Automotive Studies using Thermal Desorption

4 Jan 2017

This is a comprehensive guide to using thermal desorption in the vehicle-manufacturing industry. The guide describes how thermal desorption can be applied to various applications in the industry including vehicle interior air quality monitoring, analysis of polycyclic aromatics hydrocarbons (PAHs) and detecting volatile carbonyl compounds, and directs you towards relevant application notes which describe the methods in detail. The guide also describes relevant analytical and sampling techniques and outlines the advantages of using thermal desorption in automotive studies.

Micro-Chamber/Thermal Extractor
Markes International Ltd
Fast sampling of emissions from products and materials. The Micro-Chamber/Thermal Extractor™ (µ-CTE™) is a versatile and compact unit with up to six small cylindrical chambers that enables the sampling of chemicals released from products or materials. Released volatile and semi-volatile organic compounds (VOCs and SVOCs) are collected onto sorbent tubes for analysis by TD–GC–MS. The capability of the Micro-Chamber/Thermal Extractor has been further extended by the release of the Humidifier Accessory, which supplies the Micro-Chamber/Thermal Extractor with air or gas at up to 50% relative humidity. Features: The four-chamber model has a chamber volume of 114 mL and a maximum temperature of 250°C The six-chamber model has a chamber volume of 44 mL and a maximum temperature of 120°C Volatiles are collected on sorbent tubes for analysis by TD–GC–MS; also compatible with DNPH cartridges for formaldehyde monitoring No sample preparation needed – simply place the material in the chamber A constant flow of heated air or gas ensures rapid production of a representative VOC/SVOC profile Results can be correlated with longer-term reference methods Construction from inert-coated stainless steel – compatibility with reactive or thermally labile chemicals Accessories allow surface-only sampling or permeation testing An optional humidifier accessory (available for both models of microchamber) supplies air/gas at up to 50% relative humidity to allow closer simulation of conditions used in reference tests and to enhance the recovery of some less-volatile polar compounds Benefits: Save time and money by minimising the need for third-party reference tests Convienient and fast – test multiple samples in minutes, not days, for efficient quality control Confidence in results – Data from the Micro-Chamber/Thermal Extractor has been shown to correlate with longer-term reference-test results Avoid tedious and time-consuming sample preparation – simply place your sample in the microchamber Complies with international standard methods ISO 12219-3 (interior air of road vehicles) and ASTM D7706 (rapid screening of VOC emissions from products) Peace-of-mind – you are buying a quality product from the recognised leader in thermal desorption instrumentation Applications: RMicro-Chamber/Thermal Extractor analysing Rapid emissions screening of materials used indoors and in vehicles, especially to aid compliance with regulations and safety labels Product R&D and formulation of lower-emitting products Testing of raw materials and production-line quality control Comparison with competitors’ products Testing permeation of vapours through materials Aroma profiling of foods or fragranced materials

MTS-32
Markes International Ltd
Multi-tube sequential sampler. The MTS-32™ is a compact, portable sampler for the unattended sequential sampling of air onto a series of sorbent tubes. Constant-flow pump technology ensures that the same volume of air is collected onto each tube.The MTS-32 is ideal for analysts needing monitor the concentrations of organic vapours in air as they fluctuate over extended time periods.Features: Sequentially samples on up to 32 × 3½-inch tubes. Constant-flow pump ensures consistent sample volumes regardless of variations in tube impedance. Diffusion-locking technology (Markes’ SafeLok™ tubes or DiffLok™ caps) prevent sample losses and ingress of contaminants. Integral fan continually refreshes the air inside the case, ensuring that the air sampled accurately reflects the immediate environment. Powered by mains electricity or a battery (will run for over 40 hours on battery). Protective gauze across the fan inlet prevents particulates or wildlife from entering. Constructed of low-outgassing components. Field-portable – the MTS-32 can be used virtually anywhere. Applications: Monitoring diurnal fluctuations of pollutants in ambient air. Continuous monitoring of emission events in industrial locations.

Easy-VOC
Markes International Ltd
Grab-sampler for air sampling. Easy-VOC is a hand-held device that facilitates the rapid ‘grab’ sample collection of small volumes (<500 mL) of air directly onto sorbent tubes without the need for calibrated pumps.Sorbent tubes attach to the end of the Easy-VOC and air/gas is drawn directly onto the tube. Easy-VOC regulates the flow rate independent of the force used to pull the air through.Grab sampling involves collecting volumes of air or gas over a very short period of time. Sampling onto sorbent tubes in this manner offers many advantages over other methods, which can be cumbersome, expensive and inaccurate.Features & Benefits: Easy grab sampling onto sorbent tubes No pump to calibrate 50–500 mL volumes More versatile alternative to canister sampling - compatible with n-C3 to n-C32 Fits ¼-inch and 6 mm o.d. sorbent tubes

ACTI-VOC
Markes International Ltd
ACTI-VOC™ is a robust low-flow pump for sampling vapour-phase organic compounds (VOCs) onto sorbent tubes for subsequent analysis by thermal desorption (TD). Being lightweight, easy-to-use and intrinsically safe, ACTI-VOC is ideal for personal monitoring and a wide range of other air and gas sampling applications. Optimised for thermal desorption tubes Unlike other personal monitoring pumps on the market, ACTI-VOC is optimised for sampling onto thermal desorption tubes, and automatically compensates for different impedances, ensuring constant flow rates whatever the sorbent packing. Product highlights • Optimised for sampling onto thermal desorption tubes • Compatible with any thermal desorption tube (up to a max. flow of 350 mL/min) • Constant-flow sampling from 20–200 mL/min • Constant-pressure sampling from 1–350 mL/min • Simple screw-operated flow adjustment makes ACTI-VOC easy to calibrate • Intrinsically safe (ATEX-approved) • Long battery life ensures stable performance for over 8 hours • Pocket-sized, lightweight and easy to use • Supplied in a convenient carry-case with charger and accessories
