Ekuhlaziyweni kwe-LC-MS, zonke izinyathelo zokulungiselela amasampula zibalulekile, ikakhulukazi ukukhetha nokusetshenziswa kwama-vial cap kanye ne-septa. Le ndatshana ifaka ngokuhlelekile amasu wokulungiselela asemqoka, kufaka phakathi ukuhlunga, i-protein yezulu, ukukhishwa kwesigaba esiqinile, ukukhishwa okuwuketshezi okuwuketshezi, ukukhishwa koketshezi okusekelwe. Ibuye ichaze nokuthi ungazikhetha kanjani i-Aijiren's Pre-slit PTFE \
abicone Septa, i-Senta ejwayelekile ye-Senta, kanye ne-Bonded Aluminium CAPS yokuhamba komsebenzi ohlukile ukuze uqinisekise uphawu oluvikelekile futhi uvikele ukuguquguquka nokungcola. Ngethebula lomkhiqizo wokuqhathanisa, abafundi bangaqonda ngokucacile izinzuzo nezimo zohlelo lokusebenza zohlobo lwe-cap \
septa, okwenza ukufezeka okukhulu nokunemba kwedatha ekuthuthukisweni kwemithi, ama-protemics kanye nokuhlolwa kwemvelo.
