Tātaritanga LCMS: Te Aroturuki i ngā Phthalates i roto i te Baijiu Hainamana

I ngā tau tata nei, kua arohia te marea e te poke o te phthalate i roto i te Baijiu Hainamana (waipiro Hainamana) hei āwangawanga mō te haumaru kai. Ko ēnei matū, ka taea te heke ki roto i te waipiro, ka tū hei mōrearea ki te hauora o te tangata. I roto i ngā tikanga tātari maha, kua puta ake te Liquid Chromatography-Mass Spectrometry (LCMS) hei taputapu matua mō te whai i ngā phthalates i roto i te Baijiu Hainamana, nā tōna tairongo me te tika.

Phthalates: Ngā Tāpiringa Kāore e Hiahiatia i roto i te Baijiu Hainamana;

Ko ngā phthalates, ko ngā phthalic acid esters (PAEs) rānei, e whakamahia whānuitia ana hei hanga kirihou. I roto i te Baijiu Hainamana, ka ahu mai pea i:

1. Te hekenga mai i ngā rauemi takai kirihou;
2. Te whakapā atu ki ngā paipa kirihou, ki ngā ipu kirihou rānei i te wā e whakaputa ana;
3. Te poke o ngā kai i te taiao;

Ahakoa e aukatia ana te whakamahinga o ngā rauemi kirihou e pā tika ana ki te Baijiu Hainamana e ngā ture ā-motu, he āwangawanga tonu te hekenga o ngā rauemi kirihou iti noa iho. Mā te kai nui rawa o ngā phthalates mō te wā roa ka whakararuraru i te pūnaha endocrine, ka pā pea ki te whanaketanga o te tamaiti me te hauora uri.

LCMS: Te Kairangahau Irahiko mō ngā Phthalates;

Ka whakakotahi te Liquid Chromatography-Mass Spectrometry (LCMS) i te kaha wehewehe teitei o te wai chromatography me te aro nui o te papatipu spectrometry, ā, he tino pai mō te tātari i ngā matū iti i roto i ngā matrices matatini pērā i te Chinese Baijiu. Ko ngā painga matua ko:

• Te tairongo teitei: Te kitea i ngā kukū ng/mL, iti iho rānei;
• Te whiriwhiringa teitei: Te tautuhi tika me te ine i ngā phthalates maha;
• Teitei o te whai huatanga: Te tātaritanga i te wā kotahi o ngā whāinga maha i roto i te werohanga kotahi;
• Kaha te ātete-whakararuraru: Ka whakaiti i ngā pānga o te matrix mai i te Baijiu Hainamana;

Rerenga Mahi LCMS mō te Kitenga Phthalate i roto i te Baijiu Hainamana;

1. Te Whakarite Tauira;

·Te whakaranu, te werohanga tika rānei (mō ngā tauira iti te kukū);

·Te kukū o te hauota me te whakawhiti whakarewa;

1. Wehenga Chromatography Wai;

Mā te whakamahi i te pou chromatography āhua whakamuri C18 me te methanol/wai, te acetonitrile/wai ​​rānei hei āhua nekeneke, ka whakamahia te elution gradient hei wehewehe i ngā plasticizer rerekē. Ko ngā whāinga kitea noa ko:

·Dimethyl phthalate (DMP)

·Diethyl phthalate (DEP)

·Dibutyl phthalate (DBP)

·Di (2-ethylhexyl) phthalate (DEHP)

1. Te Kimi i te Ine Papatipu;

Kimihia i roto i te aratau katote kino me te pūtake katote rehu hiko (ESI) me te pūtake katote matū pēhanga hau (APCI). Ka whakapai ake te ine papatipu i te whiriwhiringa me te aro o te kimi mā te aratau aroturuki tauhohenga maha (MRM).

Whakamana Tikanga me te Mana Kounga;

Me whakamana pakari te tikanga LCMS pono:

• Awhe rārangi: Ka kapi i ngā kukū e tumanakohia ana me te R² > 0.99；
• Te rohe o te kitenga/te ine: I te nuinga o te wā kei raro iho i te μg/L ngā taumata, me te tutuki i ngā paerewa ture;
• Te tika me te tino tika: Ngā tere whakaora tere o te 85–115%, te paerewa rerekētanga <15%;
• Te Motuhaketanga: Kia kore ai e pokanoa ngā tihi ūnga;

Ngā Urupare a te Ahumahi me te Aratohu a te Kaihoko;

I te whanaketanga o te hangarau kimi me ngā ture pakari ake, kua whakatinanahia e te umanga Baijiu Hainamana ngā mahi hei whakaiti i ngā mōrearea phthalate:

1. Whakahaere pūtake: Te whakakore haere i ngā wāhanga kirihou i roto i te hanga;
2. Whakahaere tukanga: Te aro turuki me te whakahaere rauemi mata kua whakapai ake;
3. Whakamātautau hua mutunga: Ngā pūnaha tirotiro kounga pakari;

Hei kaihoko, ka taea e tātou te mahi i ēnei e whai ake nei:

• Hokona mai i ngā waitohu rongonui mā roto i ngā hongere mana;
• Tirohia te pono o te takai me te karo i ngā hua kua pakaru;
• Penapenahia kia tika, kia kore ai e nui te pāmahana me te rokiroki roa;

Ngā Tirohanga ā-Mārama;

Ka whai wāhi nui tonu te LCMS ki te kimi phthalate mō ngā Baijiu Hainamana. Mā te whakapai tonu i te aro o ngā taputapu me te arotau i ngā tikanga ka taea te tātari tere ake, tika ake hoki. Mā te whakawhanaketanga o ngā tikanga tātari maha-tātari ka whakarite kia tino whai hua te kounga me te haumaru.
