Quality Control
We undergo quality check for all synthesized products.
And, we also check yield by measurement of absorbance.
purification methodquality standard
GEL filtrationmore than 85%
OPC purificationmore than 90%
HPLC purificationmore than 95%
We undergo resynthesis immediately for the products not passing our quality standard due to the result of quality check and short yield.
In this case, delivery will be delayed beyond expected delivery time.
