2. Size-exclusion chromatography - Wikipedia

   en.wikipedia.org/wiki/Size-exclusion_chromatography

   Proper column packing is important for maximum resolution: An over-packed column can collapse the pores in the beads, resulting in a loss of resolution. An under-packed column can reduce the relative surface area of the stationary phase accessible to smaller species, resulting in those species spending less time trapped in pores.

3. Whatman plc - Wikipedia

   en.wikipedia.org/wiki/Whatman_plc

   Whatman plc is a Cytiva brand specialising in laboratory filtration products and separation technologies.. Whatman products cover a range of laboratory applications that require filtration, sample collection (cards and kits), blotting, lateral flow components and flow-through assays and other general laboratory accessories.

4. Random column packing - Wikipedia

   en.wikipedia.org/wiki/Random_column_packing

   Random column packing is the practice of packing a distillation column with randomly fitting filtration material in order to optimize surface area over which reactants can interact while minimizing the complexity of construction of such columns. Random column packing is an alternative to structured column packing.

5. DC100 - Wikipedia

   en.wikipedia.org/wiki/DC100

   DC100 (also known as DC100A) is a tape cartridge format that was co-developed by Hewlett-Packard and 3M. [1] Introduced in mid-1976, [2] it was developed as a data storage mechanism for the HP 9820 programmable calculator. [3]

6. Monolithic HPLC column - Wikipedia

   en.wikipedia.org/wiki/Monolithic_HPLC_column

   Monolithic in situ polymerization avoids the primary source of column to column variability, which is the packing procedure. [4] Additionally, packed particle columns must be maintained in a solvent environment and cannot be exposed to air during or after the packing procedure.

7. Chromatography column - Wikipedia

   en.wikipedia.org/wiki/Chromatography_column

   Chromatography columns of different types are used in both gas and liquid chromatography: Liquid chromatography: Traditional chromatography columns were made of glass. Modern columns are mostly made of borosilicate glass, acrylic glass or stainless steel. To prevent the stationary phase from leaking out of the column interior a polymer ...
