The detection method of aflatoxin in peanutsFAPASInternational Capability Verification

Recently, our company (Giant Research Technology)GETECH）Received from the UKFAPAS(Food Analysis Performance Assessment Scheme)organizationPeanutsAspergillus flavusBAspergillus flavusGTotal Aspergillus flavusThe results of the testing capability verification show satisfaction. This indicates that our company's ability to detect aflatoxins in peanuts has reached the level of international industry laboratories.

Finally, our company's participation in the detection of aflatoxin residues in peanuts yielded satisfactory results (see39numberZ-Score）.

FaTEx gen fungal toxin specific column with 11 multifunctional columns

FaTEx gen fungal toxin specific column, based on multiple adsorption principles such as similarity compatibility and ion exchange. When the sample extraction solution passes through the SPE column in one step, impurities are retained on the packing. After passing through a 0.22 micron filter membrane, the target substance solution is obtained and loaded onto the machineLC-MSMSanalyze

FaTEx-gen SPEpillarThe purification method has been verified to be applicable toCorn, soybeans, rice, peanuts, peanut butterWait for the substrate and test for HAflatoxinB1, H aflatoxin B2, H aflatoxin G1, H aflatoxin G2, ochratoxin A, T-2 toxin, HT-2 toxin, vomitoxin, zearalenone, fumonisin B1, fumonisin B2together11Fungal toxins, other types of toxins are welcome to be verified.
