Capillary Columns Introduction Alltech Capillary Columns What do I need to consider when selecting a GC column? Internal diameter - Selection is based on sample concentration and instrumentation. Narrow bore( ) are ideal for MS, 5382. and wide bore (.53mm) are ideal for purge and trap applications. Film thickness - Film thickness has a direct affect on retention of the compound. A thicker film thickness retains the compound longer, and a thinner film decreases retention. Column Length - The column length affects both the resolution and the rate of analysis. A. longer column provides better resolution, but doubling the column length will double the time of analysis(isothermal conditions).

3 Stationary Phase - The most important consideration is the stationary phase; this is dependent upon the polarity of the compound, property of the column, and standard methods referenced, - All Alltech columns are presented with their USP designations to help you easily make a selection. - The GC Application Section (p. 522-556) offers proven methods for for a complete listing. - Questions on stationary phase selection? Call Technical Service; we are ready to assist you with your application questions. Alltech Capillary Column Families Econo-Cap Capillary Column Line Heliflex Capillary Column Line Best value in capillary columns anywhere High performance individually tested columns Batch tested to dramatically reduce price Choice of 5" or 7" rugged cage Ideal for aggressive applications Most complete selection of phases Available in the most popular phases Custom columns available to suit your specific application We've taken our most popular capillary columns and perfected the manufacturing procedure to the Heliflex Capillary Columns are manufactured from point that reproducibility is assured.

4 This allows us to the highest quality polyimide coated synthetic fused test these columns in batches instead of individually, silica. They are mounted on a rugged wear-resistant while still offering an unconditional guarantee. Batch cage. Each Heliflex Column is individually tested to testing significantly reduces cost in production without guarantee column performance and comes with a test sacrificing quality. chromatogram, instruction manual, capillary end caps, Each Econo-Cap Capillary Column comes with a copy and a free ceramic column cutter. of the batch test results, an instruction manual, and Note: Column nuts and ferrules are not included.
