PCB apono ka ion trap mass analyzer i ka laina pahele ion ion, hana ʻia kāna electrode e PCB, a hoʻolālā ʻia kāna ʻāpana keʻa e huinahā. ʻO nā kumu o ka ʻae ʻana i kēia hoʻolālā penei: ʻo ka mea mua, ʻo ka ion ion trap ka mea i ʻoi aku ka nui o ka ion i hiki ke hoʻopaʻa ʻia ma mua o ka hei maʻamau ʻekolu-dimensional, no laila ʻoi aku ka kiʻekiʻe o ka ʻike i ka hoʻopili ʻana a me ka ʻike ʻana. ʻO ka lua, ʻo ka rectangle kekahi o nā geometric simplest i kūkulu ʻia, kahi kūpono loa no ka mīkini a me ka hoʻākoakoa. ʻO ke kolu, haʻahaʻa ka uku PCB, ʻenehana hana a me ke ʻano oʻo.

ʻO ka pahele ion PCB i ʻelua mau hui uila o PCB a me nā uila electrode cap electrode ʻelua. ʻO nā electrodes PCB āpau he 2.2 mm ka mānoanoa a 46mm lōʻihi. Hoʻohana ʻia ka ʻili o kēlā me kēia electrode PCB i ʻekolu mau ʻāpana: kahi electrode 40mm waena a ʻelua mau electrode hopena 2.7mm. Hana ʻia kahi lipine insulated 0.3mm ākea ma waena o ka electrode waena a me nā electrode hopena ʻelua i hiki i nā voltages hana like ʻole ke hoʻouka ʻia ma ka electrode waena a me nā electrodes hopena ʻelua. Hana ʻia nā puka hoʻonoho ʻehā me ke anawaena o 1mm ma nā electrodes ma nā wēlau ʻelua no ka ʻāpana pahele ion. Hana ʻia ka electrode uhi hope i ke kila kila me ka mānoanoa o 0.5 mm a hana ʻia i kahi ʻano kūikawā, no laila hiki ke hoʻohālikelike ʻia me nā puka hoʻonohonoho ma nā wēlau ʻelua o ka electrode PCB e hana i kahi pahele ion PCB.

Ke hana ka mea aniani papaha i ka paukū, hana ʻia ka uila radiofrequency i ka electrode waena o ka PCB e hana i kahi pā uila AC i hoʻopaʻa ʻia me ka uila, ʻoiai e hoʻopili ʻia ka voltage DC i nā electrode hopena ʻelua e hana i kahi pā uila DC i hoʻopaʻa ʻia. Hoʻomaʻamaʻa kahi puka me ke anawaena o 3mm i waenakonu o kēlā me kēia electrode cap end. Hiki i nā liona i hoʻokumu ʻia e nā kumu ion kūwaho ke komo i ka pahele ion ma o ka lua o ka electrode cap end, a hoʻopaʻa ʻia a mālama ʻia i ka pahele ion ma lalo o ka hana hui o ka radial AC i hoʻopaʻa ʻia i ka uila uila a me ka pā uila uila i hoʻopili ʻia DC. Hoʻohana ʻia kekahi o nā paʻa ʻelua o nā electrodes PCB i kahi kikowaena 0.8 mm ākea ma ke ʻano he ionion extraction channel, i hoʻohana ʻia no ka hoʻokaʻawale ʻana i nā ion i mālama ʻia i loko o ka pahele ion mai loko mai o ka hei no ka ʻike a me ke ʻano maikaʻi.
