Abstract
Description
The present invention relates to a method for producing end capping filler, a filler and a fill column manufactured using the same, and more particularly to a method for manufacturing an end capping filler excellent in acid resistance and a filler and a fill column manufactured using the method.
Reversed phase chromatography fillers, in which functional groups are hydrocarbon based, are mostly used as silica gel fillers for HPLC. However, these fillers irreversibly interact with ionic compounds, especially basic compounds, and when used under strong acidic conditions, the durability of the column is rapidly deteriorated There is a problem such as. In particular, the effects are more pronounced when they are used for analyzing or sorting compounds such as peptides, proteins and nucleic acid bases.
It is known that the irreversible interaction is caused by silanol groups remaining after the reaction and trace amounts of metal ions remaining in the silica gel matrix (see Non-Patent Documents 1 and 2). In recent years, the purity of the silica gel for chromatography has been considerably improved, so that the effect on the coordination compound produced by the metal ion of the silica gel is considerably reduced.
One of the most well-known general methods is to add an organic base such as pyridine and reflux in a toluene solvent to remove the residual silanol groups. Trimethylchlorosilane (hereinafter referred to as 'TMS') (see Non-Patent Documents 3 and 4).
In addition, a method of reacting in a gas phase (see Patent Document 1) and a method of reacting in a supercritical fluid (see Patent Document 2 ) Are known. It is also known that two different kinds of organic bases are used for the reaction and the endcapping is divided into two or more times (see Patent Document 3).
As described above, many end capping methods have been disclosed, but a lot of reaction reagents, especially silylation reagents (see Non-Patent Document 6), have been much more.
Further, after C18 is bonded to the silica gel, TMS and hexamethyldisilazane (hereinafter referred to as "HMDS") are added at the same time to perform secondary end capping, and then TMS is used for the tertiary end capping (see Patent Document 4 ), Or a method in which end-capping is carried out in a gas phase using cyclosiloxane or HMDS at a temperature of 250 ° C or higher (see Patent Document 5).
Although there are many HPLC fillers prepared with the endcapping process disclosed in this prior art, it is difficult to say that any of the methods completely endcapped the remaining silanol groups. End capping is performed by dimethylsilylation of the silanol groups on the silica gel surface using TMS, HMDS, and cyclosiloxanes crosslinked at high temperatures, which are used as endcapping reagents. However, in practice, end capping of all silanol groups takes into consideration the three- It is difficult to see.
