Walnut Free Test is a lateral flow test that determines walnut residues in food products and production environments from solid, liquid, and surface samples.

LATERAL FLOW CHARACTERISTICS:

• Sandwich quantitative lateral flow test in cassette format available in 10 or 30 tests
• Qualitative results can be interpreted visually without a lateral flow reader
• Pair with the optional 3PR Mini Reader or S-Flow Reader to obtain qualitative and quantitative interpretation of results with advanced features for traceability
• A third hook line prevents false negative results due to overload of target analyte
• Limit of detection (LOD) for food samples and CIP rinse: 3.0 ppm (3.0mg/kg) walnut (0.51ppm walnut protein)
• Limit of quantification (LOQ) for foos samples and CIP rinse: 5.0ppm (5.0mg/kg) walnut (0.85ppm walnut protein)
• Limit of detection (LOD) for surface samples: 0.4μg/100cm²
• Calibration range for quantification of food samples and CIP rinses: 5-128ppm
• Quick time to result: 5 mins
• Broad range of validated matrices
• Room or refrigerator storage at 4-30 deg C
