{"product_id":"uhplc-guard-columns-nucleodur-38kp-38kp","title":"UHPLC Guard Columns NUCLEODUR®, Phenyl-Hexyl, 1.8µm, 4x2mm, 3 unit(s)","description":"\u003cp\u003eUHPLC Guard Columns NUCLEODUR® Phenyl-Hexyl provide front-end protection for ultra-high-performance liquid chromatography systems. This configuration uses a phenyl-hexyl bonded phase on 1,8 µm particles within a 4 x 2 mm body and is supplied in packs of 3 pc(s). The fine particle diameter is aligned with UHPLC operating pressures and flow regimes, helping to retain the efficiency of the downstream analytical column while trapping debris and strongly adsorbed sample constituents. Phenyl-hexyl selectivity supports π–π and hydrophobic interactions that are frequently exploited for aromatic and moderately polar compounds. Compact dimensions allow the guard cartridge to be mounted in compatible holders without excessive extra-column volume. These NUCLEODUR® units from manufacturer MACHEREY-NAGEL are intended for laboratories that already run phenyl-hexyl UHPLC methods and wish to extend analytical-column lifetime through routine guard replacement. The three-piece pack supports continuous operation and scheduled maintenance in high-throughput chromatographic environments.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article belongs on \u003ca href=\"\/en-fr\/collections\/hplc-guard-columns\"\u003eHPLC guard columns\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/hplc-columns-and-accessories\"\u003eHPLC columns \u0026amp; accessories\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 3 pc(s)\u003c\/li\u003e\n\u003cli\u003eType: UHPLC guard column\u003c\/li\u003e\n\u003cli\u003eBrand: NUCLEODUR®\u003c\/li\u003e\n\u003cli\u003eStationary phase: Phenyl-Hexyl\u003c\/li\u003e\n\u003cli\u003eParticle size: 1,8 µm\u003c\/li\u003e\n\u003cli\u003eDimensions: 4 x 2 mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Macherey-Nagel","offers":[{"title":"3 pc(s) \/ 1 piece","offer_id":56151553474892,"sku":"38KP.1","price":167.7,"currency_code":"EUR","in_stock":true},{"title":"3 pc(s) \/ 6+ pieces","offer_id":56151553507660,"sku":"38KP.1","price":159.32,"currency_code":"EUR","in_stock":true},{"title":"3 pc(s) \/ 24+ pieces","offer_id":56151553540428,"sku":"38KP.1","price":150.93,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/HPLC-NUCLEODUR-Vorsaeulen-3-1000Wx1000H_8da80159-1d73-4e12-a962-81ab4df3cbba.jpg?v=1766437229","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/uhplc-guard-columns-nucleodur-38kp-38kp","provider":"Luminix Health","version":"1.0","type":"link"}
