Using Markes’ Emissions Screening Technology to Simplify Compliance with Construction Product Regulations

7 Aug 2014

This Application Note describes recent regulatory changes affecting the manufacturing industry, and how Markes’ micro-chamber technology allows manufacturers to minimize the burden and maximize opportunities for product development.

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

Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples. Find the best atomic absorption, photoelectron and optical emission spectrometers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.ScreeningUsing robotics, data processing and control software, liquid handling devices and sensitive detectors, screening allows a researcher to quickly conduct millions of chemical, genetic or pharmacological tests.Volatile Organic Compounds (VOCs)Volatile organic compounds (VOCs) are chemicals that have a low boiling point. Some VOCs are harmful to human health, whereas others can be used to determine the shelf-life of foods samples. Semi Volatile Organic CompoundsSemi volatiles organic compounds (SVOCs) are a groups of compounds that have a low boiling point and evaporate above room temperature. SVOCs include phenols and polynuclear aromatic hydrocarbons (PAH).VolatilesVolatiles are a group of compounds that have a low boiling point and evaporate at room temperature. Volatiles, such as volatile organic compounds (VOCs), can be used to determine shelf-life of food samples. GC-MS is typically used to analyze volatiles.
