Pesticide Residue Fast Test
Pesticide residue is a common problem. Pesticide residues maybe exist in grains, fruits and vegetables, agricultural products, and aquatic products.
Pesticide residues are harmful to human healthand. Many diseases can be caused by Pesticide residues.
As economic development improves quality of life, poeple pay more attention Pesticide residues.
3 ways to detect pesticide residue
| Chemical Test | Biochemical Test | Raman Spectrometer | |
| Inspection Equipment | Chromatograph, Mass spectrometer | Spectrophotometer | Raman spectrometer/ analyzer |
| Inspection Characteristic | Qualitative/ quantitative analysis | Rapid test kits | Qualitative & Semi-quantitative analysis |
| Cost | Expensive, approximately US$200 | Cheap, approximately US$10 | Reasonable, approximately US$70 |
| Operating Environment | Valuable laboratory | Can be measured in the field | Can be measured in the field |
| Professional Training | Requires professional for use | Easy process, easy to learn | Easy process, easy to learn |
| Test Time | 4~7 days | 30 mins | 30 mins |
| Report | Detectable pesticide name and concentration | Acetylcholinesterase inhibitory activity | Detectable pesticide name and relative concentration |
| Detection Type | All pesticides | Only show total content of organic phosphorus and carbamate. Unable to know the name and content of each pesticide. | All pesticides |
| Shortcomings | Personnel need professional training | Only know the total content of pesticides. Can’t detect pesticides such as organic ammonia, organic arsenic, nicotine. | Personnel need simple training |
| Legal Validity | As legally binding | Non-legally binding | Non-legally binding |
Raman spectroscopy is currently the most promising test solution for pesticide detection.
Raman spectroscopy is a fast, low-cost, and highly accurate solution for pesticide residues.
Test Module
Raman spectrometer: TR100 or TR500S
SERS chip: TS-AU3
Extraction module: FaPEx® (TACTRI pattern)
Raman spectrometer: TR100 or TR500S
SERS chip: TS-AU3
Extraction module: FaPEx® (TACTRI pattern)
Process
1. TACTRI has a pattern to extract pesticide from samples within 15 ~ 20 mins (FaPEx®).
2. Then use reflective type Raman analyzer with SERS, total measuring time 1 ~ 2 mins.
3. TR100 built-in spectrum comparing function, comparison result will be shown after measurement.
We provide pesticide residue fast test, whole process is very easy, save time and cost down, compared to traditional method which customers need to send samples to inspection agency, spend 3 ~ 5 days and lots of money.
Advantages
1. Fast pretreatment, fast measuring time.
2. Pesticide residue testing limit ~0.1 ppm.
3. TACTRI (Taiwan Agricultural Chemicals and Toxic Substances Research Institute) pattern for pretreatment FaPEx®.
4. Built-in comparing function, automatically show up result.
5. Self-built database easily, save the cost of authorization.
6. Handheld equipment is easy to carry, flexible application.
7. Easy process, easy to learn.
