Diol packing material can be universally used in different polar modes (NP, RP and HILIC). Diol bonded phases are a versatile alternative to unbonded silica for normal-phase separations with shorter equilibration times.
Ultra pure, spherical high performance HPLC phase based on silica gel
Diol, no endcapping, with 5 % carbon content
hydrophilic interaction
High-class HPLC phase perfectly suited to take on routine analyses as well as the most ambitious chromatography tasks, classical Diol phase without endcapping and 5 % carbon content, outstanding mechanical and chemical stability
Diol phase based on ultra-pure silica gel (purity > 99 %), metal content < 10 ppm, pH-stability 2 - 8, pore size 100 A, particle size 3 μm, 5 μm, 10 μm (15 μm, 20 – 45 μm on request)
Alternative to the silica packing with shorter equilibration time and comparable selectivity; due to the lower activity of these packings it can be also used for SEC-applications
Ultra pure, spherical high performance HPLC phase based on silica gel
Diol, no endcapping, with 3 % carbon content
Eurospher 100 Diol packing material can be universally used in different polar modes (NP, RP and IC). The Eurospher silica gel is modified by a dihydroxypropyl reagent. Compared to the Eurospher Si packing material, it is less polar and requires less equilibration time. The strength of Eurospher 100 Diol has been proven in the determination of tetracyclins and non-ionic surfactants.
Spherical high performance HPLC phase based on type A silica gel
Diol, no endcapping, with 8 % carbon content
ProntoSIL OH is a Diol bonded phase. The Diol packing is an alternative to the silica- packings. The equilibration time of the support is shorter in comparison to the corresponding silica support. The selectivities are comparable. Due to the lower activity of these packings they can also be used for SEC-applications. The OH bonding type is available in 120 Å and particle sizes of 3 μm and 5 μm.
