Falanqaynta LCMS: Raad-raaca Phthalates ee Baijiu Shiinaha​

Sannadihii ugu dambeeyay, wasakhowga phthalate ee ku jira khamriga Shiinaha ee Baijiu (khamriga Shiinaha) ayaa si isdaba joog ah u soo jiidatay dareenka dadweynaha iyadoo ah walaac ku saabsan badbaadada cuntada. Isku-darka kiimikadan, kuwaas oo laga yaabo inay u guuraan khamriga, waxay keenaan khataro suurtagal ah oo ku yimaada caafimaadka aadanaha. Farsamooyinka kala duwan ee falanqaynta, Liquid Chromatography-Mass Spectrometry (LCMS) ayaa soo ifbaxay iyadoo ah qalab muhiim ah oo lagu raadraaco phthalates-ka Baijiu ee Shiinaha, sababtoo ah xasaasiyaddiisa sare iyo saxnaantiisa.

Phthalates: Waxyaabaha aan la rabin ee ku jira Baijiu Shiinaha​

Phthalates, ama phthalic acid esters (PAEs), waxaa badanaa loo isticmaalaa sidii balaastig-sameeyayaal. Baijiu-ga Shiinaha, waxay ka imaan karaan:

1. Ka guurista agabka baakadaha balaastikada ah;
2. Taabasho tuubooyinka balaastikada ah ama weelasha inta lagu jiro wax soo saarka;
3. Wasakheynta deegaanka ee maaddooyinka;

In kasta oo isticmaalka agabka balaastikada ah ee si toos ah loola xiriiriyo Baijiu-ga Shiinaha uu mamnuuc ka yahay xeerarka qaran, haddana socdaalka heerka raad-raaca ayaa weli ah walaac. Qaadashada xad-dhaafka ah ee phthalates-ka muddada dheer waxay carqaladeyn kartaa nidaamka endocrine-ka, iyadoo saameyn ku yeelan karta horumarka ilmaha iyo caafimaadka taranka.

LCMS: Baaraha Molecular ee Phthalates​

Chromatography-ga dareeraha ah - Spectrometry-ga cufnaanta (LCMS) wuxuu isku daraa awoodda kala-soocidda sare ee koromatography-ga dareeraha ah iyo xasaasiyadda sare ee spectrometry-ga cufnaanta, taasoo ka dhigaysa mid si gaar ah ugu habboon falanqaynta isku-dhafka raadadka ee matrices-ka adag sida Baijiu-ga Shiinaha. Faa'iidooyinka ugu muhiimsan waxaa ka mid ah:

• Xasaasiyadda Sare: Ogaanshaha ng/mL ama heerarka hoose;
• Xulasho sare: Aqoonsi sax ah iyo tirooyin phthalates badan;
• Waxtar sare: Falanqayn isku mar ah oo lagu sameeyo bartilmaameedyo badan oo hal duritaan ah;
• Awood xooggan oo ka hortagga faragelinta: Si wax ku ool ah ayay u yareysaa saameynta matrix-ka ee ka timaadda Baijiu-ga Shiinaha;

Socodka Shaqada LCMS ee Ogaanshaha Phthalate ee Baijiu Shiinaha​

1. Diyaarinta Muunad​

· Cirbad ama duritaan toos ah (muunado xoog yar leh);

· Isugeynta afuufidda Nitrogen-ka iyo is-weydaarsiga dareeraha;

1. Kala soocida Chromatography-ga dareeraha ah​

Iyada oo la adeegsanayo tiirka chromatography-ga marxaladda dib u celinta ee C18 oo leh methanol/biyo ama acetonitrile/biyo marxaladda guurguurta, qulqulka gradient-ka ayaa loo isticmaalaa in lagu kala saaro balaastikada kala duwan. Bartilmaameedyada ogaanshaha ee caadiga ah waxaa ka mid ah:

· Dimethyl phthalate (DMP)

· Diethyl phthalate (DEP)

· Dibutyl phthalate (DBP)

· Di (2-ethylhexyl) phthalate (DEHP)

1. Ogaanshaha Cabbirka Cufnaanta​

Ku hel qaabka ion-ka taban adigoo isticmaalaya isha ion-ka ee korontada ku shaqeeya (ESI) ama isha ion-ka kiimikada ee cadaadiska jawiga (APCI). Qalabka cabbiraha cufnaanta wuxuu hagaajiyaa xulashada iyo xasaasiyadda ogaanshaha iyada oo loo marayo habka la socodka falcelinta badan (MRM).

Xaqiijinta Habka iyo Xakamaynta Tayada​

Habka LCMS ee la isku halleyn karo wuxuu u baahan yahay xaqiijin adag:

• Kala duwanaanshaha toosan: Waxay daboolaysaa heerka la filayo iyadoo la adeegsanayo R² > 0.99；
• Xadka ogaanshaha/tirinta: Caadi ahaan heerarka hoose-μg/L, iyadoo la raacayo heerarka sharciyeynta;
• Saxnaanta iyo saxnaanta: Heerarka soo kabashada degdegga ah ee 85-115%, leexashada heerka qaraabada ah ee <15%;
• Gaar ahaanshaha: Waxay hubisaa in meelaha ugu sarreeya ee bartilmaameedku aysan faragelin lahayn;

Jawaabaha Warshadaha iyo Hagidda Macaamiisha​

Iyadoo la horumarinayo tiknoolajiyada ogaanshaha iyo xeerarka adag, warshadaha Baijiu ee Shiinaha waxay hirgeliyeen tallaabooyin lagu yareynayo khataraha phthalate:

1. Xakamaynta isha: Si tartiib tartiib ah uga bixidda qaybaha balaastikada ah ee wax soo saarka;
2. Maareynta habka: La socodka oo la xoojiyay iyo xakamaynta alaabta ceeriin ah;
3. Tijaabada ugu dambeysa ee badeecada: Nidaamyada kormeerka tayada adag;

Macaamiisha ahaan, waxaan sameyn karnaa waxyaabaha soo socda:

• Ka iibso noocyo sumcad leh iyada oo loo marayo kanaallo rasmi ah;
• Hubi daacadnimada baakadaha oo iska ilaali alaabada dhaawacan;
• Si habboon u kaydi, adigoo iska ilaalinaya heerkulka sare iyo kaydinta muddada dheer;

Aragtida Mustaqbalka​

LCMS waxay sii wadi doontaa inay door muhiim ah ka ciyaarto ogaanshaha phthalate ee Baijiu-ga Shiinaha. Horumarinta joogtada ah ee xasaasiyadda qalabka iyo hagaajinta habka ayaa suurtogalin doonta falanqayn dhakhso leh oo sax ah. Horumarinta hababka baaritaanka falanqaynta badan ayaa sii hubin doonta tayada dhammaystiran iyo hubinta badbaadada.
