Interpretation

Sample #1 — Sample reading is less than the readings for both calibrators.

Therefore the sample concentration of Atrazine is greater than both 0.5 ppb and

3.0 ppb Atrazine.

Sample #2 — Sample reading is between the readings for the 0.5 ppb and

3.0 ppb Atrazine calibrators. Therefore the sample concentration of Atrazine is

between 0.5 ppb and 3.0 ppb.

Sample #3 — Sample reading is greater than the readings for both calibrators.

Therefore the sample concentration of Atrazine is less than both 3.0 ppb and

• Wear protective gloves and eyewear.

• When storing reagent sets for extended periods of time, keep them out of

direct sunlight. Store reagents at a temperature of 4 °C when not in use.

• Keep the foil pouch containing the Atrazine Antibody Cuvettes sealed when

• If Stop Solution comes in contact with eyes, wash thoroughly for 15 minutes

with cold water and seek immediate medical help.

The Atrazine immunoassay cannot differentiate between the various triazines

and metabolites, but it detects their presence in differing degrees.
