[1] Due to those concerns, much of the agricultural industry has largely replaced the traditional, toxic, solvent-based pesticides with the widely used, mostly less toxic, ionic pesticides. Collectively grouped into the category of \u201cIonic and Highly Polar Pesticides\u201d are herbicides, fungicides, defoliants, and desiccants. For traditional solvent-based pesticides, the regulatory test methods are typically gas and liquid chromatography combined with mass spectrometry.<\/p>\n<p>However, polar pesticides, which are ionic and non-volatile, are much more suitable for methods using ion chromatography (IC) separations combined with mass spectrometry (MS) detection. Consequently, determinations of anionic polar pesticide residues, such as glyphosate, glufosinate, and their degradation products, such as AMPA (aminomethyl)phosphonic acid), have been successfully demonstrated in beer, fruit, cereals, vegetables and drinking water by the Food Environmental Research Association (FERA, LTD) [2,3] and others [4-15] using IC with MS (tandem MS, high resolution accurate mass (HRAM) MS, or single quadrupole MS). Compared to the anionic highly polar pesticides, determinations of cationic polar pesticide residues have proven more challenging due to their similar chemical structures.<\/p>\n<p><a href=\"https:\/\/fei-online.com\/wp-content\/uploads\/sites\/4\/2022\/06\/thermofisher-App-Note_june2022.pdf\" target=\"_blank\" rel=\"noopener\">Click here for the whitepaper.<\/a><\/p>\n<\/div><\/section><br \/>\n<div  class='avia-image-container  av-styling-    avia-builder-el-7  el_after_av_textblock  el_before_av_social_share  avia-align-center '  itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\"  ><div class='avia-image-container-inner'><div class='avia-image-overlay-wrap'><a href='https:\/\/fei-online.com\/wp-content\/uploads\/sites\/4\/2022\/06\/thermofisher-App-Note_june2022.pdf' class='avia_image'   target=\"_blank\" ><img class='avia_image ' src='https:\/\/fei-online.com\/wp-content\/uploads\/sites\/4\/2022\/06\/mw-1.jpg' alt='' title='AN000607: Determination of cationic polar pesticides in cereals'  itemprop=\"thumbnailUrl\"  \/><\/a><\/div><\/div><\/div><br \/>\n<div  class='av-social-sharing-box  avia-builder-el-8  el_after_av_image  avia-builder-el-last  av-social-sharing-box-minimal '><div class='av-share-box'><h5 class='av-share-link-description av-no-toc '>Share this<\/h5><ul class='av-share-box-list noLightbox'><li class='av-share-link av-social-link-facebook' ><a target=\"_blank\" aria-label=\"Share on Facebook\" href='https:\/\/www.facebook.com\/sharer.php?u=https:\/\/fei-online.com\/determination-of-cationic-polar-pesticides-in-cereals-using-ion-chromatography-and-tandem-mass-spectroscopy\/&#038;t=Determination%20of%20cationic%20polar%20pesticides%20in%20cereals%20using%20ion%20chromatography%20and%20tandem%20mass%20spectroscopy' aria-hidden='false' data-av_icon='\ue8f3' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on Facebook' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on Facebook<\/span><\/a><\/li><li class='av-share-link av-social-link-twitter' ><a target=\"_blank\" aria-label=\"Share on Twitter\" href='https:\/\/twitter.com\/share?text=Determination%20of%20cationic%20polar%20pesticides%20in%20cereals%20using%20ion%20chromatography%20and%20tandem%20mass%20spectroscopy&#038;url=https:\/\/fei-online.com\/?p=10326' aria-hidden='false' data-av_icon='\ue8f1' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on Twitter' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on Twitter<\/span><\/a><\/li><li class='av-share-link av-social-link-whatsapp' ><a target=\"_blank\" aria-label=\"Share on WhatsApp\" href='https:\/\/api.whatsapp.com\/send?text=https:\/\/fei-online.com\/determination-of-cationic-polar-pesticides-in-cereals-using-ion-chromatography-and-tandem-mass-spectroscopy\/' aria-hidden='false' data-av_icon='\uf232' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on WhatsApp' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on WhatsApp<\/span><\/a><\/li><li class='av-share-link av-social-link-linkedin' ><a target=\"_blank\" aria-label=\"Share on LinkedIn\" href='https:\/\/linkedin.com\/shareArticle?mini=true&#038;title=Determination%20of%20cationic%20polar%20pesticides%20in%20cereals%20using%20ion%20chromatography%20and%20tandem%20mass%20spectroscopy&#038;url=https:\/\/fei-online.com\/determination-of-cationic-polar-pesticides-in-cereals-using-ion-chromatography-and-tandem-mass-spectroscopy\/' aria-hidden='false' data-av_icon='\ue8fc' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on LinkedIn' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on LinkedIn<\/span><\/a><\/li><li class='av-share-link av-social-link-mail' ><a  aria-label=\"Share by Mail\" href='mailto:?subject=Determination%20of%20cationic%20polar%20pesticides%20in%20cereals%20using%20ion%20chromatography%20and%20tandem%20mass%20spectroscopy&#038;body=https:\/\/fei-online.com\/determination-of-cationic-polar-pesticides-in-cereals-using-ion-chromatography-and-tandem-mass-spectroscopy\/' aria-hidden='false' data-av_icon='\ue805' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share by Mail'><span class='avia_hidden_link_text'>Share by Mail<\/span><\/a><\/li><\/ul><\/div><\/div><\/p><\/div><div class=\"flex_column av_one_fifth  flex_column_div av-zero-column-padding   avia-builder-el-9  el_after_av_three_fifth  avia-builder-el-last  \" style='border-radius:0px;
