Although it was built for portability and speed, the low thermal mass (LTM) capillary GC provides equivalent chromatographic resolution and performance to a benchtop system. The miniature size is achieved by replacing a conventional convectively-heated column oven with a low thermal mass (LTM) column bundle with direct-contact electrical resistive heating. LTM GC uses a small diameter, metal capillary GC column, which is bundled with resistive heating and temperature-sensing wires that are braided Superior technology ? Small diameter LTM capillary GC for high speed, high resolution separation of chemical analytes ? Rapid temperature programming delivers analysis times of under three min. ? Sensitive and selective mass-based detection of a wide range of chemicals ? Easy to operate with a color touch-screen display and simple navigation buttons Figure 1. The Torion T-9 Low Thermal Mass Capillary GC is fast and operates reliably. Injection Port with Removable Liner LTM Capillary Column Bundle Cooling Fan Electronic Pressure Control GC Electronic Board together with insulator strands. This design provides for greater heating and cooling speeds and very low power consumption
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.
This study describes the injection, separation, and identification of 16 drugs compunds in less than 10 minutes using portable gas chromatograph-toroidal ion trap mass spectrometry (PerkinElmer, Torion T-9 Portable GC/MS) combined with a coiled-wire-filament (CWF) sampling injector to provide an effective tool for onsite analysis of illicit drugs substances.
This method outlines the analysis of volatile organic compounds in a variety of solid waste matrices including various air sampling trapping media, ground and surface water, soils, and sediments among others. The method requires not only demonstration of laboratory sample preparation and handling competence but instrument performance as well. The study presented here demonstrates the PerkinElmer? Clarus? SQ 8 GC/MS with purge and trap sample introduction both meets and exceeds the performance criteria set out in method 8260C and describes the analytical results and instrumental methodology.
In recent years there has been an increase in fatalities related to the use and consumption of opioids, a class of synthetically manufactured pain-relieving drugs similar to naturally derived opiates like morphine, opium, codeine, and heroin. This application demonstrates the use of the novel Custodion? Coiled Microextraction (CME) syringes and the Torion T-9 Portable GC/MS as a fast and easy to use screening tool for drugs of abuse and new psychoactive substances (NPS) in the field.
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.
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.
This study will demonstrate how the GC instrumental parameters are optimized so that VOCs, in addition to semi-volatile organic compounds (SVOCs), can be analyzed on the same instrumentation enabling enhanced throughput and laboratory efficiency. It will also discuss the number of samples required by each refinery depending on its size, in addition to the distribution of sampling sites around the refinery.
This study describes the recovery of compounds above the boiling point of naphthalene achieved by optimizing the thermal desorption chemistry for the determination of volatile organic compounds ranging from C3 to C26 in soil gas samples using Method TO-17. Figures of merit such as breakthrough, precision, linearity, and detection capability are presented, in addition to an evaluation of its real-world capability at sites with moderate diesel and semivolatile polynuclear aromatic hydrocarbon (up to pyrene) contamination, in the presence of high humidity. This research has provided a means to determine a more representative composition of soil gas.
