Application Note 514: Analysis of polycyclic aromatic hydrocarbons from vehicle exhaust using TD–GC–TOF MS and TargetView software
This Application Note describes the use of BenchTOF and TargetView to confidently identify polycyclic aromatic hydrocarbons (PAHs) in diesel exhaust particulate. The sensitivity and ‘classical’ spectra produced by BenchTOF allow accurate identification of PAHs with near-identical fragmentation patterns, while TargetView enables GC profiles of trace-level analytes to be visualised even when hidden under much more abundant components.
Application Note 518: High-performance screening of pollutants in water using GC×GC–TOF MS
This Application Note demonstrates how the latest sampling techniques, combined with GC×GC separation and BenchTOF detection, offer considerable advantages for the identification of pollutants in river water. The quality of the analysis is illustrated by reference to the detection of PAHs, PCBs and pesticides, while the ability of the method to detect ‘unknowns’ with little additional effort is demonstrated by the identification of polycyclic musks.
Application Note 521: The advantages of a TD–GC–TOF MS approach for detecting trace-level odorants in polluted air
This Application Note shows how the inherent sensitivity of the BenchTOF allows automated detection of trace-level odorants in air taken from the outflow of a biological waste processing plant. At the same time, the value of TargetView is demonstrated by applying it to a targeted search for odorous sulfur compounds.
Application Note 525: Rapid analysis of environmental contaminants by fast GC–TOF MS with Select-eV variable-energy electron ionisation
This Application Note shows that BenchTOF time-of-flight mass spectrometers provide a robust, high-performance and highthroughput solution for screening multiple trace-level environmental contaminants. Revolutionary variable-energy electron ionisation is also shown to aid compound identification and enhance the selectivity and sensitivity of analyses by generating secondary (qualifying) mass spectra with reduced fragmentation and a stronger molecular ion signal.
Application Note 529: High-throughput, cost-effective analysis of environmental air contaminants in accordance with US EPA Method TO-15 using GC–TOF MS
This Application Note shows that the cost-effective combination of cryogen-free automation and rapid GC–TOF MS analysis delivers robust, high-throughput determination of priority hazardous air pollutants in accordance with US EPA Method TO-15. As well as allowing up to $200,000 additional revenue to be generated per year per system, the enhanced analytical performance of the new system opens up fresh application opportunities.
Application Note 531: Extended detection limits for GC–TOF MS of organotins using Select-eV variable-energy electron ionisation
This Application Note demonstrates how the enhanced sensitivity and selectivity of the BenchTOF time-of-flight mass spectrometer with Select-eV variable-energy electron ionisation can provide ultra-trace-level quantitation of organotins in complex environmental extracts. We focus on how Select-eV soft ionisation offers particular advantages in the analysis of organotin species, which undergo extensive fragmentation at conventional 70 eV ionisation energies, by producing simplified spectra with enhanced diagnostic ions.
Application Note 534: Fast and confident quantitation of environmental contaminants using GC–TOF MS
This Application Note demonstrates how the excellent sensitivity, stability and high-quality spectra produced by BenchTOF mass spectrometers, with data analysis by TOF-DS software, can provide a rapid and robust solution for the quantitative analysis of environmental contaminants.
