Ultisil LP-C8
– 54 columnsLP is abbreviation for Low pH. LP phases are designed for use at low pH condition. LP phase consists of two very bulky hydrophobic protective groups to prevent siloxane bond from hydrolysis at low pH condition. So the LP column is extremely stable in very low pH mobile phase and at high temperature, even at the lowest pH 1.0, making it the most stable C18 for low pH application in the market. Because LP phase is not endcapped and has more surface silanols, LP phase has more retention for some early eluted polar compounds, and provides some different selectivity than traditional C18. LP-C18 is the most polar C18 among all the C18 products of Welch.
- The characteristics of LP Columns: LP-C18 and LP-C8
- Not end-capped
- Endure 100% water as the mobile phase
- Best peak shape for polar compounds analysis
- Exceptional lifetime at low pH (1.0-8.0)
