New 8 Gas Chromatography/Mass Spectrometer (GC/MS) PerkinElmer announce the launch of its Clarus®
SQ 8 Gas Chromatography/ Mass Spectrometer (GC/MS), setting
a new industry benchmark for sensitivity and stability. The Clarus SQ 8 GC/MS provides extreme sensitivity to analyse samples accurately, with an 800:1 signal to noise specification. This capability gives environmental and food testing laboratories the ability to detect lower levels of contaminants and impurities. The Clarus SQ 8 GC/MS delivers superior throughput and productivity by minimising requirements for calibration of instruments and reducing the need for sample preparation and concentration, dramatically improving workflow. PerkinElmer’s Clarus SQ 8 GC/MS provides accurate results, which allows environmental and food testing laboratories to comply with new and evolving regulatory requirements that drive compliance in environmental and food applications. “The quality and safety of food products are major issues worldwide, and accurate analysis of pesticide residues and other contaminants is imperative to monitor the interplay between human and environmental health,” said Dusty Tenney, president, Analytical Sciences and Laboratory Services, PerkinElmer. “We work hand-in-hand with the world’s leading environmental and food testing labs, and our introduction of the new Clarus SQ 8 GC/MS emphasises our commitment to giving customers the right tools to solve the growing challenges of these markets.” The Clarus SQ 8 GC/MS is the easiest GC/MS to maintain based upon an innovative SMARTsource™ design, delivering increased productivity and consistent, reliable results. These new features are further complemented by the patented GC oven, which has the fastest heat-up and cool-down times for shorter injection-to-injection and analytical cycle times. The Clarus SQ 8 GC/MS also significantly reduces background noise in turn delivering higher levels of confidence in the testing of foods for human consumption.

Dionex announces a rapid separation liquid chromatography (RSLC) tandem massspectrometric (MS/MS) method for quantitative analysis of ethanolamines in environmental water samples. Application Note 271:Quantitative Analysis of Nitrogen Mustard Hydrolysis Products as Ethanolamines demonstrates use of the Dionex Acclaim®
Trinity™ P1 Mixed-Mode column, featuring reversed-phase, anion-exchange, and cation-
exchange retention mechanisms, to provide retention and resolution for five target analytes within 5 minutes. Over half a million tons of ethanolamines are produced annually and used as emulsifying agents, detergents and cosmetics, and also in the pesticide manufacturing process. Inefficient removal and or inappropriate disposal of ethanolamines may cause adverse effects to the environment. By using a mixed- mode analytical column and selective multiple reaction monitoring (MRM) MS/MS detection, this method shows significant improvements over previously reported methods with minimum sample preparation, total chromatographic resolution, capability of sub-ppb level quantification, and high throughput. Application of this method to the analysis of surface waters is demonstrated and shows no quantifiable amounts above the lowest reporting limits (LRL). Matrix effects and recovery are evaluated using two surface water matrices and the results.

loop technique (MiPT) it is possible to inject different sample volumes with just one fixed injection loop, which facilitates a broad range of sample concentrations to be analysed without any changes to the system and also to conveniently perform a multi-point calibration with just one multi ion standard. Due to the logical features of the MagIC Net controlling software, the partial loop technique can even be used as an alternative to intelligent dilution and could also be combined with other techniques such as ultrafiltration. MiPT is a novel and unique setup that can be added to any 850 Professional IC, 881 Compact IC pro or 882 Compact IC plus in combination with the intelligent 800 Dosino in combination with the 858 Professional Sample Processor with rinsing station. The Dosino dosing unit allows sample volumes between 2-200µl to be injected quickly and precisely into the ion chromatography instrument and this principal can be applied to the calibration standards so that it is possible to prepare a mg l-1 to µg l-1 calibration with no handling of individual standards which can be both time consuming and introduce possible errors.
