FAST PESTICIDE EXTRACTION
 
 
What is FaPEx?

FaPEx is the abbreviation of Fast Pesticide Extraction, which is the fast extraction technique of pesticide residue in agricultural products. FaPEx is now the fastest method in the world. This technique was researched and developed by Taiwan Agricultural Chemicals and Toxic Substances Research Institute (TACTRI), and was awarded a patent by the Taiwanese government in 2015.

FaPEx is easier and more efficient than the QuEChERS method. FaPEx provides the following benefits: triple the total efficiency, use less operating equipment, cut at least 60% of labor costs, use at least 50% less organic solvents, and have less waste.

FaPEx Benefits

1. Extract more than 300 pesticides simultaneously.

2. Easier and more efficient extraction.

3. Cut at least 60% of labor costs.

4. Less operating equipment.

5. Less organic solvent and waste.

FaPEx Operation Procedure
FaPEx-gen and FaPEx-chl
Weigh the homogenized sample to 2g+0.004g
FaPEx-cer and FaPEx-tea
Weigh the homogenized sample to 1g+0.002g
Add 2mL pure water, stand for 10 minutes
 
Add 10 mL volume of 1% Acetic Acid(HOAc) in Acetonitrile(MeCN) solution, then vortex for 30 seconds
Transfer 5 mL test solution into FaPEx kit, controlling the liquid flow reat a 1 drop per second
Collect all the test solution
 
Prepare 1 mL

Dry 1 mL with Nitrogen
Add an Acetone : Hexane (1:1,v/v) solution into test solution to 1mL
GC-MS/MS Analysis
FaPEx performance recognized by FAPAS 19195QC
FaPEx participated in the 2015 FAPAS 19195 ability test through the Drug Toxicology Laboratory of the Council of Agriculture in 2015,
and the performance evaluation results were acceptable.
