PCP Immunoassay Test Kit
The HNU-Hanby pentachlorophenol (PCP) test kit rapidly analyzes for PCP in soil samples. The test kit can only detect those PCP carriers that contain aromatic compounds. The test kit estimates PCP concentrations in soil samples indirectly by measuring petroleum hydrocarbon carrier solvent for the PCP. The carrier solvent concentration ratio must be constant for the test kit results to be useable. The test kit uses the Friedel-Crafts alkylation reaction to detect aromatics and petroleum in soil samples at a detection level of 1.0 per million for aromatic compounds. The test kit was used to screen and quantify PCP contamination in soils in Morrisville, NC with samples collected from Winona, MO. The method produced Level 1 quality assurance data during the demonstration. When PCP was present it was always detected by the test kit. HNU systems recently introduced a similar method that could measure PCP more directly by detecting chlorinated compounds in soil and water using the same principle.
