Descripción

Application

• Determination of Mycotoxins in Brown Rice Using QuEChERS Sample Preparation and UHPLC-MS-MS.: Sodium citrate tribasic dihydrate is used in the QuEChERS method to extract mycotoxins from rice. This research improves food safety by providing a reliable method for detecting harmful mycotoxins in food products (Jettanajit & Nhujak, 2016).

Other Notes

Buffer component in the preparation of total ribosomal RNA from E. coli.
