Headspace Gas Determination by Gas-Liquid Chromatography Nitrogen, the principal gas normally present in canned foods during storage, is associated with lesser quantities of carbon dioxide and

Jan 01, 2002 · Chapter 10 Headspace gas chromatography Zelda E. Penton 10.1 OVERVIEW 10.1.1 Introduction Headspace gas chromatography (GC) is a sample preparation method for determining volatile compounds in solid and liquid samples. The technique has existed since the late 1950s [1] and is still actively used.

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. [1]

Plus, no makeup gas is required due to the efficient sweeping of the column effluent by hydrogen combustion gas. CS: We also redesigned PerkinElmer’s split/splitless capillary injector to improve sample transfer to the column. This greatly reduces metal catalyzed degradation of labile analytes like residual pesticides, such as dieldrin and

The TAGS is a very flexible accessory featuring full control of all gases used in thermal analysis. In addition to performing gas switching, the TAGS also fully controls the gas flow rate, independent of the type of gas, and detects rapid changes in pressure and empty cylinders.

Fused silica is considered to be the purest form of glass, with fewer metal oxides (Lewis acid sites) and hydrogen bonding (surface silanol) groups. The stationary phase is cross linked (polymerized) and also bonded to the surface of the column to provide a high degree of stability, resulting in lower bleeding of the stationary phase at

This Addition Gas Line, with 0.8 mm I.D. and 10 inch length, is for use with PFA Spray Chambers in NexION ® 1000/2000 ICP-MS series instruments. It is designed for adding 20% Oxygen/80% Argon when organic solvents are analyzed and also attaches to the AMS Spray Chamber Port.
