Guard columns are typically chosen to have the same packing as the primary column. Any compounds or particulate material that would block the frits or highly adsorb to the primary column will do so on the guard column, thereby protecting and extending the lifetime of the more costly column. In addition to protective uses, guard columns can be used as sacrificial preparative components.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSeparation Mode\u003c\/th\u003e\n\u003ctd\u003eReversed-Phase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStationary Phase\u003c\/th\u003e\n\u003ctd\u003ePRP-C18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFormat\u003c\/th\u003e\n\u003ctd\u003eGuard Column\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHardware Inner Diameter\u003c\/th\u003e\n\u003ctd\u003e4.6 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHardware Length\u003c\/th\u003e\n\u003ctd\u003e33 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eParticle Size\u003c\/th\u003e\n\u003ctd\u003e12-20 µm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePacking Material Type\u003c\/th\u003e\n\u003ctd\u003ePS-DVB functionalized with C18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eParticle Surface Area (m2\/g)\u003c\/th\u003e\n\u003ctd\u003e368\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePore Volume (cm3\/g)\u003c\/th\u003e\n\u003ctd\u003e0.624\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGuard Column Size\u003c\/th\u003e\n\u003ctd\u003eSemiprep\/Preparative\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHardware Material\u003c\/th\u003e\n\u003ctd\u003eStainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax Pressure\u003c\/th\u003e\n\u003ctd\u003e5,000 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompound Classification\u003c\/th\u003e\n\u003ctd\u003eOrganics\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUOM\u003c\/th\u003e\n\u003ctd\u003e1 EACH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.hamiltoncompany.com\/knowledge-base\/guide\/hplc-reference-guide\"\u003eHplc Reference Guide (Guide)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.hamiltoncompany.com\/knowledge-base\/sds\/prp-c18-sds\"\u003ePrp C18 Sds (Sds)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.hamiltoncompany.com\/knowledge-base\/application-note\/spill-the-tea-catechins-identified-by-hamiltons-prp-c18\"\u003eSpill The Tea Catechins Identified By Hamiltons Prp C18 (Application Note)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.hamiltoncompany.com\/product-specs\/79918\"\u003e79918 (Specification)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hamilton Company","offers":[{"title":"Default Title","offer_id":46487172350031,"sku":"79918","price":1831.0,"currency_code":"ILS","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0712\/0748\/5519\/files\/HPLC_Stainless-Steel-Prep-Guard-Column_181004_165040.jpg?v=1787651509","url":"https:\/\/www.danyel.co.il\/products\/semiprep-preparative-guard-column-prp-c18-79918","provider":"danyel biotech","version":"1.0","type":"link"}
