YMC-Triart Prep

Robust and pH Stable Hybrid Silica Process Material

YMC-Triart Prep

    Particle Technology

    With YMC-Triart Prep, a pH stable preparative grade HPLC stationary phase gets available. This hybrid material can be produced in lot sizes of up to several hundred kg. It is well suited for production scale applications, as it is available up to multi-ton scale.

    YMC-Triart Prep is chemically stable up to pH 10.0. This provides more flexibility for method development and also allows for more efficient cleaning-in-place (CIP) procedures. From real life process development work YMC-Triart Prep has been shown to outperform traditional silica-based materials in terms of durability up to 4-fold. Longer column lifetimes lead to greater amounts of product being produced per kilogram of stationary phase. The results are: improved production procedures and reduced overall costs.

     

    Mechanical Stability Test

    Shearing and crushing of silica particles during repacking of columns leads to the formation of fines which results in increased backpressures. By using mechanically stable, spherical particles the formation of fines can be reduced.

    Here, the high mechanical stability of YMC-Triart Prep is demonstrated by means of repeated packing and unpacking of a DAC column. Even after more than 10 repacking cycles for the same material the pressure does not increase. The absence of fines is shown by the constant backpressure. This makes YMC-Triart Prep a valuable phase for method development and especially for process optimisation!

    Cleaning in Place

    In a production process, repeated injections of a solution of insulin in human plasma/serum are carried out. Consequently, absorption of protein and other impurities to the surface of the packing material reduces the retention capacity of the column.

    Methodology: At this point a wash step with an alkaline solution (e.g. 0.1 M NaOH) removed the impurities and restores the full capacity of the column.

    Problem: Silica materials are unsuitable for alkaline wash conditions, because of their poor stability at high pH.

    Solution: Hybrid silica based YMC-Triart Prep has an excellent stability at high pH. It is stable to alkaline wash conditions which enables longer column lifetime.

    This in turn reduces production costs: Lower consumption of packing material and less downtime due to column repacking. An extension of column lifetime by a factor of > two has been achieved!

    Purification of Insulin with YMC-Triart Prep C8 (experimental study by major pharm. company)

    The efficiency of a preparative purification depends on the selectivity of the stationary phase and its ability to separate possible impurities from the main product. An increase in selectivity would not only improve the degree of separation of the peaks, but also reduce the cleaning costs by increasing the load on the column. Furthermore, the amount of sorbent and consumption of mobile phase could be reduced to increase the yield for a given capacity or to improve the product quality.

    With YMC-Triart the output could be increased at the same time as reducing costs.

    Considering the overall costs, the proposed costs to obtain 1 kg insulin (purity ≥ 98.5%, starting from an initial purity 96.5%) with YMC-Triart Prep C8-L and appropriate solvents are 19% lower than with Daisogel SP-120-10-C8-BIO. In terms of process economy YMC Triart Prep C8-L scores the lowest overall purification costs and lowest absolute costs of the stationary phase. The amount of sorbent costs represents only about 1.7% of the overall costs, which is also the lowest percentage of all phases used.

    Homogeneous and uniform Particles

    YMC-Triart Prep is produced using micro-reactor technology in the bead formation process. This results in spherical particles with a highly uniform particle and pore size distribution which contributes to a reduction of the backpressure and to more reproducibility in surface modification.
