Hauv thaj tsam ntawm kev ua haujlwm siab ua kua chromatography (HPLC) thiab lwm yam kev tshuaj ntsuam xyuas, kev xaiv ntawm tubing tuaj yeem cuam tshuam qhov raug thiab kev ntseeg siab ntawm cov txiaj ntsig. Polyether ether ketone (PEEK) tubing tau tshwm sim raws li cov khoom nyiam, muab kev sib xyaw ntawm txhua yam muaj zog thiab tshuaj tiv thaiv. Kab lus no delves rau hauv qhov zoo ntawmPEEK tubing, tshwj xeeb tshaj yog 1/16 "sab nraud txoj kab uas hla (OD) sib txawv, thiab muab kev taw qhia ntawm kev xaiv qhov tsim nyog sab hauv txoj kab uas hla (ID) rau ntau yam kev siv.
Qhov tseem ceeb ntawm kev xaiv tubing hauv kev siv tshuaj ntsuam xyuas
Xaiv txoj cai tubing yog qhov tseem ceeb hauv kev teeb tsa kev txheeb xyuas. Nws ua kom:
•Tshuaj Compatibility: Tiv thaiv kev tshwm sim ntawm cov khoom siv tubing thiab cov kuab tshuaj los yog cov qauv.
•Siab Resistance: Nrog rau kev ua haujlwm siab ntawm qhov system tsis muaj deformation.
•Dimensional raug: Ua kom tus nqi ntws zoo ib yam thiab txo cov ntim tuag.
Qhov zoo ntawm PEEK Tubing
PEEK tubing sawv tawm vim nws:
•Siab Mechanical Strength: Muaj peev xwm tiv taus siab txog li 400 bar, ua rau nws tsim nyog rau kev siv siab.
•Tshuaj tiv thaiv: Inert rau feem ntau cov kuab tshuaj, txo qhov kev pheej hmoo ntawm kev kis kab mob thiab ua kom ntseeg tau qhov tseeb ntawm kev soj ntsuam cov txiaj ntsig.
•Thermal stability: Nrog lub melting point ntawm 350 ° C, PEEK tubing tseem ruaj khov nyob rau hauv siab kub.
•Biocompatibility: Tsim nyog rau cov ntawv thov uas muaj cov qauv tshuaj lom neeg, kom tsis txhob muaj kev cuam tshuam tsis zoo.
Nkag siab 1/16 "OD PEEK Tubing
1/16 "OD yog tus qauv loj hauv HPLC systems, sib xws nrog cov fittings feem ntau thiab cov khoom sib txuas. Qhov kev tsim qauv no yooj yim rau kev sib koom ua ke thiab kev saib xyuas.
Xaiv qhov tsim nyog Inner Diameter
PEEK tubing muaj nyob rau hauv ntau yam IDs, txhua catering rau cov kev xav tau tshwj xeeb:
•0.13mm ID (Liab): Qhov zoo tshaj plaws rau cov ntawv thov qis qis uas qhov kev tswj hwm yog qhov tseem ceeb.
•0.18mm ID (Natural): Haum rau nruab nrab ntws tus nqi, ntsuas qhov siab thiab ntws.
•0.25mm ID (Blue): Feem ntau siv hauv cov ntawv thov HPLC txheem.
•0.50mm ID (daj): Txhawb nqa tus nqi siab dua, haum rau kev npaj chromatography.
•0.75mm ID (ntsuab): Siv nyob rau hauv daim ntawv thov uas yuav tsum tau muaj ntau txaus txaus yam tsis muaj siab buildup.
•1.0 hli ID (Grey): Zoo tagnrho rau cov ntawv thov ntws siab heev, txo qis qis qis.
Thaum xaiv tus ID, xav txog qhov viscosity ntawm koj cov kuab tshuaj, qhov xav tau txaus tus nqi, thiab kev txwv qhov system siab.
Cov kev coj ua zoo tshaj plaws rau kev siv PEEK Tubing
Txhawm rau kom muaj txiaj ntsig zoo ntawm PEEK tubing:
•Zam tej yam hnyav: PEEK tsis sib haum nrog cov concentrated sulfuric thiab nitric acids. Tsis tas li ntawd, cov kuab tshuaj xws li DMSO, dichloromethane, thiab THF tuaj yeem ua rau lub raj txuas ntxiv. Ceev faj thaum siv cov kuab tshuaj no.
•Cov txheej txheem txiav kom raug: Siv cov tubing cutters tsim nyog los xyuas kom huv si, txiav txiav, tuav lub foob kom raug thiab txaus sib xws.
•Kev tshuaj xyuas tsis tu ncua: Txheeb xyuas cov cim ntawm kev hnav, xws li cov kab nrib pleb lossis cov xim tsis zoo, txhawm rau tiv thaiv kev ua haujlwm tsis zoo.
