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.

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.
Pyrethroids are a type of synthetic insecticides that work by attacking arthropod insects’ nervous system, with a knockdown and cidal effect that is up to 100 times higher than that of older generation insecticides, such as organochlorine (OC), organophosphorous (OP) and carbamate pesticides. Pyrethroid pesticides are used widely in agriculture, public health and grain storage, and have become one of the most widely used pesticides. Recent studies indicate that pyrethroid pesticides can bioaccumulate in some species, and that prolonged exposure may result in chronic disease, even with relatively low-dose exposure. As such, a number of countries have developed regulatory guidelines associated with safe levels of pyrethroid pesticide residues in the environment.
In this study, a Soxhlet extraction technique is used to extract target 10 pyrethroid pesticides from soil samples, with subsequent analysis using a PerkinElmer Clarus® SQ 8 GC/MS system.
Chlorophenols are by-products of the drinking water purification process and are also widely used as wood preservatives, herbicides and pesticides.

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.
Pesticides are a broad class of compounds used to kill a wide range of unwanted pests encountered in agricultural operations, including insects, rodents, fungi and unwanted plants. Organophosphorus pesticides (OP), generally thiophosphate or phosphate ester compounds, work by inhibiting the enzyme acetylcholinesterase, which is essential to both insect and human nervous system function. As such, OP pesticides pose a health risk not only to the pests it targets, but also to humans coming into contact with residues.
In this study, a Soxhlet extraction technique is used to extract target pesticides from soil samples. Following extraction, the extracts are analyzed by liquid injection into a PerkinElmer Clarus® SQ8 GC/MS system. The results demonstrate that the method is accurate and reliable in the analysis of OP pesticides in soil samples.
Bromoethane (EtBr) occurs both naturally and anthropogenically, and is widely used as a broad-spectrum pesticide in grain storage fumigation to prevent fungi and weed production, or control insect and rodent populations in storage facilities. Owing to potential health risks when inhaled or consumed, EtBr has been banned in many countries, in addition to being classified as a carcinogen and reproductive toxin by the State of California. Although many studies have focused on EtBr in ambient air, this work describes a method for the analysis of EtBr in drinking water, utilizing a headspace sampling technique, followed by analysis by GC/MS utilizing a Clarus SQ 8 system.
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.
Plastic bags are widely used in food packaging due to cost and flexibility, for example breakfast items such as hot steamed buns, oil cake and soybean milk are typically packaged in plastic. Leftovers, supermarket cooked food and even beer, are also packaged with plastic bags. Plastic packaging is very convenient but plasticizers and other additives dissolve and migrate into food during processing, heating and packaging, which can result in food contamination and permanent damage to human health and the environment.
This application note demonstrates a method for the determination of 16 phthalates (PAEs) and 16 polycyclic aromatic hydrocarbons (PAHs) leaching from plastic bags using the PerkinElmer Clarus® SQ 8 GC/MS with electron ionization (EI) source. The method is based on the Chinese National Standards GB 31604.1-2015, GB 31604.30-2016 and GB 5009.265-2016. 1-3 Toluene is used as a solvent to extract the target compounds from the food simulants.
