Ma ke ao kiʻekiʻe o ka ultra-trace analysis (ppb\/ppt pae), nānā mākou i ka kemika kolamu a me ka ʻike kikoʻī nui, akā naʻe pinepine mākou i ka nānā ʻole i ka ʻili mua loa i hoʻopā ʻia e kā mākou hāpana: ka paia vial. No ka poʻe e holo ana i ka UHPLC-MS\/MS i loko o ka proteomics a i ʻole ka lāʻau toxicology, ʻaʻole he ipu wale ka hue aniani maʻamau - he pahele kemika ia e hiki ke hoʻopau i kāu hopena ma mua o ka hoʻoiho mua ʻana.

Ua ʻike paha ʻoe i nā hōʻailona: he 20% hāʻule ma kahi kiʻekiʻe ma muli wale nō o ka noho ʻana o kahi laʻana i loko o ka autosampler i ka pō, a i ʻole "nā piko ʻuhane" huhū ʻaʻole pono. ʻO ka hapa nui o ka manawa, ʻaʻole kāu mea hana ka mea hewa; ʻo ia nā kinetics silanol ma kāu ʻili aniani.

1. Ka Adsorption Headache: No ke aha Polar Analytes "Nalo"

ʻO ke aniani borosilicate maʻamau, ʻoi aku ka kiʻekiʻeKe aniani USP Type 1, mamao loa mai ka inert. Ke waiho nei ke kaʻina hana i ka ʻili e kolo ana me nā hui Silanol reactive (Si-OH).

ʻO ka Ion-Exchange Trap: Ma ka pH > 3, hoʻoneʻe ʻia nā silanols a lilo i ka hoʻoili ʻino. Inā ʻoe e hana me nā lāʻau lapaʻau maʻamau a i ʻole peptides, e hoʻopili lākou i ka paia aniani me ka paʻakikī ʻaʻole lākou e hiki i kāu mea ʻike.
Peak Tailing: ʻOiai ma ka pH haʻahaʻa, ʻo ka hoʻopaʻa ʻana o ka hydrogen ma waena o ke aniani a me kāu laʻana ke kumu i ka weliwelipeak tailing. ʻAʻole ʻoe e ʻike i ka manaʻo maoli; ke ʻike nei ʻoe i ka mea i koe ma hope o ka hue "ʻoki ʻia."

2. Vapor-Phase Silanization: The Only Real Deactivation

E poina i nā hue "wai-wai" makamae. ʻO ka uhi wai wai pinepine "puddles" ma lalo o ka hue—ma kahi e noho ai kāu mau microliters hope loa.

Ma Aijiren, hoʻohana mākou i ka Chemical Vapor Deposition (CVD). Hoʻopaʻa mākou i ke aniani me ke kinoea organosilane i loko o kahi ʻōpala i nā wela kiʻekiʻe.

ʻO ka "Invisibility Cloak": Hoʻokumu kēia kaʻina i kahi paʻa covalent paʻa, kūkulu i kahi pale kino e pale aku ai i kāu hāpana mai ka "ʻike" i ka lattice aniani reactive.
Zero Bleed: ʻO kēia ke kumu e koi ai ka poʻe loeaʻO nā hue HPLC Silani-ʻo ia wale nō ke ala e hōʻoia ai i ka laʻana āu e hoʻomākaukau ai ʻo ia ka laʻana like āu e hoʻokomo ai.

3. ʻIkepili Honua Maoli: LC-MS\/MS Recovery

Ma ka hōʻiliʻili ʻana, ʻo ka ratio Signal-to-Noise (S\/N) nā mea āpau. ʻAʻole ʻai wale nā kīʻaha sub-standard i kāu hōʻailona; leak lākou i nā ion e hoʻopōʻino i kāu papa kuhikuhi.

Manaʻo kōkua Lab Pro: hoʻohanaLC-MS\/MS no ka ho'āʻo lāʻau? ʻO ka Silanization kou pale maikaʻi loa i ka sodium (Na +) nā mea hoʻohui e hoʻopili i kāu spectra a hoʻopaʻa i kāu hōʻailona ion.

4. Mai hopu ʻia e ka "pH Drift"

ʻO ke aniani hoʻomaʻemaʻe ʻole e hoʻolei i nā ion metala alkali. No nā analytes koʻikoʻi e like menā catecholamine a i ʻole esters, hoʻomaka kēia hoʻololi i ka hoʻohaʻahaʻa wikiwiki. Inā noho kāu laʻana i ka pila, ʻo ia ke kuke ʻana i kona ʻano alkaline ponoʻī. Hoʻopaʻa maikaʻi ka Silanization i ka matrix aniani.

5. I ka manawa hea ʻaʻole hiki ke kūkākūkā?

ʻAʻole pono ʻoe i ke aniani silanized no kēlā me kēia holo maʻamau. Akā pono ʻoe inā:

He <1 μg\/mL ka helu ʻana: He mea make nā poho adsorption ma kēia mau pae.
Ke hoʻohana nei ʻoeLC-MS Vials: E hōʻemi i nā piko uhane a me ka hoʻopau ʻana i ka ion.
Ke hoʻohana neiHoʻokomo Micro: He nui ka ratio surface-to-volume ma ʻaneʻi—inā ʻeleu ke aniani, ua pau kāu hāpana.
Ka waihona me4mL waihona waihona: Pono ke kūpaʻa lōʻihi i ke kūʻokoʻa kemika.

ʻO ka laina lalo o Aijiren

ʻAʻole mākou i kūkulu wale i kahi hue; ua hana mākou i kahi kaiapuni paʻa no kāu kemika.

2mL ʻO nā hue Silani: Hoʻoponopono pololei ʻia no Agilent, Waters, a me Shimadzu.
Hoʻopau ʻia i hōʻoia ʻia: Zero siloxane bleed i kāu pae kelepona.
Hōʻoia ʻia ka Hydrophobicity: Hoʻāʻo ʻia kēlā me kēia pūʻulu pili pili no ka uhi paʻa.

E oki i ka nalowale ʻana i kāu mau laʻana - Noi i kahi pahu pahu Silanised manuahi i kēia manawa

Mua:

Hoʻomaʻemaʻe a me ka hoʻohana hou ʻana i ke poʻo: ke kaʻina hana, ka hoʻohālikelike ʻana i ke kumu kūʻai o nā vial hiki ke hoʻohana hou ʻia.
