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.

The Process of FaPEx and QuEChERS
| FaPEx Procedure | QuEChERS Procedure | |
| Sample preparation and extraction |
|
1.Add 10ml volume of 1% Acetic Acid(HOAc) in Acetonitrile(MeCN) solution. 2. Add homogenizer. 3. Add extraction powder. 4. Vortex vigorously. |
| Sample extract cleanup |
Clean and Extract with FaPEx kit | 5. Centrifugation. 6 .Collect supernatants. 7. Add clean-up powder. 8. Vortex, centrifuge. 9. Add up to volume. |
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
LC-MS/MS Analysis
Dry 1 mL with Nitrogen
Add an Acetone : Hexane (1:1,v/v) solution into test solution to 1mL
GC-MS/MS Analysis
