Guard columns are typically chosen to have the same packing as the primary column.  PRP-X400 is packed in a small compact guard column for a semi-preparative\/preparative 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\u003eCation Exchange\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStationary Phase\u003c\/th\u003e\n\u003ctd\u003ePRP-X400\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\u003ePSDVB\/Sulfonic Acid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eParticle Surface Area (m2\/g)\u003c\/th\u003e\n\u003ctd\u003e8.25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePore Volume (cm3\/g)\u003c\/th\u003e\n\u003ctd\u003e0.0576\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\u003e400 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompound Classification\u003c\/th\u003e\n\u003ctd\u003eCarbohydrates\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\/hc-75-dry-resin\"\u003eHc 75 Dry Resin (Sds)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.hamiltoncompany.com\/knowledge-base\/application-note\/fermented-alcohol-detection-using-isocratic-cation-exchange-hplc\"\u003eFermented Alcohol Detection Using Isocratic Cation Exchange Hplc (Application Note)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.hamiltoncompany.com\/product-specs\/79917\"\u003e79917 (Specification)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hamilton Company","offers":[{"title":"Default Title","offer_id":46487172317263,"sku":"79917","price":1771.0,"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-hc-75-h-79917","provider":"danyel biotech","version":"1.0","type":"link"}
