HPLC & LC/MS Columns
Featured products
Generally, silica based columns are mechanically stable and provide high efficiencies, however, they cannot be used under alkaline conditions and their residual silanol groups tend to adsorb organic bases. InertSustain C18 employs a radically new type of silica, in which the surface of the silica is uniquely modified, enabling precise control of the silica properties.
InertSustain C18 inherits the advantages of all the current Inertsil HPLC columns (e.g., extremely low operating back pressure, superior inertness to typically any analytes, high efficiency and compatibility with a wide range of solvents), but now can be used for wide pH analysis with consistent performance from column to column and lot to lot.
Benefits
• High Inertness
• Extremely Low Operating Back Pressure
• Long Column Lifetime
• pH Range from 1 ～ 10
• Reliable Reproducibility

InertSustain AQ-C18 columns are designed to achieve strong retention for highly polar compounds, which is the most challenging goals in developing reversed phase methods. The optimization of bonding of the C18 groups at equal distance to the silica gel enable InertSustain AQ-C18 to offer significant retention for highly polar compounds even under water rich mobile phases.
Benefits
• Exceptional retention for highly polar compounds (hydrophilic)
• Highly inert packing material results in less tailing of peaks for virtually any type of analytes
• Extreme resistance to low and high pH mobile phases
• Reliable Reproducibility, performance & quality
• Endlessly reproducible from column-to-column and batch-to-batch

GL Sciences’ State-of-the-art HPLC Columns Technology
GL Sciences supports from the use of SPE to analysis. Among them all, HPLC columns which play a major role in separation analysis are manufactured by synthesizing base silica-gels, bonging phases and being packed into columns and through demanding tests for a stable supply with the same excellent quality all over the world. Based on accumulated know-how GL Sciences’ manufacturing technology keeps on evolving to supply better HPLC columns for customers.
Benefits
- Sophisticated self-manufacturing technology for the base silica - GL Sciences has been synthesizing base silica-gels, bonding phases and endcapping for column packing which enable us stable supply with exceptionally-high quality. Consequently those HPLC columns have been chosen for the method used for many years as reliable products.
- Reliable Column Performance
- Base Silica is Designed for Low Column Back Pressure to Reduce the Load on the System
- The Evolving HPLC Column Packings - GL Sciences has been steadily supplying with columns from Inertsil ODS, first-generation to InertSustain series, integration of state-ofthe-art technologies, and has established a very good reputation around the world. They are available with the same quality and the same performance anywhere in the world.
- Base on Evolutionally Surfaced Silica (ES Silica) evolved from Inertsil, InertSustain has developed. InertSustain employs a radically new type of silica , in which the surface of the silica is uniquely modified, the amount of silanols are controlled. Owing to this state-of-the-art technology ES silica allows easy surface modification including endcapping, which grants the following three benefits.
1. Exceptionally improved inertness 2. Robust bonded phase 3. High reproducibility batch to batch - Batch to Batch Reproducibility
