The core of PerkinElmer’s headspace is our patented pressure-balance technology that far surpasses valve and loop in performance when it comes to accuracy and repeatability. Pressure-balance provides rapid transfer of analytes to the GC without re-equilibration in a gas-sampling valve or syringe and minimizes loss of analytes. Injection amount is programmable by time or by volume without requiring any hardware change.

Butylated hydroxytoluene (BHT) is a common food additive used to protect foods from spoilage. Concern exists that long-term human consumption of BHT may have potential health risks. Analysis of BHT is needed for both food quality and safety reasons.
Trimethylamine (TMA) is a volatile organic compound known to be a major contributor to malodor pollution. Created in a gaseous form as a result of the manufacture, use and disposal of materials utilized in sewage treatment plants, the low odor threshold of TMA results in regular poor air quality complaints of residents living near treatment plants.
In this application note, a method for the analysis of TMA in the exhaust gas of a station pollution source is presented. Utilizing a PerkinElmer TurboMatrix™ HS-40 sampler and a Clarus® GC with nitrogen phosphorus detector (NPD), TMA is detected with MDLs well below the standards developed by US and Chinese regulatory bodies.
Although considered pharmacologically inert, pharmaceutical excipients have been shown to interact with active drug substances to affect the safety and efficacy of drug products.Therefore, there is an increasing awareness of the necessity to understanding interactions between excipients and the active pharmaceutical ingredient (API) in finished dosage forms.
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.
Thymopentin (TP5), a 5-amino-acid polypeptide, is a safe and effective immunostimulant utilized in the treatment of a variety of immune disorders. Several residual solvents are used in the manufacture of TP5, including the "universal solvent" N,N-dimethylformamide (DMF), known for its high solubility to a variety of organic compounds. United States Pharmacopoeia has established an 880 ppm maximum concentration level for DMF to reduce potentially negative influences on the human body. This application note describes a GC/FID method for the determination of DMF utilizing a PerkinElmer Clarus® 680 GC/FID with TurboMatrix™ HS-40. The method offers a simple, sensitive and efficient means of detecting DMF with good linearity, repeatability and low reporting limits.
Volatile organic compounds (VOCs) are a series of compounds with high vapor pressure and boiling points from 50 to 250 degrees centigrade. These characteristics lead to the tendency for large numbers of molecules to evaporate, or volatilize, from their solid state into the air. VOCs are present in the environment from a number of sources, both anthropogenic and naturally occurring. In soil, VOCs are mainly derived from discharged industrial and domestic sewage, oil spills, and chemical solvent leakages. Monitoring of VOC contamination in soils by both qualitative and quantitative analyses is important to ensure that the potential negative health impacts of VOC exposure are mitigated. In this study, thirty seven VOCs are investigated in a soil matrix, using a PerkinElmer Clarus® GC/FID and TurboMatrix™ HS-40. Detailed instrument method parameters are presented with precision, linearity and reporting limit results.
Epichlorohydrin, a raw material found in resins, can occur in drinking water at concentration which are hazardous to human health. The use of ephichlorohydrin is increasingly regulated. This article presents an analytical technique to determine the concentration of epichlorohydrin in the drinking water, in response to the requirements of the European Normative 98/83/EC, which recommends limiting the concentration to a maximum of 0.1 ug/L.
This application note demonstrates the use of a new sample-introduction technology incorporated in TurboMatrix HS-110 Trap for U.S. EPA Method 8260B for analysis, identification and quantification of volatile organic compounds (VOCs) that have boiling points below 200 °C.

Although considered pharmacologically inert, pharmaceutical excipients have been shown to interact with active drug substances to affect the safety and efficacy of drug products. One of the areas of major concern is the potential chemical interaction between impurities in the excipient and the drug molecules, leading to the formation of reaction products. Formaldehyde present in excipients has been implicated in the degradation of several drug products where it can form adducts with primary and/or secondary amine groups. It has also been reported that formaldehyde can induce cross-linking in gelatin capsules causing an adverse effect on in-vitro dissolution rates of drugs.
This application note presents a simple and effective method for the determination of formaldehyde in pharmaceutical excipients using SHS-GC/MS. The method is fast, reliable and can be used for the quantification of low-molecular-weight aldehydes in most excipients commonly used in pharmaceutical products.
This application note describes the automated HS-GC/NPD technique applied to the analysis of various type of rice samples.

To meet the growing demand for personal protective equipment following the beginning of the COVID-19 pandemic, face mask production from existing and new manufacturers increased drastically. Testing masks to confirm they do not contain chemical residues, such as volatile organic compounds (VOCs), that may off-gas during normal wear is an integral part of this quality control process. This application note presents a method based on ISO-18562 and ISO-10093 to detect and quantify VOCs in face masks. Utilizing a solvent-free headspace extraction and GC/MS analysis, this method is ideal for PPE producers seeking a quick and precise method to ensure safety and quality standards are met during the production process.
ASTM International publishes a number of different methods for the determination of volatile compounds in water-based coatings. Method D3960 is a gravimetric technique where a sample of known weight is baked under specific conditions; the % weight of volatile organic compounds (VOCs) is calculated from a series of measured masses. The method that was presented here will reliably analyze difficult compounds in a difficult matrix with great precision, linearity, and without carryover.
The development of methodology to measure VOCs at low levels using GC-MS coupled with Headspace Trap sample introduction is described here. The methodology is based on U.S. EPA Method 8260B.
