如何查找COA批号
批号可以在产品标签上"批“ (Lot或Batch)字后面找到。
如果您查询到的批号为 TO09019TO 等,请输入去除前两位字母的批号:09019TO。
如果您查询到的批号含有填充代码(例如05427ES-021),请输入去除填充代码-021的批号:05427ES。
如果您查询到的批号含有填充代码(例如 STBB0728K9),请输入去除填充代码K9的批号:STBB0728。
部分情况下,可能未在线提供COA。如果搜索不到COA,可在线索取。
If you know approximately how much glucose is present, dilute the sample down to 0.5 to 50 ug of glucose and use between 10 to 200 ul sample volume. If you do not know how much glucose is present, you should assay the undiluted sample and dilutions of it. Based on the dilution factor you can determine the glucose concentration.
Although we have not done it, you should be able to scale down the procedure as long as you have pipettes capable of dispensing accurate ul volume quantities and an instrument that can monitor the 340 nm wavelength.
You can deproteinize by using barium hydroxide, B4059, and zinc sulfate, Z2876, by adding 0.2 ml of sample to 1.8 ml of water, swirl and mix, then 1.0 ml of barium hydroxide, swirl and mix, then 1.0 ml of zinc sulfate, swirl and mix thoroughly by shaking, and then filter or centrifuge to obtain clear filtrate.
You can decolorize a solution by adding a small amount of charcoal to the solution, swirl, then filter or centrifuge to remove charcoal.
You can degas a solution by either putting it under a vacuum or by bubbling nitrogen through it.
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
