Low pH C18 HPLC Columns – Stable & High-Performance

LP-C18 HPLC Column

LP is abbreviation for Low pH. LP phases are designed for use at low pH conditions. LP phase consists of two very bulky hydrophobic protective groups to prevent siloxane bond from hydrolysis at low pH condition. So LP column is extremely stable in very low pH mobile phase and at high temperature, even at the lowest pH of 1.0, making it the most stable phase for low pH application in the market.Because it is not endcapped and has more surface silanols, LP phase has more retention for some early eluted polar compounds, and provides different selectivities.


Description

Features

1. Not endcapped, prevents siloxane bond from hydrolysis at low pH condition.

2. Compatible with 100% water as the mobile phase, more polar than “AQ”, better peak shape and resolution.

3. Best peak shape for polar compounds.

4. Exceptional lifetime at low pH (0.5-8.0) and high temperature.

5. LP-C18 is the most polar C18 among all the C18 products of Yicozoo.


How to choose C18 and LP-C18?

When pH<5.0, based on your separation conditions, you may choose either LP-C18 or C18;

When pH<2.0 (such as 0.1%TFA), LP-C18,which provides exceptional stability, longer lifetime, perfect peak shape and superior selectivity,it is your best choice
