Description of Diol HPLC Columns

Hawach Scientific Co., Ltd Diol HPLC Column, the stationary phase is based on ultra-pure porous silica gel matrix, through the use of a unique fixed phase bonding technology, the use of 1, 2–dihydroxypropyl functional groups containing organosilane bonding. The Diol column is more stable than the traditional normal phase columns, such as NH2, SiO2.

A chromatographic column is a tube filled with packing material. HPLC column material is plastic, glass, stainless steel. The size mostly different in inner diameter, length of HPLC column tubes. There are many kinds of packing in the tube. Diol HPLC column packing is a silica gel matrix.
• 2,3-Dihydroxypropylsilane bonded silica gel stationary phase
• Diol HPLC columns commonly used chromatographic columns for normal phase analysis, reverse mobile phase can also be used
• High surface coverage

Advantage of Diol HPLC columns

Ultra inertness and high durability
Guaranteed reproducibility
Excellent separation rate and pressure
Reduce the influence of raw material silicone
More stable than the traditional normal phase columns, such as Silica, Amine.
Could be used in reverse phase analysis.
Similar polarity to Amino.
Good selectivity without excessive retention.
Improved peak shape versus bare silica.

Features of Diol HPLC columns

It can be used as a stationary phase of HILIC hydrophilic function chromatography
Improved peak shape versus bare silica.
Stability and reproducibility are good in positive phase columns

Applications of Diol HPLC columns

1. Suitable for most normal phase chromatography applications
2. The separation of organic acids and their polymers
