1 Guide to Chemical pesticides have become an integral part of the agricultural toolbox, offering protection to crops from destructive pests. However, some unfortunate side effects of their use include potential leaching of these, oftentimes, harmful chemicals into the environment and their eventual presence in the human food chain. As a result, pesticide residue analysis has become a critical testing process for many different types of laboratories. Unfortunately, pesticide residue testing is a long, expensive and complicated process, covering hundreds of different compounds, made even more daunting by the plethora of varying pesticide types that sometimes require different testing techniques for identification. Fortunately, as the leader in HPLC, GC, LC/MS and GC/MS pesticide CRMs, SPEX CertiPrep is happy to assist all of our customers with all of their pesticide CRM needs. For your convenience we have designed a pesticide residue testing kit which includes 144 of the most commonly analyzed pesticides per EPA, AOAC, FDA and other international testing methods. The kit is structured to maximize stability and solubility while minimizing unwanted analyte interaction and interference; enjoy shorter calibration times, fewer injections and money savings, as compared to purchasing individual pesticide standards. As a companion piece to this new product, we have assembled this solubility guide, which covers all 144 pesticides included in the kit (SPEX CertiPrep part number SPXPR-KIT). We hope that you will find this information helpful and use it in order to assist you with your sample preparation and analysis. CAN T FIND THE STANDARDS YOU ARE LOOKING FOR? SPEX CertiPrep can make custom standards to meet your exact needs. Call your local sales representative for more information. SOLUBILITY is defined as a chemical property referring to the ability of a given substance, the solute, to dissolve into a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called a saturated solution. The following pages show the solubility of pesticide kit compounds in some of the most popular solvents. Use the legend below as a guide for concentrations of those solvents. NOTE: All values are a compilation of resources and reference lists that are available upon request. The chart below shows the concentration ranges for the tables on the following pages.
