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
0.5 ppb.
Storing and Handling Reagents
• 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
not in use.
• If Stop Solution comes in contact with eyes, wash thoroughly for 15 minutes
with cold water and seek immediate medical help.
Sensitivity
The Atrazine immunoassay cannot differentiate between the various triazines
and metabolites, but it detects their presence in differing degrees.
The following compounds are not detectable at 10,000 ppb.
