The FSTest Triazophos Rapid Test Kit is a professional-grade, rapid screening tool engineered for the qualitative detection of triazophos residues in fresh fruits and vegetables.

Triazophos is a widely monitored organophosphorus insecticide and acaricide. By eliminating the immediate necessity for complex and costly laboratory infrastructure (such as HPLC or GC-MS), this field-ready assay compresses agricultural chemical extraction into a simplified room-temperature workflow, serving as a vital first-line defense in fresh produce logistics, crop supply chain collection points, and corporate quality compliance screening programs in just 5 to 8 minutes.

2. Key Benefits

High-Speed Field Turnaround: Complete the entire screening assay workflow and achieve highly reliable visual result readouts within just 5 to 8 minutes post-sample-preparation.
Ultra-High Sensitivity: Specifically calibrated to yield dependable qualitative screening at a strict, ultra-low Limit of Detection (LOD) of 0.05 mg/kg (ppm) across various fruit and vegetable matrices.
Complete Package Architecture: Arrives fully packed with 10 test cassettes, 1 large bottle of dedicated extracting solution (100 mL), 2 sampling bottles (30 mL), and a user manual.
Definite Visual Interpretation: Utilizes a competitive lateral flow format where an increasing insecticide concentration causes the Test (T) line to fade or completely disappear, removing analytical ambiguity.
Safe, Long-Term Ambient Storage: Unopened test kits can be safely kept tightly sealed in a cool, dry location between 4–30°C for a full guaranteed shelf-life of up to 12 months.

4. Applicable Sample Types

Calibrated for multi-matrix agricultural screening across comprehensive produce categories:

Fresh Fruit Commodities (Apples, pears, citrus, stone fruits, berries, grapes, tropical fruits) Leafy & Brassica Vegetables (Cabbage, spinach, kale, lettuce, celery, broccoli) Solanaceous, Cucurbits & Roots (Tomatoes, peppers, cucumbers, carrots, potatoes, radish)

5. Test Procedure

STEP 1

Extraction

Cut fresh sample into 0.5 cm pieces. Weigh 2 g into sampling bottle, add 10 mL Extracting Solution, shake 1 min, let stand 1 min.

STEP 2

Clarification

Check supernatant clarity. If liquid layer is cloudy or turbid, transfer 1 mL into a tube and centrifuge at 4000 rpm for 3 minutes.

STEP 3

Load Cassette

Ensure 20–40°C environment. Mount exactly 100 µL of prepared clear test solution directly into round sample hole on 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.

Visual Results Determination Guide:

Negative (-): Both Control (C) line and Test (T) line develop color normally. Triazophos residue is safely below 0.05 mg/kg.
Positive (+): Control (C) line develops normally, but Test (T) line is visibly lighter or fails to appear → Triazophos residue ≥ 0.05 mg/kg threshold limit.
Invalid: Control (C) line fails to show any visible color band. Re-testing with a new cassette is required.

6. Performance & Crucial Operational Controls

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.
Time-Sensitive Exposure: Perform test within 1 hour after removing cassette from protective packaging to avoid moisture interference.
Strict Time Window: Read visual test results strictly between 5–8 minutes after loading cassette; results observed after 8 minutes are invalid.

7. Included Components & Auxiliary Equipment

Kit Components Included: 10 Test cassettes, Extracting Solution (100 mL) x1, 30 mL Sampling bottles (x2), User Manual.
Required Equipment (Not Provided): Scissors, electronic balance (2 g precision), micropipette (100 µL), centrifuge (optional, for turbid extracts), and timer.
