Do I have to buy the reference material from the inspection office?
Do you have to buy the reference substance from the central inspection office? Recently, I want to do a small project and found that several reference substances are out of stock in the central inspection office. What should I do when the reference substance is out of stock in the central inspection office?
The National Standards Network summarizes the channels for purchasing reference/standard products at work:
Purchase directly from the Central Inspection Institute
Buy directly from the China Inspection Institute, including some provincial drug inspection institutes, such as Shanghai Drug Inspection Institute, Guangzhou Drug Inspection Institute, etc. Of course, you can also buy www.gbw.org.cn directly on the National Standard Products Network, and enter the product information you need in the search box to view the price. The number starting with YJ- (abbreviation for drug inspection) is the product of the China Inspection Institute
From UPS/EP/BP reference substance
Products that are out of stock in the central inspection can be directly purchased fromUPS/EP and other imported pharmacopoeia standard products ordered on the official website; this foreign pharmacopoeia product certification can also be recognized. The delivery time of such products is generally 3-5 or 4-6 weeks, and some common products are in stock on the national standard product network; the delivery time is about 1 week (the buyer receives the goods). For details, please consult the national standard product network for sales.
III. Purchase self-made reference substances
Some traditional Chinese medicine reference substances are not produced and sold by the Central Inspection Institute. At this time, you can choose to buy the reference substances made by the National Standard Product Network, and it is also acceptable to purchase products for self-calibration.
Finally, if the standard products of the Central Inspection Institute are out of stock and you have to use their products, you can contact some manufacturers that sell standard products and reference products to see if they are in stock. For example, the national standard product network consultation, at this time you can provide your batch requirements. Generally speaking, the national standard product network quotes the latest batch (expensive) for out-of-stock products, and the previous batch price will be cheaper. It depends on the product and requirements. Recommended reading:What information should be prepared for the purchase of toxic hemp standards and reference substances?
