Buffer solutions prepared from these are typically utilized in reverse-phase high-performance liquid chromatography (RP-HPLC) when the sample forms acidic (oxonium ions (H\u003csub\u003e3\u003c\/sub\u003eO\u003csup\u003e+\u003c\/sup\u003e)) or basic (hydroxide ions (OH\u003csup\u003e−\u003c\/sup\u003e)) groups. Buffers mitigate the impact of oxonium and hydroxide ions, thus reducing pH fluctuations.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003c!-- Note --\u003e\n\n\n\u003c!-- Base product name --\u003e\n\n\u003c!-- DetailElements --\u003e\n\n\n\u003c!-- DeliveryText --\u003e\n\n\u003c!-- printCatalogLink --\u003e\n\u003c\/div\u003e\n\n\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv style=\"margin-top:1.5rem;\"\u003e\n  \u003ca href=\"https:\/\/www.carlroth.com\/medias\/SPEZ-256Y-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNjMzOHxhcHBsaWNhdGlvbi9wZGZ8YURkakwyZ3pZaTg1TWpVME5qQTBNREV6TlRrNEwxTlFSVnBmTWpVMldWOUZUaTV3WkdZfGVjNmM2ZjMyMmM4YWUyMzAwN2ZjODg4MDBjZmQzYTI1ZjNmMmMzZGQ3ZTM1OWViNjc0ZTE3ZjJjODQwMzM2MjY\" target=\"_blank\" rel=\"noopener noreferrer\" download style=\"display:inline-flex; align-items:center; gap:.65rem; text-decoration:none; color:#000; font-weight:600; font-size:1rem;\"\u003e\n    \u003csvg style=\"width:1.65rem;height:1.65rem;color:#dc2626;flex-shrink:0;\" viewbox=\"0 0 384 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" aria-hidden=\"true\"\u003e\n      \u003cpath d=\"M64 0C28.7 0 0 28.7 0 64V448c0 35.3 28.7 64 64 64H320c35.3 0 64-28.7 64-64V160H256c-17.7 0-32-14.3-32-32V0H64z\" fill=\"#ffffff\" stroke=\"currentColor\" stroke-width=\"32\"\u003e\u003c\/path\u003e\n      \u003cpath d=\"M256 0V128H384L256 0z\" fill=\"currentColor\"\u003e\u003c\/path\u003e\n      \u003ctext x=\"192\" y=\"380\" font-family=\"Arial, Helvetica, sans-serif\" font-size=\"110\" font-weight=\"bold\" fill=\"currentColor\" text-anchor=\"middle\"\u003ePDF\u003c\/text\u003e\n    \u003c\/svg\u003e\n    Technical Documentation (PDF)\n  \u003c\/a\u003e\n\u003c\/div\u003e","brand":"Carl Roth","offers":[{"title":"50 g \/ 1 piece","offer_id":56128397574476,"sku":"256Y.1","price":40.35,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 6+ pieces","offer_id":56128397607244,"sku":"256Y.1","price":38.33,"currency_code":"EUR","in_stock":true},{"title":"50 g \/ 24+ pieces","offer_id":56128397640012,"sku":"256Y.1","price":36.32,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 1 piece","offer_id":56128397672780,"sku":"256Y.2","price":98.4,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 6+ pieces","offer_id":56128397705548,"sku":"256Y.2","price":93.48,"currency_code":"EUR","in_stock":true},{"title":"250 g \/ 24+ pieces","offer_id":56128397738316,"sku":"256Y.2","price":88.56,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-HPLC-Salze-Gruppe_508d5800-c37f-4f05-bd68-a6b0c4695c7a.jpg?v=1766414047","url":"https:\/\/www.luminixhealth.com\/de-de\/products\/potassium-hydrogen-phthalate-256y-256y","provider":"Luminix Health","version":"1.0","type":"link"}
