Gas chromatography - What are Columns?
Liquid and gas chromatography instruments wouldn't work without columns. Both liquid and gas chromatography analyze samples by separating them into their individual chemical components. A column, a long tube lined with specialized chemicals, is required for this process as it forms part of the instrument which performs the separation. When a sample makes its way through the tube, certain ...

How does an FID work?
An FID, or Flame Ionization Detector, is the most common detector paired with gas chromatography instruments for analytical applications. But how does and FID work? An FID uses a flame to ionize organic compounds containing carbon. Following separation of the sample in the GC column, each analyte passes through a flame, fuelled by hydrogen and zero air, which ionises the carbon atoms. ...

Using a hydrogen generator for GC-FID in FLNG facilities
Gas-fired electrical power is now a growing energy market in Japan, following the 2011 Tahoku earthquake and tsunami which led to the Daiichi nuclear disaster. Having caused tremendous damage to local communities and farm produce, a number of private companies have been tapping into different energy supply methods, leading to a surge in gas-fired electrical power generation in Japan. This has ...

US EPA Method 524.4 with the Tekmar Lumin P & T Concentrator and Thermo Scientific TRACE 1310 GC and ISQ LT MS System
Abstract US EPA Method 524.4 is used primarily by environmental labs for the analysis of volatile organic compounds (VOCs) in drinking water. While this method is effective at concentrating the trace levels of VOCs sometimes found in finished drinking water, it also tends to transfer significant quantities of water vapor to the gas chromatography-mass spectrometry instruments. Teledyne ...

Blood Alcohol Determination with the Teledyne Tekmar HT3 and Young Lin YL6500 Gas Chromatograph
Introduction Police and forensic laboratories around the world routinely use headspace-gas chromatography for volatile components in biological fluids. One of the more common headspace analyses is the determination of blood alcohol in cases involving suspected DUI or OVI. The blood alcohol limit for some countries, like Korea and South Africa, is as low as 0.05%. This study evaluates Teledyne ...

Residual Solvents Testing per ASTM F1884-04 with the Versa and HT3 Automated Headspace Sampler
Introduction Police and forensic laboratories around the world routinely use headspace-gas chromatography for volatile components in biological fluids. One of the more common headspace analyses is the determination of blood alcohol in cases involving suspected DUI or OVI. The blood alcohol limit for some countries, like Korea and South Africa, is as low as 0.05%. This study evaluates Teledyne ...

Emissions Monitoring through Long-term Sampling
Emissions monitoring is often carried out by continuously operating instruments providing measurement results in close-to real time. The data can then be averaged and compared to emission limits. Using this kind of instruments is not only a possibility but often a legislative requirement. This is often the case for many of the “usual suspects” such as NOX, SO2, CO, NH3, HCl, and dust, ...

US EPA Method 624 with the Tekmar Lumin P&T Concentrator and the Thermo Scientific TRACE 1310 GC and ISQ LT MS
Abstract US EPA Method 624 is used primarily by environmental labs for the analysis of volatile organic compounds (VOCs) in wastewater. While this method is effective at concentrating the trace levels of VOCs sometimes found in water, it also tends to transfer significant quantities of water vapor to gas chromatography-mass spectrometry (GC-MS) instruments. To reduce the amount of water ...
