In general, a pesticide is a biological agent or chemical that deters, kills, incapacitates, or discourages pests. Pesticides can be classified by target organism (insecticides, fungicides, pediculicides, rodenticides and so on) and chemical structure (biological, organic, inorganic, synthetic etc.). And herbicides, also commonly known as weedkillers, are chemical substances used to control unwanted plants. Herbicides are classified in various ways, such as the activity, chemical family, timing of application, mechanism of action, and method of application.
Although pesticides and herbicides are benefits for agriculture and our life, these chemicals also have drawbacks, such as potential toxicity to other species and humans. Some chemicals used in pesticide and herbicide formulas have toxic properties or could form toxic by-products, potentially causing risks to human and animal health and environmental damage. Pesticides, herbicides, and their degradation products can migrate from their point of application through the air, plants, water, soil, animals, and microorganisms. Over 1,000 pesticides and herbicides are regulated by government agencies, and we need powerful and rapid analytical methods to detect a wide scope of pesticide and herbicide compounds, and their degradation products, in a wide range of different sample matrices.
Pesticide and Herbicide Analysis at Creative Proteomics
Based on years of experience on pesticide and herbicide analysis, Creative Proteomics can analyze various pesticide and herbicide categories to assist screening and quantitation at very low levels, including but not limited to:

- Herbicide: Dicamba, dichlorprop, dinoseb, alachlor, atrazine, benefin, bromacil, butachlor, butylate, cycloate, eptam, ethalfluralin, hexazinone, isopropalin, metolachlor, metribuzin, molinate, MCPA (2-methyl-4-chlorophenoxyacetic acid), norflurazon, oxadiazon, oxyfluorfen, pebulate, pendimehtalin, prodiamine, profluralin, prometon, propachlor, propazine, picloram, simazine, terbacil, trifluralin, trichlopyr, vernolate, etc.
Our specialists have in-depth experience in analyzing pesticide and herbicide in a range of matrices, including drinking water, wastewater, soils, sediments, aqueous samples, oils, and tissues. There are many advanced technologies that can be used:
- Advanced extraction techniques: Solid phase extraction (SPE), solid phase micro extraction (SPME), the salting–out assisted liquid–liquid extraction (SALLE) method, the vortex-assisted dispersive liquid–liquid microextraction (DLLME) method and more.
- Chromatographic or mass spectrometric techniques: Gas chromatography (GC) with electron capture detectors (ECD), liquid chromatography (LC), high performance liquid chromatography (HPLC) with UV detector, LC–MS/MS, HPLC–MS/MS, ultra HPLC–MS/MS (UHPLC–MS/MS), GC-MS/MS and gel permeation chromatography (GPC).
- Ability to analyze various types of pesticides and herbicides.
- Multiple reactions monitoring (MRM) available for high selectivity and sensitivity.
- Streamlined and simplified sample preparation procedures.
- High-quality report through use of library databases analysis for confirmatory.
