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 ...

Binary vs. Quaternary: Which Pump is Right for You?
How to decide which chromatography system pump is right for you Well, you’ve made it this far and I am guessing that you are coming back because I have provided some useful information to help you understand the differences and nuances of a binary versus quaternary solvent manager for a liquid chromatography instrument. This final chapter will help you think of some questions to ask when ...

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 ...

Binary vs. Quaternary Pumps: High Pressure Mixing vs. Low Pressure Mixing
Welcome to the next installment in my series on binary vs. quaternary pumps for liquid chromatography! In my previous post, I discussed how gradients are created as well as the importance of having accuracy and precision in your gradient. Today I am going to talk about what happens after all that — specifically, mixing. After chromatographic instrument’s pump or the proportioning ...

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 ...

The development of cation-exchange chromatography in free amino acids analysis
Although it was not called a liquid chromatograph, the first such instrument was introduced in late 1959 by Beckman Instruments and was designated the M.S. Amino Acid Analyzer in honour of Moore and Stein. Inject valves had yet to be invented, the buffer switching valves were glass stopcocks and the column temperature was controlled by circulating water baths. Two positive displacement pumps ...
