在養蜂業中，磺胺類藥物是治療美國和歐洲臭蟲病（一種感染蜜蜂的疾病）的最常用抗生素。本應用說明介紹了QSight 200係統如何為蜂蜜中磺胺類藥物的分析提供一個非常靈敏和可靠的平台。
水溶性維生素（WSV）主要由維生素B複合物組成，是許多食品的基本成分，尤其是在嬰兒配方食品中。在分析強化食品時，由於需要符合每日的攝入量，維生素的濃度範圍很廣，這一點尤其具有挑戰性。本應用介紹了一種LC-MS/MS方法，用於嬰兒配方食品中B族維生素的高效、常規和穩定的色譜分析。很寬濃度範圍內的八種水溶性維生素被鑒定出來，並在4分鍾內定量。結果表明，保留時間重複性好，該方法能夠在0.5 ppb的濃度下檢測維生素B12，遠低於嬰兒配方奶粉中預期水平的約2 ppb。
抗生素在奶牛中被用於不同的治療，這會導致這些殘留物在牛奶中積累。人類食物中存在這種殘留物可能導致過敏反應、毒性反應，並產生耐藥菌株。為了保護消費者，歐盟監管機構發布了一些官方文件來監管獸藥。96/23/EC指令規定了食用動物的獸藥殘留控製。在印度，根據FSSAI（2018年7月20日的憲報公告）和EIC（水產養殖、雞蛋、蜂蜜、奶禽等的RMP）的規定，必須對抗生素進行分析。EIC和FSSAI都有動物食品基質中各種抗生素殘留的最大殘留限量（MRL）。考慮到安全性和防止消費者接觸獸藥，對牛奶進行磺胺類藥物殘留檢測至關重要。在這項工作中，我們提出了一種快速、靈敏的LC-MS/MS方法，用於定量分析牛奶 ...
獸藥在畜牧生產中用於治療疾病，預防感染和保護動物的生長，這有助於提供高質量的市場。然而，不加控製的使用可能會導致嚴重的人類疾病，因此世界各地的監管機構都製定了食品中獸藥的最大殘留量（MRL）或耐受量。由於樣品基質的複雜性和不同化學性質分析物的多樣性，獸藥殘留分析通常具有挑戰性。本研究中，采用溶劑萃取結合液相色譜-質譜聯用技術，建立了雞肉樣品中73種獸藥（包括13種不同化學類別）的快速、靈敏、選擇性分析方法。
以豬肉特有的三種肽為生物標誌物，建立了一種選擇性、靈敏的LC/MS/MS快速鑒定和分析肉樣的方法。優化後的樣品製備方法簡單易行，可用於生、熟、加工肉製品的分析。該方法可以在1%w/w（10mg/g）的閾值檢測範圍內選擇性地檢測各種食品豬肉中的肽，因此該方法可用於清真食品（或豬肉相關食品）樣品的分析。
最近在歐洲召回受汙染的雞蛋引起了對氟蟲腈中毒的嚴重健康擔憂。氟蟲腈是一種劇毒殺蟲劑，用於保護農作物。美國環保署已將氟蟲腈列為C組致癌物。在這項研究中，我們描述了一種快速、可靠的分析方法，采用爱游戏平台注册登录 QSight 200係列LC/MS/MS三重四極杆儀器對氟蟲腈及其代謝物進行鑒定。結果表明，該方法具有極佳的回收率、線性、重現性和超高靈敏度。三步法樣品製備過程快速簡便，LC/MS/MS分析時間可在6分鍾內完成，所有分析物的分離度都很高。
檢測大麻中農藥和真菌毒素的含量對於確保消費者安全和質量控製非常重要。在這項工作中，爱游戏平台注册登录 應用開發團隊分析了所有66種農藥（包括通常通過GC-MS/MS分析的極疏水性農藥和含氯農藥）以及加入到大麻花提取物中的5種真菌毒素，其含量遠低於加利福尼亞州規定的限值。使用配有ESI和APCI源的LC-MS/MS儀器，通過一種簡單的溶劑萃取方法，所有分析物回收率均在70-120%的可接受範圍內。
β-腎上腺素受體激動劑（β-激動劑）是一種用於治療哮喘等疾病的合成藥物，在生產食品的動物中也被用作生長促進劑。出於對人類健康的考慮，許多國家都禁止或管製在生產糧食的牲畜中使用β-激動劑。為了有助於監測和檢測牲畜體內的β-激動劑，本研究建立了一種高靈敏度和高選擇性的分析方法。采用LC/MS/MS方法詳細分析了豬肉樣品中的13種β-激動劑，並利用同位素標記的內標物來補償複雜食品基質中存在的基質效應。
真菌毒素是由真菌產生的有毒次級代謝產物，能引起人類和動物的疾病和死亡。樣品製備是成功分析食品基質中真菌毒素的關鍵步驟。“稀釋-進樣”法是一種快速簡便的將樣品引入LC/MS/MS分析的方法。然而，由於食品基質的複雜性，這種方法往往由於基質效應導致結果重複性很差。為了克服這些問題並提高靈敏度，本應用文獻詳細介紹了采用在線固相萃取（SPE）結合LC/MS/MS係統分析，用於樣品的富集和純化。
本文采用改良型QuEChERS 樣品前處理方法建立了牛奶中抗生素類多殘留UPLC MS/MS分析方法，該方法具有快速、穩定、可靠，高靈敏度和選擇性等特點。
本文采用超高效液相色譜 - 串聯質譜技術建立了燕窩中15 種激素類藥物含量的檢測，通過單次提取即可得到雌激素和孕激素化合物。
由於具有選擇性高、靈敏度高、適用於多種樣品基質中多種化合物的分析等優點，液相色譜-串聯質譜法（LC/MS/MS）已成為農藥分析的首選方法。本研究采用改進的QuEChERS提取法與LC/MS/MS聯用，建立了一種快速、靈敏、選擇性好的多殘留分析方法，對大米中200多種農藥進行了分析。采用QSight®三重四極杆質譜儀中的時間管理MRM™，可為目標分析物多個MRM通道自動分配最佳駐留時間。這不僅節約了方法開發的時間，也提高了數據質量和分析性能，這些在本研究中的大米樣品中多農藥殘留分析結果有具體展示。
液相色譜-串聯質譜（LC/MS/MS）已成為農藥檢測的首選方法。俄勒岡州對大麻花和大麻濃縮物中的59種農藥殘留量發布了監管限製，而其他州則提出了自己的與醫用大麻和大麻檢測有關的農藥殘留清單。
葡萄是世界上消費量最大的水果作物之一。葡萄既可作為新鮮產品也可作為加工產品消費，如葡萄酒、果醬、果汁、果凍、葡萄籽提取物、葡萄幹、醋和葡萄籽油。在葡萄的整個生長季節，各種各樣的殺蟲劑被使用以控製葡萄園的病蟲害和提高作物產量。由於大多數國家越來越嚴格的法規和安全標準，農藥殘留是葡萄產業利益相關者最為關注的問題。
