Real Bovine Chondroitin Sulfate Sodium with 90% CPC Titration Without Adulteration
We Jiaxing Hengjie Biopharmaceutical Co.,ltd. produces and supplies Real Bovine Chondroitin Sulfate Sodium with 90% assay by CPC titration without any adulteration.
When you buy chondroitin sulfate sodium, be careful about the Auldterated Chondroitin Sulfate (Fake Chondroitin Sulfate).
If you are receiving an offer below below two chareacters, chances are big that it is FAKE CHONDROITIN.
1. Chondroitin with unusual low price. We have received feedbacks from customers that they buy 90% purity chondroitin sulfate with price like USD10-USD20/KG, as a manufacturer of chondroitin, we are pretty sure that the product cost of 90% purity chondroitin is far more than USD20.0/KG. Compare this price with the market price of chondroitin, at least you will realise that something is not right.
2. Certificate of Analysis showing assay of 90% by all the testing methods you could thinking of including: CPC Titration, HPLC, Carbazole or even Enzymatic HPLC, such as below:
Manufacturer of chondroitin usually only show one or two testing method of assay for one specific batch. It is very unusual that a batch of chondroitin sulfate that could pass all the testing methods, because different testing methods will generate different results. Take Carbazole method for example, it will have much lower results than HPLC or CPC. Enzymatic HPLC will also have a much lower results than CPC or HPLC.
This is Called "Economically motivated adulteration "of chondroitin sulfate. Google "Adulteration of Chondroitin Suflate", then you will see more news about this issue. Up to know the known materials that are used to adulterate chondroitin sulfate include : sodium alginate, propylene glycol alginate sulfate sodium, and sodium hexametaphosphate.
As a manufacturer of chondroitin sulfate for 20 years, our company had been NSF-GMP Verified since the year of 2012, and DMF documentation for Chondroitin Sulfate is available. We never compromise on the quality of chondroitin, and we never cheat on the customers.

| The chromatogram of the enzymatically digested sample solution as obtained in the test for the limit of nonspecific disaccharides shows three main peaks corresponding to △DI-4S, △DI-6S,△DI-OS in the enzymatically digested standard solution. By peak area response, △ DI-4S is the most abundant, followed by the △ DI-6S, with △ DI-OS being the least abundant of the three | ||||||||

How to Identify the Fake Chondroitin Sulfate ?
1. Use Enzymatic HPLC testing. Enzymatic HPLC could only show the content of chondroitin sulfate, adulterant will be easily identified. If you are not able to perform this testing in your own lab, send a sample to an independant lab, A well known laboratory in the USA named as "Analytical Laboratories In Anaheim, Inc." is able to conduct this testing.
2. Or you can send a sample to our company, we will perform the Enzymatic HPLC testing, and advise you the result, for free.
