LOD (Limit of Detection): varies with wine or particular fruit; details provided in product insert

* 1.0 ppb chlorpyrifos in wine; 50 ppb carbaryl in wine
* 0.2 ppb chlorpyrifos in sultanas; 0.5 ppm carbaryl in sultanas


Assay Range:
This is a semi-quantitative screening assay, designed to compare samples against a negative control, a low concentration residue standard and a high concentration residue standard.

For wine samples:

* low standard = 1.0 ppb chlorpyrifos and 100 ppb carbaryl
* high standard = 5.0 ppb chlorpyrifos and 500 ppb carbaryl


For dried fruit samples:

* low standard = 5.0 ppb chlorpyrifos and 1.0 ppm carbaryl
* high standard = 25 ppb chlorpyrifos and 5.0 ppm carbaryl


Reagents Provided:

* Oxidizing Agent Concentrate
* Oxidizing Agent Diluent
* Microwell Solution
* Neutralizing Agent
* Enzyme
* Substrate
* Chromogen
* Stopping Solution
* Materials for Controls for Specific Matrix (Contact EnviroLogix)
