Raptor then evolved to bring that same improved speed, efficiency, and selectivity to UHPLC analyses by offering 1.8 \u03bcm particle columns. Learn more about Raptor LC columns at <a href=\"articles\/raptor-lc-columns&quot;\">www.restek.com\/raptor<\/a><\/p>\n\n\n\n<p>Even though every LC lab has a cache of C18s, not all C18s are created equal. Because the chemistry tends to be similar, the silica support that carries this ubiquitous octadecylsilane phase becomes vitally important. When you need a general-purpose LC column, don\u2019t just grab any C18. Choose the speed, efficiency, and long-lasting ruggedness of the Raptor C18 SPP LC column.<\/p>\n\n\n\n<p>The traditional end-capped Raptor 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, 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<h2 class=\"wp-block-heading\">Column Description:<\/h2>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-top is-layout-flow wp-block-column-is-layout-flow\"><style>.kb-image43718_623f7f-44.kb-image-is-ratio-size, .kb-image43718_623f7f-44 .kb-image-is-ratio-size{max-width:232px;width:100%;}.wp-block-kadence-column > .kt-inside-inner-col > .kb-image43718_623f7f-44.kb-image-is-ratio-size, .wp-block-kadence-column > .kt-inside-inner-col > .kb-image43718_623f7f-44 .kb-image-is-ratio-size{align-self:unset;}.kb-image43718_623f7f-44 figure{max-width:232px;}.kb-image43718_623f7f-44 .image-is-svg, .kb-image43718_623f7f-44 .image-is-svg img{width:100%;}.kb-image43718_623f7f-44 .kb-image-has-overlay:after{opacity:0.3;}<\/style>\n<div class=\"wp-block-kadence-image kb-image43718_623f7f-44\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"459\" height=\"1024\" src=\"https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr2246b-01-1-459x1024.jpg\" alt=\"\" class=\"kb-img wp-image-61678\" title=\"-\" srcset=\"https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr2246b-01-1-459x1024.jpg 459w, https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr2246b-01-1-135x300.jpg 135w, https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr2246b-01-1-768x1712.jpg 768w, https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr2246b-01-1-689x1536.jpg 689w, https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr2246b-01-1-919x2048.jpg 919w, https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr2246b-01-1-scaled.jpg 1149w\" sizes=\"auto, (max-width: 459px) 100vw, 459px\" \/><\/figure><\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h4 class=\"wp-block-heading\">Stationary Phase Category:<\/h4>\n\n\n\n<p>C18, octadecylsilane (L1)<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Ligand Type:<\/h4>\n\n\n\n<p>End-capped C18<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Particle:<\/h4>\n\n\n\n<p>1.8 \u03bcm, 2.7 \u03bcm, or 5 \u03bcm superficially porous particle (SPP or \u201ccore-shell\u201d particle) silica<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Pore Size:<\/h4>\n\n\n\n<p>90 \u00c5<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Surface Area:<\/h4>\n\n\n\n<p>125 m<sup>2<\/sup>\/g (1.8 \u03bcm),<br>130 m<sup>2<\/sup>\/g (2.7 \u03bcm),<br>or 100 m<sup>2<\/sup>\/g (5 \u03bcm)<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h4 class=\"wp-block-heading\">Recommended Usage:<\/h4>\n\n\n\n<p>pH Range: 2.0\u20138.0<br>Maximum Temperature: 80 \u00b0C<br>Maximum Pressure: 1034 bar\/15,000 psi* (1.8 \u03bcm),<br>600 bar\/8700 psi (2.7 \u03bcm);

The Raptor C18 was designed to build on that foundation, offering usability, peak symmetry, efficiency, and dependability\u2014with the unmatched reproducibility, speed, and reliability of a Raptor SPP LC column. Whether you are doing environmental, food safety, or bioanalytical work (Figures 5 and 6), you will finish your work faster if you choose the right column the first time.
