Kontwòl Kalite pwodwi
1.Konpayi nou an te jwenn kalifikasyon laboratwa CNAS
2.Our konpayi gen nikleyè mayetik sonorite (Bruker 40OMHZ) spectrometer, mas spectrometer (dlo SQD), analyse HPLC (ekipe ak detektè UV, detektè PDA, detektè ESLD) ak lòt enstriman analyse asire bon jan kalite pwodwi.
3.Our konpayi kenbe kontak sere ak enstiti rechèch syantifik tankou Shanghai Enstiti pou kontwòl dwòg, Nanjing platfòm sèvis piblik pou byomedsin ak Shanghai Enstiti nan endistri pharmaceutique.Sant nasyonal enspeksyon bon jan kalite pwodwi chimik a se mwens pase 100m lwen konpayi nou an epi li ka bay yon seri konplè sèvis tès twazyèm pati pou asire bon jan kalite pwodwi konpayi an.
Solisyon
1. Si achtè a gen nenpòt objeksyon anvan li resevwa pwodwi a ak akseptasyon, li ka mete devan li anvan li pase akseptasyon an.
2. Lè achtè a bay pwoblèm kalite nòmal nan nenpòt fason (ki gen ladan telefòn, faks, imèl, elatriye), nou pral reponn nan lespas 4 èdtan, bay solisyon preliminè nan lespas 12 èdtan, epi bay solisyon konplè ak mezi prevansyon ki koresponn nan 24 èdtan.
3. Si akseptasyon an montre ke bon jan kalite a, kantite, spesifikasyon oswa pèfòmans nan pwodwi yo pa satisfè kondisyon yo espesifye pa achtè a, nou vle retounen, echanj oswa ranplir san kondisyon nan 8 jou soti nan dat la nan resevwa avi alekri soti nan. achtè a.
4. Konpayi nou an kenbe dosye pwodiksyon ak dosye tès tout pwodwi pou 5 ane pou kliyan yo revize nenpòt ki lè.
