一般描述

对于不需要玻璃惰性的低要求应用，应使用经济型的金属柱。该色谱柱具有一般性配置，并可小心将其弯曲以适用于大多数仪器。
Packed column made up of stainless steel are basically used when higher carrier gas flow rates are employed as they can sustain elevated pressure. Stainless steel columns are usually washed with dilute hydrochloric acid, then with water followed by methanol, acetone, methylene dichloride and n-hexane in order to remove any corrosion products and traces of lubricating agents.

应用

Porapak Q packed in a stainless steel gas chromatographic column maybe used for the oxidation reduction experiments in order to design the appropriate surface sites for ruthenium-ceria catalysts supported on graphite by controlled preparation method.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How do I properly condition Product No. 13979-U, SS Column 10ft General Coil 80/100 Porapak Q?

    Polymers continuously shrink with heat due to loss of residual monomer. If conditioned too harshly, rapid loss of residual monomer results in gaps through the column.  By mildly conditioning the polymer packing, it helps to decrease the number and size of voids due to shrinkage of the polymer.   Below is a suggested conditioning procedure for polymer packed columns.  Ramp rate is not important compared to the temperature for the analysis.  Flow rate of 5-20 deg C/minute can be use if desired, once the column has been conditioned.  120 deg C for 4 hours  160 deg C for 4 hours  180 deg C for 4 hours  200 deg C for 4 hours  220 deg C for 4 hours  @ 60 mL/minute.
