Raptor then evolved to bring that same improved speed, efficiency, and selectivity to UHPLC analyses by offering 1.8 \u03bcm particle columns.

Designed and intended specifically for use on LC-MS\/MS systems, 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 (MS). 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<div class=\"wp-block-custom-chromatogram-article-top\"><div class=\"chromatogram-article-placeholder\"><div class=\"figure-heading\"><\/div><div class='chromatogram-article-inner-full'><div class=\"chromatogram-article-inner\">\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-905c269e wp-block-columns-is-layout-flex\" style=\"padding-right:20px;padding-left:20px\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><style>.kb-image43716_12e0e7-ca.kb-image-is-ratio-size, .kb-image43716_12e0e7-ca .kb-image-is-ratio-size{max-width:190px;width:100%;}.wp-block-kadence-column > .kt-inside-inner-col > .kb-image43716_12e0e7-ca.kb-image-is-ratio-size, .wp-block-kadence-column > .kt-inside-inner-col > .kb-image43716_12e0e7-ca .kb-image-is-ratio-size{align-self:unset;}.kb-image43716_12e0e7-ca figure{max-width:190px;}.kb-image43716_12e0e7-ca .image-is-svg, .kb-image43716_12e0e7-ca .image-is-svg img{width:100%;}.kb-image43716_12e0e7-ca .kb-image-has-overlay:after{opacity:0.3;}<\/style>\n<div class=\"wp-block-kadence-image kb-image43716_12e0e7-ca\"><figure class=\"aligncenter size-medium_large\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"2125\" src=\"https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr1970e-01-768x2125.jpg\" alt=\"\" class=\"kb-img wp-image-61766\" title=\"-\" srcset=\"https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr1970e-01-768x2125.jpg 768w, https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr1970e-01-108x300.jpg 108w, https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr1970e-01-370x1024.jpg 370w, https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr1970e-01-555x1536.jpg 555w, https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr1970e-01-740x2048.jpg 740w, https:\/\/discover.restek.com\/wp-content\/uploads\/article-ligand-gnbr1970e-01-scaled.jpg 925w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><\/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>Sterically protected 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 silica (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: 1.0\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);

Ruggedness and repeatability are essential, which is why from the silica and the bonding technique, to the packing process and upgraded hardware, every decision that went into creating this column was made to ensure superlative reproducibility, from injection to injection (Figure 2) and from lot to lot (Figure 3). We also adopted new quality control (QC) specifications to guarantee the retention time stability you need for worry-free analyses.<\/p>\n\n\n\n<p>One of the greatest advantages of an SPP column is the ability to operate at higher linear velocities without losing efficiency as you would with a conventional fully porous particle column. But, these higher velocities can also generate higher backpressures that rob you of performance. Like all Raptor columns, our ARC-18 can handle increased pressures and handle them longer than other manufacturers\u2019 SPP columns, to help you achieve <em>Selectivity Accelerated<\/em> while offering outstanding reproducibility and maintaining efficiency\u2014even in aggressive MS conditions.<\/p>\n\n\n<div class=\"wp-block-custom-chromatogram-article-top\"><div class=\"chromatogram-article-placeholder\"><div class=\"figure-heading\"><strong>Figure 2:<\/strong>\u00a0Even after hundreds of injections with a highly acidic mobile phase like 0.2% formic acid, a Raptor ARC-18 column will provide consistent, reliable data.<\/div><div class='chromatogram-article-inner-full'><div class=\"chromatogram-article-inner\">\n<style>.wp-block-kadence-advancedheading.kt-adv-heading43716_f2c06e-f9, .wp-block-kadence-advancedheading.kt-adv-heading43716_f2c06e-f9[data-kb-block=\"kb-adv-heading43716_f2c06e-f9\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-heading43716_f2c06e-f9 mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-heading43716_f2c06e-f9[data-kb-block=\"kb-adv-heading43716_f2c06e-f9\"] mark.kt-highlight{font-style:normal;color:#f76a0c;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-heading43716_f2c06e-f9 img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-heading43716_f2c06e-f9[data-kb-block=\"kb-adv-heading43716_f2c06e-f9\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<h3 class=\"kt-adv-heading43716_f2c06e-f9 wp-block-kadence-advancedheading\" data-kb-block=\"kb-adv-heading43716_f2c06e-f9\">After 500 injections,&nbsp;pesticide compounds&nbsp;are well within narrow,&nbsp;15-second MRM&nbsp;windows!<\/h3>\n\n\n<div class=\"wp-block-custom-chromatogram-article\"><div class=\"wp-block-custom-chromatogram-article\"><div class=\"chromatogram-image regular-image\"><img decoding=\"async\" src=\"https:\/\/ez.restek.com\/images\/cgram\/lc_ff0553.png\" alt=\"LC Multiresidue Pesticide Standard #1 on Raptor\u2122 ARC-18 for Injection Reproducibility\" title=\"-\"><\/div><p class=\"article-id\" style=\"text-align:center\"> LC_FF0553<\/p><div class=\"chromatogram-conditions\"><h4>Conditions<\/h4><div class=\"conditions-container container-fluid\"><div class=\"row\"><table class=\"conditions col-lg-6 col-12\"><tr><th class=\"conditions_header\" scope=\"row\">Column<\/th><td>Raptor\u2122 ARC-18  (<a target=\"_blank\" href=\"https:\/\/www.restek.com\/p\/9314A12?utm_source=chromatograms&amp;utm_medium=link&amp;utm_campaign=LC_FF0553\" rel=\"noopener\">cat.# 9314A12<\/a>)<\/td><\/tr><tr><th class=\"sub conditions_header\" scope=\"row\">Dimensions:<\/th><td>100 mm x 2.1 mm ID<\/td><\/tr><tr><th class=\"sub conditions_header\" scope=\"row\">Particle Size:<\/th><td>2.7 \u00b5m<\/td><\/tr><tr><td><\/td><tr><th class=\"sub conditions_header\" scope=\"row\">Temp.:<\/th><td>50 \u00b0C<\/td><\/tr><tr class=\"cgram_header_row\"><th class=\"conditions_header\" scope=\"row\">Standard\/Sample<\/th><td>LC multiresidue pesticide standard #1 (<a target=\"_blank\" href=\"https:\/\/www.restek.com\/p\/31972?utm_source=chromatograms&amp;utm_medium=link&amp;utm_campaign=LC_FF0553\" rel=\"noopener\">cat.# 31972<\/a>)<\/td><\/tr>\n<tr><th class=\"sub conditions_header\" scope=\"row\">Diluent:<\/th><td>Water<\/td><\/tr><tr><th class=\"sub conditions_header\" scope=\"row\">Conc.:<\/th><td>20 ng\/mL<\/td><\/tr><td><\/td><\/tr><tr><th class=\"sub conditions_header\" scope=\"row\">Inj.
