Sample preparation is essential when employing chromatography for bioanalytical analysis as system performance will be negatively affected if it is not performed. Preparation methods include protein ...

Ultra-fast gas chromatography means analysis cycle times are decreasing so the time to prepare the samples to be analysed is becoming the limiting factor, according to an instrument provider. Ellutia ...

Gas chromatography (GC) is best suited for the analysis of volatile or gaseous compounds. Ideally, a liquid sample or its vapor would be directly introduced into the injection port. But to analyze the ...

Solid-phase extraction has several advantages over liquid/liquid extraction for extractables and leachables studies. An extractable/leachable (E/L) study is routinely performed on the materials ...

As interest in essential oils (EOs) for their therapeutic, antibacterial, and antifungal properties continues to grow—driving demand for high-quality products in both medicinal and industrial ...

Evaporation is an endothermic process undertaken by all liquids. This physical state change occurs when surface molecules gain sufficient kinetic energy to overcome the enthalpy of vaporization. Such ...

In this case study of amines, the authors discuss several parameters to be considered in developing a headspace GC method. Headspace gas chromatography (GC) has been used since the 1980s, but only ...

Do you know a back-pressure regulator from a macroporous resin? If you’re new to chromatography, the Chromatography and Sample Preparation Terminology Guide is a nice, simple resource to quickly ...

Gas chromatography (GC) is best suited for the analysis of volatile or gaseous compounds. Ideally, a liquid sample or its vapor would be directly introduced into the injection port. But to analyze the ...
