In this installment, we examine several of the common parameters that can affect automated peak integration and the resulting peak areas. We will consider how the data system detects the beginning and end of the peak, how it determines the peak maximum, how real peaks are differentiated from noise, and how signals at individual time intervals are summed to generate the peak area.
A group of Taiwanese scientists have recently created a new method for assessing food quality and detecting histamine in wine samples.
During a workshop at Pittcon, David Alonso of LECO Corporation discussed how gas chromatography–time-of-flight mass spectrometry (GC-TOFMS) can be used to identify polyfluorinated alkyl chemicals (PFAS) chemicals in anti-fog product solutions.
On February 25, a Pittcon oral session, titled “Detection of PFAS and other Polyfluorinated Analytes,” took place at the San Diego Convention Center in San Diego, California. This session included six talks that covered a variety of analytical techniques currently being used in per- and polyfluoralkyl (PFAS) analysis.
At Pittcon 2024, He Nan of AbbVie gave a lecture on how to monitor N-nitrosamines via gas chromatography–electron capture detection.
A new method has been developed to provide a sensitive, accurate and convenient GC–MS method to align with the new European regulation in relation to the introduction of the new Accutrace Plus marker for fuels.
The 18th International Symposium on Hyphenated Techniques in Chromatography and Separation Technology will take place from 28–31 May 2024 in Leuven, Belgium.
Blood and sputum are the most common means of detection by diagnostic tests, but producing adequate sputum can be difficult given a dry cough is often a TB symptom.
Researchers employed advanced chromatography and mass spectrometry techniques to unravel the chemical components and metabolites of Lingbao Huxin Dan, pinpointing its therapeutic potential for cardiovascular ailments.
Distinguishing between viable and non-viable seeds requires an advanced chromatographic technique. A study conducted by researchers from China Agricultural University highlights how HS-GC-IMS can be used to help solve this frequent problem in the agricultural industry.
A polydimethylsiloxane (PDMS) silicone rubber band sampler was used to collect volatile organic compounds (VOCs) from the skin of both tuberculosis (TB)-positive and TB-negative subjects.
Alicat™ Scientific releases the next generation of OEM flow controllers and meters.
Non-alcoholic beers are becoming more popular and need to reflect the sophisticated flavourings of beers that are brewed containing alcohol. Sophisticated analytical techniques can help to achieve this.
Scientists from the University of Calgary recently developed a novel method for externally adjusting the column length during gas chromatography (GC) operation.
A recent study explored using gas chromatography (GC) to assess relative response factors in quality control measures for alcoholic beverages.
Researchers from Europe conducted the first known interlaboratory study on inverse gas chromatography (IGC), revealing significant variations in dispersive surface energy values and retention volumes for standard materials.
Gas chromatography is a premier technique for quantitative analysis. As gas chromatographs have become simpler to use and data systems more powerful, much of the data processing involved in delivering quantitative results now happens in the background and is seemingly invisible to the user. In this installment, we will review the calibration techniques used with gas chromatography. We will compare calibration methods and the assumptions that underlie them. We will explore common mistakes and challenges in developing quantitative methods and conclude with recommendations for appropriate calibration methods for quantitative problems.
This annual award is presented to an outstanding scientist in the field of chromatography.
