A GC-MS is usually designed to be left on and ready for use at any time. However,there are occasions where the GC-MS may have to be shut down for one reason orthe other. In parts of Africa where power outages are common, the GCMS istypically shut down after the day’s work and sometimes left shut …
The atomizers most commonly used nowadays are (spectroscopic) flames and electrothermal (graphite tube) atomizers. Other atomizers, such as glow-discharge atomization, hydride atomization, or cold-vapor atomization, might be used for special purposes. Flame atomizersThe oldest and most commonly used atomizers in AAS are flames, principally the air-acetylene flame with a temperature of about 2300 °C and the …

Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture. In preparative chromatography, GC can be used to prepare pure compounds …
If you’re new to Gas Chromatography and looking for some helpful tips, here are 8 common mistakes you’ll want to avoid: Incorrect gas flow rates to a flame ionization detector If the flow rates are not correct the FID can give an incorrect response for a sample. The gas flow rate to the detector should be …
Basic Carbon Monoxide Facts Carbon monoxide (CO) is an odorless, colorless, tasteless gas that is slightly lighter than air. It is sometimes called carbonic oxide, exhaust gas or flue gas. It becomes a liquid under high pressure. It can also kill within minutes in high concentrations. Where Does Carbon Monoxide Come From? Carbon monoxide is produced …
Gas management is important for gas chromatography systems (GC) for both analytical and practical considerations. Looking after the gas supply helps to ensure accurate results, and to reduce costs and downtime. Gas Cylinders Never allow gas cylinders to run dry. As the gas pressure in the cylinder drops, the chance that contaminants (like water or …
