Product Description
 
The Paraquat Rapid Test Kit is designed for fast on-site screening of paraquat residues in high-risk agricultural commodities such as tea, coffee, banana, sugarcane, maize/corn, soybean, rice, tropical fruits and selected raw materials.
 
For exporters, processors and QC laboratories, the biggest risk is often not testing itself, but discovering paraquat residue risk too late — after raw materials have been purchased, processed, packed, shipped or inspected by buyers.
 
This rapid screening solution helps QC teams identify suspicious batches earlier, allowing high-risk materials to be separated, further confirmed, or prevented from entering production and export channels.
 
It is a practical pre-laboratory risk control tool for tea exporters, coffee processors, tropical fruit suppliers, grain processors, agricultural trading companies and food safety laboratories.

Why Paraquat Rapid Screening Matters
 
Paraquat is a highly sensitive residue-control target in international food and agricultural trade.
 
For professional buyers, the key question is not only:
 
“Can paraquat be detected?”
 
but:
 
“Can we identify the risk before the loss becomes expensive?”
 
Rapid screening helps users:
 
* Detect suspicious batches earlier
* Reduce delayed discovery after processing or shipment
* Lower unnecessary laboratory workload
* Improve raw material acceptance control
* Support export risk management
* Make faster QC decisions in real supply chains
 
This makes the kit especially useful for front-end screening before laboratory confirmation.

Key Application Scenarios
 
1. Raw Material Intake Screening
 
For tea, coffee, maize, soybean, rice, sugarcane-related materials and feed raw materials.
 
Helps processors and traders screen incoming materials before storage or production.
 
⸻
 
2. Export Pre-Shipment Screening
 
For tea, coffee, banana, tropical fruits, grain and agricultural commodities.
 
Helps exporters identify high-risk batches before container loading, customs inspection, buyer testing or shipment.
 
⸻
 
3. Plantation Crop & Processing QC
 
For coffee, banana, sugarcane, oil-palm-related materials and tropical crop supply chains.
 
Helps users screen residue risk before batch mixing, processing or commercial delivery.
 
⸻
 
4. Pre-Laboratory Risk Screening
 
For QC laboratories and companies handling many samples.
 
Helps users screen suspicious batches first and prioritize samples that require confirmatory laboratory testing.

Optional Reader-Assisted Analysis
 
Results can be interpreted visually or with an optional dedicated reader.
 
When used with the reader, the system can:
 
* Improve positive / negative interpretation
* Provide semi-quantitative reference values
* Support digital documentation and traceability
* Help manage batch-level QC records
 
This upgrade is suitable for exporters, laboratories, processors and large agricultural QC programs requiring more standardized data control.

Laboratory-Backed Screening Capability
 
We are not only a rapid test strip supplier.
 
Our strength lies in an integrated system covering:
 
* In-house R&D
* Large-scale manufacturing
* Colloidal gold rapid screening technology
* Independent laboratory verification
 
With our own laboratories equipped with LC-MS/MS and GC-MS/MS systems, we can evaluate how rapid screening results align with laboratory reference methods in validated applications.
 
This helps support product optimization, matrix validation and long-term reliability in real agricultural supply chains.
 
For buyers, this means the product is not just a low-cost strip, but a more reliable front-end screening solution supported by laboratory verification capability.
