Loaʻa nā caps no nā'ōkuhi kīwaha i loaʻa me kahi puka ākea no ka weheʻana i ka autosampler e hoʻohana a me ka hoʻohuiʻana i ka papa inoa no ka mālamaʻana i ka sample. Ua hoʻohanaʻiaʻo Teflon a me Silini Rule a iʻole Ultra-Ultra-Matra-Ke hoʻohanaʻia e like me nā mea e pono ai keʻano o ka sucta E hōʻoia pono i nā hana maikaʻi loa, he kūpono ia no ka chromatography o ka chromatography, a e hōʻoia i ka hāʻuleʻole o ka septum i ke kaʻina hana injective.
Hoʻohanaʻia ke kaʻina hana e pili ana i ke kaʻina hana e hoʻohui ai i ka polytetrafluorlurolylethetyletheettyle a me ka silika silika i nā hiʻohiʻona maikaʻi loa o nā meaʻelua. ʻO ka polytetrafluorolyyuthethyletheylene tyerater o ka suittum composum e hoʻopiliʻia me ka hoʻoponopono houʻana. He mea kaumaha a me ke kauaʻana no Actid, Alkali, mahana, a me ka amenusion. ʻAʻole ia e hana pū me AcicED a me ka hoʻopiliʻana iā Alkali, a iʻole nā mea hao ikaika hoʻi i nā kiʻekiʻe kiʻekiʻe. I ka manawa like,ʻo ka elasticity o silicone sticone rubber a iʻole silicone e hiki ke hōʻoia i ka hanaʻana i ka hana.
