè Consommables

Deplasman soti nan HPLC pou ale nan UHPLC tou gen enpak sou chwa consommables yo. Chwazi flakon bon jan kalite, sereng autosampler, filtè, ak kolòn plis enpòtan nan workflows UHPLC akòz tolerans ki pi sere. Pou egzanp, yon laboratwa ki sèvi ak UHPLC ta dwe konsidere flakon ki ba-adsorption, filtè ultra-pwòp ak pyès ki nan konpitè piki optimize pou kenbe pèfòmans.

Poukisa chwazi konsomasyon chromatografi Aijiren yo

Nan Zhejiang Aijiren Technology Co., Ltd., nou sipòte tou de workflows HPLC ak UHPLC ak consommables ekspè nou yo ki fèt. Ofri nou an gen ladan flakon sètifye, septa estokaj, filtè pwòp ak OEM\/ODM solisyon koutim. Lè l sèvi avèk consommables Aijiren, laboratwa yo jwenn pèfòmans serye, diminye kontaminasyon background ak pi bon repwodiksyon metòd.

Tou de HPLC ak UHPLC gen plas yo nan laboratwa modèn. HPLC rete pri-efikas ak solid pou anpil analiz estanda, pandan y ap UHPLC bay vitès ak rezolisyon amelyore pou senaryo gwo demann. Kle a se aliman enstriman ou, workflow, consommables, ak bidjè pou objektif analyse ou.

Kesyon yo poze souvan (FAQ)

Èske UHPLC toujou pi bon pase HPLC?

UHPLC ofri rezolisyon ki pi wo ak analiz pi rapid, men li vini ak pi gwo pri ak kondisyon ki pi sevè-konsa "pi bon" depann sou aplikasyon espesifik ou.

Èske mwen ka itilize menm kolòn pou HPLC ak UHPLC?

Tipikman pa. Kolòn UHPLC yo optimize pou presyon ki pi wo ak patikil ki pi piti yo, epi kolòn HPLC estanda yo ka pa fonksyone byen oswa san danje nan sistèm UHPLC.

Ki consommables kle mwen ta dwe ajou pou UHPLC?

Konsantre sou flakon ki ba-adsorption, filtè ultra-pwòp ak sistèm piki ki gen yon volim mò minim, pou kenbe fòm pik ak repwodiksyon nan UHPLC.
