| titleOfInvention | Filling method of small solid-phase extraction column with mixed packing, and small solid-phase extraction column |
| abstract | The invention discloses a filling method of a small solid-phase extraction column with mixed packing, and the small solid-phase extraction column. The filling method comprises the following steps: respectively weighing reverse-phase bonded silica gel adsorbent packing and/or inorganic substrate packing; evenly mixing in a rotary self-mixing mode and filling into the small column with a sieve plate; and fixing the sieve plate on the upper end of the packing. According to the method, the small solid-phase extraction column with the mixed packing is filled by using the dry method; and the multiple kinds of packing are evenly mixed in the rotary self-mixing mode before the column is filled, so that the packing can be evenly distributed in the small solid-phase extraction column; and the repeatability of the treated product is good. Therefore, the application range of the small solid-phase extraction column is enlarged, i.e., the small solid-phase extraction column can be used for adsorbing more kinds of impurities. The method is simple and convenient and easy in filling operation. The experiment shows that the small solid-phase extraction column prepared by using the method is higher in efficiency and resulted in fewer impurities in a filtering product. |
