LCMS-8060 Application - Fully automated derivatization - quantification of Glyphosate and AMPA in beer using a standard UHPLC-MS/MS system
Glyphosate is currently one of the most common pesticides used worldwide. In spite of its approval by regulatory bodies all over the world, the concern about its harm to humans and the environment persists. Therefore, the strict control of Glyphosate and its metabolite Aminomethylphosphonic acid (AMPA) in food and environment is mandatory. The chromatography of glyphosate is challenging due to its high polarity. In order to overcome this, there exists a well-established method including a derivatization step with 9-fluorenylmethyl chloroformate (FMOC) followed by LCMS analysis. Here we report a fully automated derivatization followed by LC-MS/MS analysis of beer samples. The instrumental set-up does not require any additional hardware for sample pretreatment but uses the built-in pretreatment function of the autosampler.

LCMS-8050 Application -Vitamins in Milk Infant formula
Milk infant formulas are generally enriched with vitamins and complements which are essential for normal health and growth. The manufacturers must insure that their content is controlled properly. Also they must certify the absence of certain contaminants. Traditional methods to measure complements and contaminants in this matrices are based on HPLC thanks to the possibility of rapid separation and quantification. Mass spectrometry detection is the gold standard due to its specificity, precision and sensitivity. However, because of the high variability of structures and chemical properties of this analytes, several methods are needed for both their extraction and their separation by chromatography. We here report a unified solution for the quantification of all of this compounds in milk infant formulas.

LCMS-8060 Application - Application of SFC-MS/MS for the quantification of highly polar pesticides in a range of food samples
The analysis of highly polar pesticides by LC-MS/MS is typically achieved by several specific methods with limited chemical space. The EU Reference Laboratories for Residues of Pesticides Single Residue Methods (EURL-SRM) have published QuPPe (Quick Polar Pesticides) methods for the simultaneous analysis of a number of highly polar pesticides which cannot be easily analysed using routine QuEChERS based extraction methods and multi-residue methods (M. Anastassiades et al; QuPPe of EURL-SRM (Version 9.1; 2016). To meet the needs of analysing highly polar pesticides by LC-MS/MS several chromatographic conditions have been used including hydrophilic interaction liquid chromatography (HILIC), zwitterionic-type mixed-mode, normal-phase columns operated in HILIC-mode (bare silica and silica-based chemically bonded columns (cyano and amino)), reversed-phase C18 and carbon based phases. In this work SFC-MS/MS was applied to the analysis of a panel of highly polar pesticides extracted from several food matrices by QuPPe.

LCMS-8060 Application - Developing a Chiral Amino Acid Analysis Method That Uses Column Switching (Japan)
Analysis of D-amino acids is susceptible to interference by a wide variety of peptides and amino compounds, and therefore requires high sensitivity and highly selective analysis methods for accurate measurement. Furthermore, conventional optical separation analysis of amino acids necessitated derivatization and long separation times of the amino acids. This article introduces a rapid analysis method that employs chiral columns to achieve high separation and high sensitivity and that dispenses with derivatization. This system uses two types of chiral columns alternately with high-pressure column switching valves (FCV) and allows fully automatic analysis of a wide range of D- and L-amino acids.

Analysis of Minerals and Harmful Elements in Formula Milk Powder Using ICPMS-2030
Formula milk powder is formulated to contain a good balance of minerals necessary for infant growth. Japan's Health Promotion Law includes stipulations on the essential mineral content, including calcium (Ca), iron (Fe), and copper (Cu), of food for special dietary use (e.g., formulated milk powder for infants) and requires the labeling of their content. 1) Harmful elements like lead (Pb) have a negative effect on infant development, and require strict safety controls from raw materials to the finished product. We describe using Shimadzu's ICPMS-2030 inductively coupled plasma mass spectrometer to perform a simultaneous analysis of elements present in formula milk powder (National Metrology Institute of Japan certified reference material [NMIJ CRM]). In addition to being highly sensitive, the ICPMS-2030 uses a helium gas collision system that greatly reduces the spectral interference caused by argon and chlorine.

Improved sensitivity for characterization of sulfonamides and trimethoprim in honey using QuEChERS extracts with LC-MS/MS.
Improved sensitivity for characterization of sulfonamides and trimethoprim in honey using QuEChERS extracts with LC-MS/MS.A natural food as honey is subject of diverse restrictions for contaminants presence as the case of antibiotics including sulfonamides. It is a worldwide practice by Beekeepers to use antibiotics as therapeutic agents to treat bee bacterial brood diseases, however the use of sulfonamides (SA) and trimethoprim (TMP) in beekeeping practice is prohibited in EU. There are no a worldwide MRL’s for sulfonamides in honey in the EU, but a minimum required performance level (MRPL) was set for analytical methods at a level of 10 μg/kg of sulfonamides, encouraging the development of reliable laboratory methods for detection in diverse foods included honey. SAs and TMP posing threats to public health causing allergic reactions and increasing microorganism’s drug resistance. Considering MRLs and MRPL of SAs and TMP in food products from animals tend to be continually reduced to preserve human health safety, HPLC-MS/MS is an effective strategy to characterize and accurately measure those antibiotics. The present method is selective, fast, and very sensitive for 20 sulfonamides and trimethoprim.

Nexera Application - Reducing Organic Acid Analysis Times Using SIL-30AC Autosampler
Organic acid counter-ions found in food and drugs are considered important components as they decide the flavor of food and properties of drugs. Food in particular contains a large number of substances analyzable with LC-MS, though LC-MS is unable to detect formic acid and acetic acid in foods due to its use of formic acid and acetic acid in the mobile phase. Combining ion exclusion mode HPLC with post-column reaction detection (post-column pH-buffered electrical conductivity detection) is an approach that does not use formic acid or acetic acid in the mobile phase, and therefore allows the selective and highly sensitive detection of formic acid-containing and acetic acid containing organic acids. However, this approach uses 2 columns to achieve high resolution separation, which increases time to detection. Another problem with this technique is the large number of constituents targeted by food analysis, and the time required to analyze standard reference solutions for calibration curve creation. This article describes using the overlapping function of SIL-30AC to shorten the time required for continuous analysis of organic acids.

LCMS-8060 Application - High Sensitivity Analysis of Pesticides in Dried Hops Cones and Hops Pellets
Hops (Humulus lupulus) are an essential ingredient in brewing beer but agricultural production of this plant is threatened by insects and other dangers. Pesticides and other chemicals may be used to protect hops and increase yield, but certain chemical residues may be harmful to consumers. Chemical residues may also have unintended negative effects on non-target insects such as honeybees. Sensitive and selective detection of chemical residues in hops is necessary to ensure protection of consumers and the environment. Methods using LC-MS provide efficient and effective detection of chemical residues in a complex sample matrix such as hops. We have developed an LC-MS method for detection of over 150 analytes in hops and carried out a market survey of over 50 different hops pellets samples.

AA Application - Analysis of the Lead Content of a Coffee Beverage by Graphite Furnace Atomic Absorption Spectrometry
Graphite furnace atomic absorption spectrometry (GFAAS, electrically heated atomic absorption, flameless atomic absorption) is capable of highly sensitive analysis of many different elements. GFAAS can also remove organic materials in particular from samples during analysis as it performs atomization via drying and ashing steps using a temperature program. GFAAS can consequently be used to analyze beverages, watersoluble foods, biological samples, organic solvents, and water-soluble organic compounds without needing to perform degradation pretreatments. However, the properties of these untreated samples differ from those of aqueous solutions subjected to degradation pretreatment, and corresponding care is needed during sample injection and drying. This Application News describes the direct analysis of lead in a commercially available coffee beverage without pretreatment using GFAAS, and introduce the GFA-TV graphite furnace atomizer camera‒a convenient optional product that allows observation inside the furnace during sample injection and drying.
