Gukuramo Icyiciro Cyinshi (SPE) nicyitegererezo cyikoranabuhanga cyo kwitegura cyakozwe kuva hagati ya za 1980. Yatejwe imbere no kuvanga amazi-akomeye hamwe na chromatografiya. Ahanini ikoreshwa mugutandukanya, kweza no gukungahaza ingero. Intego nyamukuru nukugabanya intangarugero ya matrix no kunoza ibyiyumvo.

Ukurikije inyigisho ya chromatografiya yuzuye, tekinoroji ya SPE ikoresha adsorption yatoranijwe hamwe no gutoranya gutoranya kugirango itunganyirize, itandukanye kandi isukure ingero. Nibikorwa byo gukuramo umubiri harimo ibice byamazi kandi bikomeye; irashobora kandi kugereranywa no gufatwa nkibikorwa byoroshye bya chromatografique.
Igishushanyo mbonera cyibikoresho byo gukuramo icyiciro gikomeye
SPE ni ihame ryo gutandukanya chromatografiya yamazi ukoresheje adsorption yatoranijwe no guhitamo. Uburyo bukunze gukoreshwa ni ugutambutsa icyitegererezo cyamazi binyuze muri adsorbent, kugumana ibintu bigomba gupimwa, hanyuma ugakoresha imbaraga zingirakamaro kugirango usohokane umwanda, hanyuma uhite uhindura ibintu kugirango bipimishe hamwe na bike. solvent, kugirango tugere ku ntego yo gutandukana byihuse, kwezwa no kwibanda. Birashoboka kandi guhitamo adsorb ibangamira umwanda ukareka ibintu byapimwe bigasohoka; cyangwa kuri adsorb umwanda nibintu byapimwe icyarimwe, hanyuma ukoreshe umusemburo ukwiye kugirango uhitemo gutoranya ibintu byapimwe.
Gukuramo uburyo bukomeye bwo gukuramo ibyiciro birakomeye, kandi ihame ryakazi ryayo rishingiye ku kuba ibipimo bigomba gupimwa hamwe n’ibice bibangikanya bibangamira icyitegererezo cy’amazi bifite imbaraga zitandukanye ku gikorwa cyo gukuramo icyiciro gikomeye, ku buryo Bitandukanijwe. Igikoresho gikomeye cyo gukuramo icyiciro nicyuzuzo kidasanzwe kirimo C18 cyangwa C8, nitrile, amino nandi matsinda.
