The described method consists of a simple methanol dilution, followed by a direct injection to LC-MS/MS. The Triple Quadrupole MS, LCMS-8060, was used in this study to effectively separate and quantify 49 PFAS, with all compounds eluting within 13 minutes. ...
A total of 27 PFAS were extracted, separated and detected with triple quadrupole mass spectrometers, LCMS-8045 and LCMS-8050. Recoveries of 86-106% (LCMS-8050) and 77-104% (LCMS-8045) were well within the limits outlined in EPA 537. ...
There has been an increasing awareness of the presence of polyfluorinated alkyl substances (PFAS) in water. A simple and robust method with quick turn-around time to determine these compounds is essential to providing accurate responses in a timely manner. In the method presented here, direct injection without solid-phase extraction (SPE) allows us to maximize throughput and to minimize ...

Environmental analysts are often tasked with the evaluation of illicit and prescription drugs in wastewater samples in an attempt to better understand the epidemiology of a populated area. Due to the challenging consistency of this matrix, clean-up is often vital in order to achieve accurate detection. In a recent paper authored by Richard Bade et al., published in Analytical and Bioanalytical ...
We have Genius 3020, 1051, 1050 and NM32LA nitrogen gas generators supplying our LCMS-IT-TOF and triple-quadrupole mass spectrometer LCMS-8060, LCMS-8050, LCMS-8045 and LCMS-8040. 3. ...
We evaluated the instrumental portion of the methods using the Shimadzu LCMS-8060 triple quadrupole mass spectrometer. Calibration ranges and estimated detection limits were well within method specified ...
Liquid Chromatography coupled to a triple-quadrupole Mass Spectrometer (LCMS/MS) was used to determine pesticide residues from the botanical samples. ...
Abstract The determination of Melamine and Cyanuric Acid go hand in hand with one another. Melamine is an industrial chemical used in the manufacturing of amino resins, plastics, and flame retardants. Cyanuric Acid is produced by the hydrolysis of raw or waste Melamine, followed by crystallization. Melamine is used as a profitable adulterant in milk based products to increase the protein content ...
The drug development process requires pharmacokinetic (PK) analysis to be performed as part of safety and efficacy studies in both preclinical species and human subjects. For high-sensitivity bioanalysis, liquid chromatography (LC) coupled to a triple quadrupole mass spectrometer (LC-MS/MS) is considered the gold standard for quantification. However, for some low-exposure applications, ...
Pyrethroid pesticides are used widely around the world as agricultural and household insecticides. Synthetic pyrethroids are slightly soluble in water and easily adsorbed in soil. In recent years, pyrethroid residues have been confirmed in soil and sediment in both agricultural and urban areas. Pyrethroids, while posing little danger to humans, exhibit a high toxicity to aquatic organisms and ...
Abstract The Sudan dyes Sudan I, Sudan II, Sudan III and Sudan IV all belong to the compound group named Azo-dyes. The International Agency for Research on Cancer has listed these dyes to be considered a possible carcinogen. The EU has released a commission decision 2005/402/EC to ban such Sudan dyes as food additives. The goal of this project is to evaluate the performance and versatility of an ...
Abstract Imidazolinone herbicides are a family of five compounds including: Imazapyr, Imazapic, Imazethapyr, Imazamox, and Imazaquin. These herbicides are used to control a wide range of broadleaf weeds, by inhibiting the Acetohydroxy Acid Synthesis (AHAS), which is the first common enzyme in the biosynthesis of branched chain amino acids. In this study, the performance and versatility of the ...
In this analysis, microcystins-RR, YR, and LR were measured using a Nexera UHPLC with a LCMS-8050 triple quadrupole MS detector with ESI ionization in accordance with EPA Method 544. ...
We developed an ultra fast UHPLC-MS-MS method for analysis of carbendazim in orange juice using a new high speed autosampler, the Nexera SIL-30ACMP in tandem with a newly developed high sensitivity triple quadrupole mass spectrometer, the ...
This Application News introduces an example of analysis of the 3 haloacetic acids using the LCMS-8030 triple quadrupole mass spectrometer and is in accordance with this legislative ...
Pesticides are widely used in agricultural products to protect crops from insect infestation during cultivation and product transport. With the heightened concern for food safety, “Positive List System was introduced in Japan on May 29, 2006. These limits ban the sale of food containing pesticides that exceed specified concentrations to ensure the safety of food circulating in the market. ...
Organofluorine compounds such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) are highly stable chemical compounds which are widely used as water repellents, oil repellents and coating agents. These compounds do not decompose easily in the natural world due to their stability. Reports of their detection in rivers, streams, tap water, food, as well as in the atmosphere ...
