Gemini

Product Details Ordering Information Download Materials Related video Application Cases

Gemini series is a durable reversed-phase HPLC stationary phase that offers longer column life under extreme pH conditions, with stable reproducibility and efficient separation.

  • Make full use of high and low pH conditions (pH 1-12) to adjust selectivity. 
  • Use TWIN-NX™ technology to give the column a longer lifespan. 
  • Suitable for analysis and preparative separation of both acidic and basic compounds.

 

Gemini C8(3) is the third-generation innovative LC filler. It uses a silicone hybrid process to achieve a uniform and stable ethyl cross-linking on the particle surface. This helps resist high pH dissolution without affecting the mechanical strength and efficiency of the internal silica matrix.

 

 

Many products can be used to separate human insulin and its degradation products, but few can withstand the high pH alkaline washes needed to remove aggregates. Now, that’s no longer a problem. Gemini C8(3) can achieve the separation you need while also being stable at both high and low pH, maintaining overall column efficiency and retention consistency even with repeated use. You don’t have to choose between consistent performance and stability—Gemini C8(3) lets you have the best of both worlds.

 

 

Gemini 10 μm C8(3) is a packing material designed by Phenomenex specifically for insulin purification. It ensures high reproducibility and sample load through multiple quality controls carried out throughout the entire production process.
