New Application Notes – PAHs, vapours from e-cigarette and tobacco, and essential oils

Tuesday, 21 June 2016 at 3:33:PM

Four new Application Notes have recently been published by Markes,​ covering applications of thermal desorption (TD) and time-of-flight mass​ spectrometry (TOF MS).

Application Note 115: Simple and reliable quantitation of ppt-level PAHs in air by TD–GC–MS.

This Application Note describes the performance of a sorbent tube and optimised analytical protocol dedicated to the detection of ppt-level polycyclic aromatic hydrocarbons (PAHs) in ambient air. Using active (pumped) sampling with analysis by TD–GC, this innovative approach completely avoids the labour-intensive solvent-extraction protocol employed in many standardised methods. The optimised analytical method also offers increased sensitivity due to increased extraction efficiency, absence of a dilution stage, and efficient transfer of compounds to the GC.

Application Note 118: Rapid profiling of VOCs and SVOCs in e-cigarette vapours for regulatory compliance and quality control.

This Application Note describes a simple, quick TD-based approach for the sampling and analysis of target compounds (such as nicotine, impurities and flavour compounds) in vapours from flavoured e-cigarettes. Used in conjunction with GC–MS analysis, the result is a versatile screening method for tackling the challenge of regulatory compliance and quality control in this rapidly expanding industry.

Application Note 537: Comprehensive insights into tobacco smoke constituents using TD–GC×GC–TOF MS with Tandem Ionisation.

This Application Note demonstrates the enhanced separation and unparalleled sensitivity that can be achieved in the characterisation of cigarette smoke, using TD and GC×GC with BenchTOF time-of-flight mass spectrometry, aided by Tandem Ionisation for simultaneous acquisition of hard and soft EI data.

Application Note 538: Detailed characterisation of essential oils by flow-modulated GC×GC–TOF MS with Tandem Ionisation.

In this Application Note, we describe the use of comprehensive two-dimensional gas chromatography (GC×GC) with BenchTOF time-of-flight mass spectrometry and Tandem Ionisation for characterisation and comparison of the composition of essential oils, aiding rigorous quality control.
