  5. When are additional phases expected for Titan 1.9μm columns?

    Additional Titan 1.9μm phases are being developed and will encompass all aspects of UHPLC requirements.

  6. Can I use Titan 1.9 μm columns on HPLC systems?

    Titan 1.9 μm columns are designed to be used only on UPLC or UHPLC systems.

  7. Which UHPLC Instruments can be used with Titan?

    Titan 1.9μm columns can be used on any UPLC or UHPLC System.

  8. What is the best practice for long-term storage of Titan C18 1.9 μm columns?

    Long-term storage of silica-based, reversed-phase columns is best in 100% acetonitrile. Columns may be safely stored for short periods (up to 3 or 4 days) in most common mobile phases. However, when using buffers, it is best to protect both the column and the HPLC equipment and remove any salts by flushing the column with the same mobile phase without the buffer (e.g., when using 60:40 ACN:buffer, flush the column with 60:40 ACN:H2O) to eliminate any danger of corrosion from the salts while providing rapid reequilibration of the column with the original mobile phase. Before storing the column, the end-fittings should be tightly sealed with the end-plugs that are provided with the column to prevent the packing from drying.

  9. What solvents are compatible with Titan C18 1.9 μm columns?

    Water and all common organic solvents are compatible with Titan C18 1.9 μm columns.

In a previous report, it was reported that columns packed with fully porous 1.9μm Titan-C18 particles provided a minimum reduced plate height as small as 1.7 for the most retained compound (n-octanophenone) under RPLC conditions. These particles are characterized by...

The mass transfer mechanism in four prototype columns (2.1 and 3.0×50mm, 2.1 and 3.0×100mm) packed with 1.9μm fully porous Titan-C18 particles was investigated by using two previously reported home-made protocols. The first one was used to measure the eddy dispersion...
