Volatile organic compounds (VOCs) have been recognized as a primary source of air pollution, and are known photochemical reaction precursors which facilitate the production of tropospheric, or ground-level, ozone. Ground-level ozone can have significant impacts on human health, and contributes to climate change throughout the world. VOC emissions from stationary sources, such as ducts, stacks and exhaust funnels in factories, refineries and mines, have been identified as significant contributors to air pollution and ground-level ozone formation. In this paper, a qualitative and quantitative method for the analysis of 24 polar and nonpolar VOCs was established using a PerkinElmer TurboMatrix^™ ATD and a PerkinElmer Clarus^® GC/MS with electron ionization (EI) source. The method is simple, sensitive and efficient to comply with regulatory requirements.

Solvent such as supercritical CO2, butane, propane, other hydrocarbons, water, or alcohol are used to extract out the cannabinoids and terpenes from the plant material. In some cases, the solvent and impurities from the solvent remain in the extracted material. This study will shows the analysis of residual solvents using pressure-balanced headspace (HS) sample introduction coupled with Gas Chromatography/Mass Spectrometry (GC/MS). Unambiguous separation of all compounds is obtained while maximizing sample throughput.

The European Union directives assist the member states to define the activities to be programmed and the objectives to be achieved.

This application shows this framework could be achieved with GC/MS analysis.

Hops are a critical ingredient in beer. Aroma characterization of hops is complex; there are many compounds in hops that contribute to flavor. This application note describes a system that is able to provide both an objective chemical analysis of hop aroma using gas chromatography/mass spectrometry and, at the same time, provide the means for the user to monitor the olfactory character of each component as it elutes from the chromatographic column. Such an approach allows the user to gain a fuller characterization of a particular hop sample.

Chlorophenols are by-products of the drinking water purification process and are also widely used as wood preservatives, herbicides and pesticides. In this study, the derivatization and extraction happened in the headspace vials during the vial thermostatting step. The derivatization reaction is affected by temperature and time, therefore the thermostat time and oven temperature of the headspace sampler were investigated for optimum derivitization/extraction conditions.

Polycyclic aromatic hydrocarbons (PAHs), a class of complex compounds containing two or more benzene rings, are widely found in the environment and food. PAHs are formed during the incomplete combustion of organic matter, such as wood utilized in cooking and food preparation. They have attracted wide attention due to studies which have shown the teratogenicity and carcinogenicity of PAH compounds. For humans, food intake is one of the main sources of PAH exposure, and can be the result of contamination from anthropogenic sources, food processing or cooking practices.

In this paper, a validated method employing accelerated solvent extraction (ASE) and gel permeation chromatography (GPC), followed by solid phase extraction (SPE) on silica and analytical determination by GC/MS was applied for the detection of PAHs in smoked meat. The results demonstrate that the method is suitable for the simultaneous determination of 24 PAHs in smoked meat with good efficiency, accuracy and reproducibility.

Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partially halogenated paraffin hydrocarbons. CFCs, in the form of polyether polyol mixtures, have been widely used as blowing agents in the manufacture of rigid polyurethane foams (PU) used as insulation products. Owing to the contribution to ozone depletion, the manufacturing and use of CFCs and HCFCs have been phased out under the Montreal Protocol (1987), however, recent studies have found that atmospheric levels of CFCs are significantly higher than expected, suggesting that production and use of CFCs are still on-going. In this study, trichlorofluoromethane (CFC-11), chlorodifuoromethane (HCFC-22) and dichlorofluoroethane (HCFC-141b) in a polyether polyol matrix are investigated using a PerkinElmer Clarus^® GC/MS with a TurboMatrix^™ HS-40. Instrument method parameters utilized in the study are presented herein, with detailed results demonstrating superior precision, linearity, sensitivity and recovery.

Semivolatile organic compounds are readily found in the environment, and pose a threat to human and animal health. As such, most nations have placed limits on the amount and types of SVOCs that can be released into the environment, owing to their difficult degradation and numerous sources. One of the most widely referenced methods for the analysis of SVOCs in environmental matrices is US EPA Method 8270D.

In this application note, results are presented from an analysis utilizing Method 8270D with a fast and simple single-step liquid-liquid extraction technique, followed by a large-volume direct injection of the extract into a PerkinElmer Clarus^® SQ8 GC/MS with a D-Swafer^™ system for concentration, separation and quantification.

Food packaging plays a key role in food safety and public health therefore it must be carefully controlled. The Commission Regulation (EC No. 2023/2006) has made it mandatory to adopt a system of Good Manufacturing Practice (GMP) to ensure a consistently high quality both in production and control process which includes the prohibition of any contacts between printed side of the package and the food inside.

Volatile organic compounds (VOCs) are a series of compounds with boiling points from 50 to 250 degrees centigrade and are widely used as industrial chemicals/ solvents. Low concentrations of VOCs can have a significant impact on human health, as many are regarded as highly toxic, refractory and carcinogenic. The detection and determination of VOCs in the environment is of the upmost importance for both human and environmental health.

Customer complaints of odors within a new car are rising with the increasing number of new car buyers. Although odors can be subjective, it is now well known that the new car smell is the result of chemicals emitted from the in-vehicle interior components such as the dashboard, interior panels, seat coverings, flooring materials, and so on. This application note describes a method for the automotive industry that provides a qualitative analysis and the olfactory character of each component using the TD-GC/MS-Olfactory Port.

The EU Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulation was adopted in 2006 with the aim of protecting human and environmental health, along with the competitiveness of the chemical industry within the European Economic Area. The regulation places responsibility for chemical product evaluation and compliance on manufactures and importers, as opposed to the government.

In this application note, a method utilizing a PerkinElmer Clarus^® GC/MS for the analysis of 4,4’-Methylenebis(2,6-di-tert-butylphenol), also known as Ethyl 702, is described. The method fulfills the REACH requirement by using the ammonia adduct ion to confirm the compound molecular weight. Improved analytical results were obtained using a mass flow control (MFC) mechanism for the regulation of the CI reagent gas flow.

BTEX is a grouping of structurally similar volatile organic compounds including benzene, toluene, ethyl benzene and the three xylene isomers. These compounds are known pollutants and are typically found near petroleum production and storage sites. BTEX are regulated toxic compounds while benzene is also an EPA target carcinogen. The investigation of these compounds, especially in drinking water at low levels, is critical to protect public health. This application note focuses on exceeding the current EPA detection limit requirement for BTEX while meeting and/or exceeding all other criteria in EPA method 524.2 for these analytes.
