General Column Specs
   Column Type:       
   Your choices are...         
   Packed Column       Packed GC columns are typically of glass or stainless steel coil construction. They are generally one to five meters in total length with an inner diameter of five millimeters.  These devices are filled with a stationary phase, or packing coated with the stationary phase. 
   Capillary Column       Also known as Open Tubular.  Capillary GC column is comprised of two major parts - tubing and stationary phase. A thin film (0.1-10.0 micro meters) of a high molecular weight, thermally stable polymer is coated onto the inner wall of small diameter (0.05-0.53 mm I.D.) tubing. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Capillary Column Type:       
   Your choices are...         
   Support Coated Open Tubular (SCOT)       The inner wall of the capillary is lined with a thin layer of support material such as diatomaceous earth onto which the stationary phase has been adsorbed. 
   Porous Layer Open Tubular (PLOT)       Capillary columns where the stationary phase are based on an adsorbent or a porous polymer. 
   Wall Coated Open Tubular (WCOT)       Wall-coated columns consist of a capillary tube whose walls are coated with liquid stationary phase. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Construction Material:       
   Your choices are...         
   Glass       A homogeneous material with a random, liquid-like (non-crystalline) molecular structure. The manufacturing process requires that the raw materials be heated to a temperature sufficient to produce a completely fused melt, which, when cooled rapidly, becomes rigid without crystallizing. 
   Steel - Stainless       Stainless steel is chemical and corrosion resistant and can have relatively high-pressure ratings. 
   Silicate Glass       The most common type of glass.  Often found in mixtures such as alkali-borosilicate glass, borosilicate glass, alumina silicate glass, etc. 
   Other       Other unlisted or proprietary material. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Column Length:       The length of the column. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Inner Diameter (ID):       The inner diameter of the column. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Film Thickness:       The thickness of the coating inside the column. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Operating Pressure:       Pressure range that the column will operate within. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
