A high purity HPLC solvent. For improved reproducibility and detection sensitivity of the chromatography, the stability of the analyte, stability of the mobile phase, clogging in the line and filter, sensitivity and stability of the detector have been considered, and the product has guaranteed quality with respect to change in refractive index due to water, peroxides, nonvolatile matters, or impurities in the solvent, UV absorption, and fluorescent substances and more. It is filtered through a 0.45 µm filter in the final step to ensure highly reproducible data and a long column life.

Pesticides, PCBs and Herbicides

The EPA is tasked with the monitoring of environmental systems as they pertain to contamination and human health. The methods issued by the EPA are created to respond to specific toxins or persistent organic pollutants (POPs) found in environmental samples such as soil, source water, drinking water, and waste. In particular, pollutants such as polychlorinated biphenyls (PCBs), which were in widespread industrial use up until their restriction, are of concern due to their stable and persistent nature in the environment. Another group of chemicals of high concern is the hundreds of commercial pesticides and herbicides in use in the world today. Pesticides, from algaecides to virucides, are used in large quantities in industrial and private agriculture. The concern over human pesticide exposure over the past few decades has led to extensive monitoring of these pesticides. It has been reported that over 98% of insecticides and 95% of herbicides affect areas other than their intended target product. It is essential that monitoring agencies have accurate standard mixes to measure the pesticide levels in the environment.

Many new pesticides are now being tested using highly sensitive LC/MS techniques, in addition to traditional GC techniques, to determine minute amounts of residue in environmental samples and food products.

At SPEX CertiPrep, we facilitate ease of monitoring and testing of pesticides by creating pesticide test mixes to suit your monitoring needs. SPEX CertiPrep is the leader in offering pesticide standards designed to work within EPA, AOAC and FDA analytical testing methods using all of the leading analytical techniques: LC, LC/MS, GC, and GC/MS. Many pesticide standard mixes are readily available in our catalog along with a large list of single pesticide standards. In addition, custom pesticide mixes can be made to your specifications to create a mix that meets your needs.

Description: Phosphatidylcholines (PCs) are amphipathic molecules. PC accounts for approximately 40–50% of the total cellular phospholipids. They are usually located on the outer leaflets of the biological membrane bilayer. The list of Phosphatidylcholine products offered by Avanti is designed to provide compounds having a variety of physical properties. Products available include short chain (C3-C8 are water soluble and hygroscopic), saturated, multi-unsaturated and mixed acid PC′s. All of the products are purified by HPLC, and special precautions are taken to protect the products for oxidization and hydrolysis. Application: 15:0 PC (1,2-dipentadecanoyl-sn-glycero-3-phosphocholine) may be used to prepare giant unilamellar lipid vesicles (GUVs). It has been used as an internal standard for lipidomics analysis in BXD liver samples and plasma samples.
