Eight water soluble vitamins over a wide concentration range were identified and quantified in under four minutes. The results showed excellent retention time repeatability and the method was able to detect vitamin B12 at 0.5 ppb, well below the expected level of ~2 ppb in infant formulas.

Since 2003 the usage of azo and non-azo dyes for food coloring has been declared as illegal by many of the food international authorities across the globe. That is because these substances such as Sudan I,II,III,IV and Rhodamine B, are potentially carcinogens and genotoxin in nature. As of now, no official methods have been published for the detection of illegal dyes however, the most used analytical technology is GC-MS or HPLC coupled with UV or MS detection.

Fipronil is a broad-spectrum phenylpyrazole insecticide almost used to protect corps from insects but also to treat lice and ticks in chickens. The U.S. EPA classified fipronil as Group C, possible human carcinogen, therefore International organizations defined admissible limits for the fipronil usage which in egg is of 5 µg/L4. LC-MS/MS technology can provide a robust and reliable method to detect such a contaminant in food.

Aflatoxin B1 is often found in animal feeds such as corn, cottonseed cake, groundnut meal, and other agricultural commodities. When these contaminated feeds are ingested by milk-producing animals, such as cattle, aflatoxin B1 can be converted to aflatoxin M1 (a hydroxy derivate of aflatoxin B1) by oxidation metabolism, and then excreted in milk. To protect consumers from the potential toxicity and carcinogenicity of aflatoxin M1, regulatory agencies have established regulatory limits or action levels for aflatoxin M1 in milk products.

In this study, a simple, fast, selective and sensitive LC/MS/MS method for the analysis of aflatoxin M1 is presented, along with the evaluation of three sample preparation methods.

Coumarin (1,2-benzopyrone) occurs as a natural component in some plants, and is utilized as a flavoring ingredient in some foods, tobaccos and cosmetic products. In recent years, coumarin has been added to electronic cigarette liquid nicotine solutions as a flavoring component, producing a complex flavor profile with aromas of vanilla, almond, cherry and cinnamon. Coumarin has been found to exhibit hepatoxic effects, and has been banned by the FDA in food products, but this ban does not extend to tobacco products, such as electronic cigarettes.

This application note details a method for the analysis of coumarin in electronic cigarette liquid nicotine cartridges, utilizing PerkinElmer UHPLC system coupled to a QSight® 220 triple quadrupole mass detector with a dual ionization source.

Polycyclic aromatic hydrocarbons (PAHs) can contaminate foods during smoking, heating, and drying processes that allow combustion products to come into direct contact with food. They can also enter food supply chains through contaminated air and water, and accumulate in various food chains. Regulations are in place to monitor PAHs levels in foods; the EU set a stringent maximum residue limit (MRL) for BaP in muscle meat of smoked fish and smoked fishery products at 2 µg/kg.2 In this study, seafood samples were prepared using a QueChERS extraction method followed by a dispersive solid-phase extraction clean-up step. The samples were subsequently analyzed by coupling a UHPLC system with a triple quadrupole mass spectrometer.

In apiculture, sulfonamides are the most commonly used antibiotics to treat American and European Foulbrood, a type of disease that infects bees. This application note demonstrates how QSight 200 System can provides a very sensitive and robust platform for the analysis of sulfonamides in honey.

Antibiotics are used in dairy cattle for different treatments, but it leads to accumulation of these residues in milk. Presence of such residues in human food can be responsible for allergic reactions, toxic effects and develops resistant strains of bacteria. To protect consumers, regulatory agencies in the European Union published several official documents to regulate the control of veterinary drugs. Council Directive 96/23/EC establishes the veterinary residue control in food producing animals. In India, as per FSSAI (gazette notification dated 20th July 2018) and EIC (RMP for Aquaculture, Egg, Honey, Milk Poultry etc.) it is a mandate to do the analysis of antibiotics. EIC and FSSAI both have maximum residue limits (MRLs) for various antibiotic residues for food matrices from animals. It is essential to test milk for residues of sulfonamides considering safety and prevent exposure of consumers to veterinary drugs. In this work, we present a fast and sensitive LC-MS/MS method for the quantitative analysis of sulfonamides antibiotics in milk.

Beta-adrenergic receptor agonists (ß- agonists) are synthetic drugs utilized in the treatment of conditions such as asthma in humans, and are also used as a growth-promoting agent in food-producing animals. The use of ß- agonists in food-producing livestock has been either banned or regulated across many countries owing to human health concerns.

To aid in the monitoring and detection of ß- agonists in livestock, a highly sensitive and selective analytical method has been developed, and is presented in this study. This LC/MS/MS method details the analysis of 13 ß- agonists in pork samples, and utilizes isotopically-labeled internal standards to compensate for matrix effects present in complex food matrices.

In this work, we present a fast and sensitive LC/MS/MS method

Endocrine disrupting chemicals (EDCs) have been found to have harmful effects on the health of both humans and wildlife. Of these EDCs, endogenous estrogens, such as estriol, 17ß-estriadiol, and estrone are of particular interest due to their potency/physiological activity even at very low levels. These hormones are particularly challenging to monitor, as concentrations are typically expected to be in the low ng/mL (ppb) to low pg/mL (ppt) range.

To improve sensitivity, this work utilizes the addition of on-line solid phase extraction (SPE) coupled to an LC/MS/MS system for sample enrichment and quantitation. This approach allows for significant/efficient analyte concentration, obviating the need for elaborate and time-consuming sample preparation procedures. Due to enrichment, compared to other methods, large sample volumes (= ½ liter) are no longer needed to reach part per trillion levels for estrogen monitoring in river water.
