A premium inert coating applied to the stainless-steel surface of our LC columns reduces nonspecific binding of chelating analytes, enabling sensitive analysis and smooth integration of peaks. Combined with Restek\u2019s selective stationary phases, these new inert LC columns are ideal for the analysis of metal-sensitive compounds, such as organophosphorus pesticides and mycotoxins.<\/p>\n\n\n\n<p>Restek\u2019s inert LC columns provide four key benefits:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Improved peak shape<\/strong> without passivation or mobile phase additives.<\/li>\n\n\n\n<li><strong>Increased response and analyte recovery,<\/strong> allowing lower detection limits.<\/li>\n\n\n\n<li><strong>High accuracy and throughput<\/strong> with less variability.<\/li>\n\n\n\n<li><strong>Less time-consuming conditioning<\/strong> and complicated passivation required.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Exceptional Inertness Brings Exceptional Performance<\/h2>\n\n\n\n<p>Analyzing compounds that have nonspecific adsorption (NSA) or nonspecific binding (NSB) to metal surfaces in LC columns has historically been a challenge. Poor peak shape and sensitivity are key indicators that polar, usually acidic, compounds are interacting with the metal surfaces in the column, causing poor data quality. Our premium inert column technology is designed to eliminate NSA and NSB of active analytes to the column hardware, giving analysts greater confidence in their data when working with metal-sensitive analytes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Pair Your Inert LC Column with an Inert Guard Column for Even Greater Benefits<\/h2>\n\n\n\n<p>Available in a variety of stationary phases, our inert guard columns provide optimal protection to your LC column and system while also reducing nonspecific binding of chelating analytes. Our standalone guard columns can be used in&nbsp;conjunction with any LC column and are specifically designed to complement and enhance the performance of our inert columns. Go to page 11 to see the improved performance when using an inert LC column and guard compared to a&nbsp;conventional stainless-steel column and guard.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">An Extensive Product Line to Meet Your Unique Needs<\/h2>\n\n\n\n<p>Restek\u2019s inert LC column technology is available in various column types to accommodate a wide range of applications and testing methodologies. Our inert columns are now available for the following phase types: Raptor Biphenyl, Raptor C18, Raptor ARC-18, Force Biphenyl, and Force C18. The following columns are recommended for these specific applications:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Inert LC Column<\/strong><\/td><td><strong>Application<\/strong><\/td><\/tr><tr><td>Raptor Inert ARC-18<\/td><td>Pesticides<\/td><\/tr><tr><td>Raptor Inert Biphenyl<\/td><td>Mycotoxins<\/td><\/tr><tr><td>Force Inert C18<\/td><td>Methylmalonic acid<\/td><\/tr><tr><td>Raptor Inert C18<\/td><td>Veterinary Drugs<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Pesticides<\/h3>\n\n\n\n<p>Pesticide panels benefit from the use of inert LC columns as they contain a wide variety of compounds. Phosphorylated, acidic, polar compounds, and\/or metal chelating species, such as organophosphate pesticides, are reactive to the metal surfaces inside of the analytical column. Our new inert LC columns solve that problem easily to improve the overall performance of your pesticide panel.<\/p>\n\n\n<div class=\"wp-block-custom-chromatogram-article-top\"><div

In this mycotoxin analysis, we assessed the improvements in analyte recovery and peak shape when utilizing an inert LC column and guard compared to a conventional stainless-steel column and guard. Figure 9 shows the relative peak height increase when switching from a stainless-steel column and guard to an inert column and guard, with increased recoveries in almost all compounds, most notably in the critical fumonisin B1, B2, and B3 compounds.

It is particularly adept at separating compounds that are hard to resolve or that elute early on C18 and other phenyl chemistries.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Raptor Inert C18<\/strong><\/h4>\n\n\n\n<p>This traditional end-capped C18 offers the highest hydrophobic retention of any Raptor phase, and it is compatible with a wide range of mobile phases from moderately acidic to neutral (pH 2\u20138). Whether for food safety or environmental or bioanalytical analyses, this phase offers consistently excellent data quality in less time across myriad reversed-phase applications, matrices, and compound classes.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Raptor Inert ARC-18<\/strong><\/h4>\n\n\n\n<p>The Raptor ARC-18 column features a well-balanced retention profile without the drawbacks of using an ordinary C18 in the harsh, acidic mobile phases needed for mass spectrometry. Even after extended use in these low-pH (\u2264 2.0) conditions, the sterically protected ARC-18 offers consistent retention, peak shape, and response for charged bases, neutral acids, small polar compounds, and more.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Force LC Columns<\/h3>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-medium\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"89\" src=\"https:\/\/discover.restek.com\/wp-content\/uploads\/logo-Force-300x89.jpg\" alt=\"\" class=\"wp-image-28314\" title=\"-\" srcset=\"https:\/\/discover.restek.com\/wp-content\/uploads\/logo-Force-300x89.jpg 300w, https:\/\/discover.restek.com\/wp-content\/uploads\/logo-Force-768x228.jpg 768w, https:\/\/discover.restek.com\/wp-content\/uploads\/logo-Force.jpg 929w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/figure>\n<\/div>\n\n\n<p>Force fully porous particle (FPP) LC columns are designed and manufactured to handle high-pressure, high-stress conditions.
