Product Overview
The Cadmium Rapid Test Kit is a practical and field-ready solution for detecting cadmium contamination in durian and a wide range of agricultural products.
It is specifically developed for export-oriented supply chains requiring:
• Fast screening
• Reliable results
• On-site decision-making
Typical tested commodities include:
Tropical Fruits (Southeast Asia focus):
• Durian
• Mango
• Pineapple
• Banana
• Papaya
High-risk export fruits:
• Citrus (orange, mandarin, lemon, grapefruit)
• Apple
• Berry fruits (strawberry, blueberry)
Other matrices:
• Vegetables
• Grains & beans
• Tobacco

Performance & Validation
• Cross-validated with AAS and ICP laboratory methods
• Demonstrates strong consistency with laboratory testing results
• Designed for routine screening in export environments
• Widely adopted in Southeast Asia over the past two years
⸻
Sensitivity & Detection Capability
• Standard LOD: 50–100 μg/kg (ppb)
• Customizable LOD: 0.02–0.03 mg/kg
This sensitivity level is already aligned with practical export screening needs and has been proven stable in real-world applications.

Proven Beyond the Laboratory — Trusted in Real Export Supply Chains
Our Cadmium Rapid Test Kit has been extensively validated through real-world use in high-volume export environments.
With over 20 years of dedicated rapid test manufacturing experience, our products have been deployed across Southeast Asia and used by leading durian exporters handling large-scale international shipments.
Our solutions have also supported major international events such as the Olympic Games and Asian Games, where testing accuracy, consistency, and reliability are non-negotiable.
This depth of long-term, high-frequency validation clearly distinguishes us from ordinary manufacturers.
We are not just supplying a test kit — we are providing a proven risk control tool trusted by real exporters under real market pressure.
KIT CONTENTS
-SmarKIT Cadmium Rapid Test (40/50 tests /kit)
-PBST Buffer (1 bottle/kit, 30ml)
-Buffer A (1 bottle/kit, 15ml)
-Packing Insert (1 set /kit)
TEST PROCEDURE
Read the entire procedure carefully before performing any test.
Keep the test kit and reagent at room temperature(20℃~30℃) before testing.
1. Prepare samples according to chapter 7 (Sample preparations).
2. Remove the Cadmium Rapid Test from sealed pouch.
3. Hold the dropper vertically and transfer 3 full drops(around 100µL) of solution to the specimen well (S) and then start the timer.
4. Wait for red bands to appear. The result should be read in approximately 3-5 minutes. Do not interpret results after 5 minutes.
Reading results
Negative:
The Test Line (T) is the same as or darker than the Control Line (C). It is negative.
POSITIVE:
The Test Line (T) is lighter than the Control Line (C), or there is no Test Line. It is positive.
INVALID: Reference Line fails to appear.
Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for an invalid result.
Review the procedure and repeat the test with a new test kit. Stop using the test kit immediately if the problem is not solved and contact your local distributor.
