2023年9月4日 · Liquid Chromatography (LC) and Gas Chromatography (GC) are two distinct analytical techniques used for the separation and analysis of compounds in complex mixtures. …

2023年8月21日 · Chromatography is classified into two types based on the physical state of the mobile phase used – liquid chromatography (LC) and gas chromatography (GC).

Gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) are two powerful analytical techniques used in the field of analytical chemistry. Both …

2024年3月3日 · Gas chromatography (GC) involves vaporizing samples and passing them through a column with a carrier gas, allowing separation based on volatility. Liquid …

2017年7月30日 · In order to identify and account for all substances in a particular difficult sample or mix, LC-MS or GC-MS can be used to ease and hasten the identification process. “LC-MS” …

2012年3月6日 · Practical advice, tutorials, and peer-reviewed research on liquid chromatography (HPLC), gas chromatography (GC), mass spectrometry (MS) and related techniques.

2024年8月23日 · LC uses a liquid mobile phase, making it suitable for larger, non-volatile molecules, whereas GC employs a gaseous mobile phase, ideal for small, volatile compounds. …

The GC part of a GC-MS, termed the chromatograph, generates a plot called a chromatogram. The chromatogram is a graph showing amount of molecules on the y axis and time on the x …

GC-MS is primarily used for volatile and semi-volatile compounds, as it requires the sample to be in the gas phase. On the other hand, LC-MS is suitable for a wider range of compounds, …

In liquid chromatography (LC), the flowing or mobile phase is a liquid, whereas in gas chromatography (GC) is a gas. Detection of the separated components in both GC and LC can …
