Profenofos Rapid Test Kit
Brand: FSTest
5–8 mins Rapid Readout Time | 0.5–10 mg/kg Tunable Matrix LOD | 10 Tests Complete Kit Pack | 12 Months Shelf Life (4–30°C) |
The FSTest Profenofos Rapid Test Kit is a professional-grade rapid screening tool engineered for the qualitative detection of profenofos residues in fresh fruits and vegetables.
Profenofos is a widely applied organophosphorus insecticide and acaricide. By eliminating the immediate necessity for complex and costly laboratory equipment (such as HPLC or GC-MS), this field-ready assay compresses agricultural chemical extraction into a simplified, room-temperature workflow, delivering highly reliable visual results in just 5 to 8 minutes for agricultural growers, fresh produce logistics, and food safety inspection agencies.
High-Speed Field Turnaround: Complete the entire workflow and read stable visual results within 5 to 8 minutes post-sample-preparation.
Versatile Matrix Detection Limits: Dynamically targets regulatory cut-off thresholds ranging from 0.5 mg/kg up to 10 mg/kg by adjusting simple sample supernatant dilution ratios.
Targeted Application Matrix: Validated across Head cabbage, Radish, Cauliflower, Chinese kale, Chili pepper, Bok choy, Radish leaves, Tomato, and Mangosteen.
High Specificity & Zero Cross-Reactivity: Proven unaffected by non-target agrochemicals up to 10 mg/L (including Chlorpyrifos, Acetamiprid, Triazophos, and Chlorothalonil).
Safe & Non-Toxic Formulation: Supplied with a specialized extraction solution certified as safe and non-toxic for operators during on-site field testing.

Validated across diverse fresh produce categories:
STEP 1 Extraction Cut produce into 0.5 cm pieces. Weigh 2 g into sampling bottle, add 3 mL extracting solution, shake 1 min, let stand 1 min. (Centrifuge if cloudy). | STEP 2 Matrix Dilution Pipette X µL supernatant into a 2 mL tube, add Y µL extracting solution according to the matrix guide, and vortex for 10 seconds to mix thoroughly. | STEP 3 Load Cassette Ensure 20–40°C environment. Mount exactly 100 µL of prepared final sample solution directly into the sample hole of the cassette. Start timing. | STEP 4 Read at 5–8 Mins Interpret visual lines strictly at 5–8 minutes. Visual readouts become strictly invalid after 8 minutes due to late chemical shifts. |
Negative (-): Both Control (C) line and Test (T) line develop strong, distinct red bands. Profenofos residue is safely below the targeted matrix LOD limit.
Positive (+): Control (C) line develops normally, but Test (T) line is visibly lighter or fails to appear → Profenofos residue ≥ targeted matrix LOD limit.
Invalid: Control (C) line fails to show any visible color band. Re-testing with a new cassette is required.
Adhere to strict operational parameters to ensure maximum screening accuracy:
Qualitative Screening Purpose: Engineered strictly for qualitative preliminary screening; not intended for precise quantitative concentration evaluation.
Matrix Dilution Accuracy: Strictly execute the X & Y dilution ratio corresponding to the commodity type to calibrate reading against exact regulatory MRL cutoffs.
Strict Time Window: Read visual test results strictly between 5–8 minutes after loading the cassette; results observed after 8 minutes are invalid.
Kit Components Included: 10 Test cassettes, 2 mL Centrifuge tubes (x10), Extracting Solution (50 mL) x1, 30 mL Sampling bottles (x2), User Manual.
Required Equipment (Not Provided): Scissors, electronic balance, micropipettes (X & Y µL, 100 µL), vortexer, centrifuge (optional, for cloudy extracts), and timer.
