Researchers proposed a new lab workflow using gas chromatography and computer vision to help identify the geographic origin ...

We established an ex-situ technique for evaluating hydrogen gas permeability by thermal desorption analysis (TDA) gas chromatography (GC) and by self-developed diffusion analysis software. Absorbed ...

Formaldehyde (HCHO) is a human toxin that is both a pollutant and endogenous metabolite. HCHO concentrations in human biological samples are reported in the micromolar range; however, accurate ...

Chromatography is one of science’s most powerful tools, yet many of its breakthrough capabilities remain hidden in plain sight. When you truly understand the fundamentals, you unlock performance most ...

Regulatory expectations under EC 1935/2004 require attention to migrants from food-contact materials, yet “bio-based” ...

Analysts interested in quantifying volatile organic compounds like disinfection byproducts in liquid samples should consider using the gas chromatography system. There are two gas chromatography (GC) ...

Gas chromatography was discovered by Russian-Italian botanist, Mikhail Semyonovich Tsvet, in the early 1900s. The separation technique is used to first split the chemical components of a mixture, then ...

Most gases are extremely difficult to detect because they are odorless. Certain gases are extremely harmful to humans if inhaled. Owing to the above, researchers have developed many potent techniques ...
