The Indoor Air Quality and Material Emission Testing Lab (IAQ amd MET Lab) offers a range of general and specialised research and analytical services to qualify and measure volatile organic compound (VOC) emissions from different products and materials as well as measuring VOCs within different indoor environments.
Our team consists of international leaders in the assessment of the indoor built environment, with a focus on indoor air quality, building and product emissions, and health and productivity effects.
Our services can measure, assess, and evaluate VOC emitted from building materials with the focus on reducing exposure to VOCs within indoor environments. We also provide researchers and clients our expertise and skills in research and analytical instrumentation to achieve their outcomes.
Available Equipment
Headspace Gas Chromatography / Mass Spectrometer (GC/MS)
Gas Chromatography / Mass Spectrometer (GC/MS) is an analytical technique that combines the separation properties of gas chromatography with the detection feature of mass spectrometry to measure and identify different compounds within a sample. Quantification of known compounds is then performed using a calibration curve using various concentrations of standards samples.
Headspace GC/MS is used to measure, quantify, and compare VOC emissions from different materials and products. Headspace GC/MS analysis is performed using a Shimadzu GC/MS-QP2010 Plus instrument with an automated Shimadzu AOC-5000 sample injection system. The volatile components are identified based on the mass spectral library of the National Institute of Standards and Technology (NIST). Potentially hazardous VOCs are identified based on classifications of Safe Work Australia (2021) and the World Health Organization (2021).
GC/MS equipped with Automated TurboMatrix Thermal Desorbers
Indoor air quality analysis is performed using GC/MS equipped with Automated TurboMatrix Thermal Desorbers. Indoor air samples are collected in multi-adsorbent tubes based on the USEPA compendium methods using an SKC AirzChek Touch sampling pump. Samples are analysed according to the US EPA method TO–17 using a GC/MS equipped with a PerkinElmer TurboMatrix 350 Automated Thermal Desorber (ATD). The volatile components of products are identified based the NIST library.
Handheld devices
[left] Q-Trak™ IAQ Monitor, model 7575 features a menu-driven user interface for easy operation and provides quick, accurate information to measure and assess key IAQ parameters.
[right] DustTrak™ DRX Aerosol Monitor simultaneously measures both mass and size fraction. This device is a multi-channel, battery-operated, data-logging, light-scattering laser photometer that gives us real-time aerosol mass readings and collects a gravimetric sample.
