摘要： The invention relates to a porous silica having an average pore diameter in the range of from 20 to 450 Å, a median (D50) pore diameter in the range of from 20 to 450 Å, a pore volume in the range of from 0.15 to 1.2 cm 3 g -1 , a surface area in the range of from 100 to 600 m 2 g -1 , and a span of 0.80 or less.
The invention also relates to a method of producing a porous silica, in which an aqueous phase comprising nanoparticulate silica and an organic phase are mixed together to form a water-in-oil dispersion or emulsion, in which the organic phase comprises an organic solvent that is insoluble or partially soluble in water, and optionally also a non-polar organic compound that is insoluble in water and at least partially soluble in the organic solvent, wherein a gelling agent is present in the aqueous phase such that the nanoparticulate silica gels to form a porous silica.-

摘要： The invention relates to silica particles having a fine pore size of 1 to 250 Angstrom (Å) and comprising a silane group which comprises two groups which are each independently selected from the group consisting of alkyl, aryl, alkylaryl, heteroalkyl, heteroaryl, and heteroalkylaryl. The present invention further relates to a method of preparing such silica particles as well as the use of such silica particles as stationary phase for purifying a modified conjugated peptide, such as a GLP-1 agonist or a GLP-2 analog.

摘要： The invention relates to a porous silica with a median pore diameter of 210 Å to 500 Å, and with a pore volume of 0.80 cm 3 g -1 to 1.2 cm 3 g -1 . The invention also relates to a method of producing a porous silica, in which a liquid phase-dispersed nanoparticulate silica is gelled in the presence of either (i) a Bronsted acid and an amine compound having two or more primary or secondary amine groups or (ii) an amino acid.
The invention further relates to the use of the porous silica as a stationary phase for separation, and also to a separation column or vessel containing the porous silica.-
