Analysis of Concentrations of Clopyralid in Compost Piles
14 Apr 2013Clopyralid is a commonly used herbicide used to kill unwanted annual and perennial broadleaf plants in turf and lawn, range, pasture, right-of-ways, and some agricultural crops. When administered at effective doses, Clopyralid binds to the plant growth receptors causing uncontrolled and disorganized growth that ultimately leads to the plants death in a few days or weeks depending upon the species. This application note presents a method, using an extraction assay and HPLC, to analyze the Clopyrapid concentration in soil samples. The compost from the Pittsford leaf pile was determined to contain a concentration of 17.4 ± 2.80 µM Clopyralid. This concentration in the soil is high and would cause damage to plants such as the Red clover.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns.
