The storage conditions for reference substances and standards are
The package of the reference product received says that the storage condition is 4 ° C, but you shipped it to me directly in an ordinary box without any protection. Has this product deteriorated? Should I return it?
Answer:reference substanceThe storage temperature on the packaging of the standard product is the temperature condition for long-term storage, not the transportation condition. Under normal circumstances, during the short-term stability inspection of the reference product, the stability monitoring of the compound under extreme conditions (-20 ° C and 50 ° C) will be carried out for 12 consecutive days to prove that it is stable under this condition. If the above conditions are not met, we will use dry ice transportation to ensure the accuracy of the quantity of the reference product!
