1. BACKGROUND

iCheck®- Plumbum strip is lateral flow immunochromatographic assay based on a competitive immunoassay format. With iCheck® strip reader, it measures 0-50ppb of cadmium in water.

2. MATERIALS PROVIDED

1) iCheck®-Pb strip (25/pk).

2) Microwells coated (25)

3) Dilution buffer (5mL)

4) Reagent A (1mL)

5) 200µL Pipette Tip (50)

6) Pb QR Code

7) Product Manual

3. Materials required but not provided:

1) 200 and 1000µL precision micropipette

2) iCheck® Strip reader (with ZERO card and Machine Calibration)

3) Thermostat

4) Timer

5) Distilled water or pure water

6) 10mL Extraction tube

4. INTERPRETATION OF THE RESULTS

1) Test range: 0-50ppb, LOQ 3.0ppb.

2) If there is no line in control zone, the test is invalid and the sample should be re-tested by using a valid test strip.

3) If reading is 50 ppb, the sample water should be further diluted in pure water such that the diluted sample reading results are in a range of 0-50ppb and reanalyzed to obtain accurate results. The dilution factor must be included when the final result is calculated.
