Innovation of Restek Biphenyl Columns: 20 Years of Excellent Selectivity and Separation Performance

A fixed phase with a long history! A product that expands the possibilities of selectivity and retention.

"Raptor Biphenyl" is a stationary phase suitable for applications in biological sample analysis, such as drug and metabolite analysis. It allows for improved selectivity and retention for compounds that are difficult to retain or separate using C18 or other phenyl stationary phases. It can be used with simple mobile phase conditions suitable for mass spectrometers. 【Features】 ■ Improved selectivity and retention for compounds that are difficult to retain or separate ■ Suitable for applications in biological sample analysis, such as drug and metabolite analysis ■ Can be used with simple mobile phase conditions suitable for mass spectrometers ■ Using a methanol mobile phase expands the possibilities for selectivity and retention that cannot be achieved with common stationary phases *For more details, please refer to the PDF document or feel free to contact us.

• Separation device

A variety of stationary phases and particle sizes! LC columns with better selectivity that improve separation efficiency.

Restek's "Raptor LC Column" is a highly efficient LC column that significantly reduces analysis time. It includes options suitable for biological sample analysis, such as the "Raptor Biphenyl Column" for drug and metabolite analysis, as well as the "Raptor ARC-18 Column." It offers better selectivity that improves resolution and sustainable reproducibility. 【Features】 ■ High efficiency that significantly reduces analysis time ■ Better selectivity that improves resolution ■ Improved sample throughput with existing HPLC and UHPLC ■ Sustainable reproducibility ■ A variety of stationary phases and particle sizes *For more details, please refer to the PDF document or feel free to contact us.

• Other inspection equipment and devices

Restek's 100% pure satisfaction guarantee! Compatible with high-pressure fast analysis using UHPLC.

Restek's "Force Performance LC Column" is a product that can increase productivity by maximizing the operating time of the equipment. It is designed to easily transfer methods from HPLC to advanced UHPLC and to withstand high pressure and severe pressure fluctuations. Whether using columns with particle sizes of 3μm or 5μm in a typical HPLC system, or using columns with a particle size of 1.8μm in a new UHPLC, it consistently provides the same separation. 【Features】 ■ Durability and reproducibility ■ Compatibility between HPLC and UHPLC ■ High quality *For more details, please refer to the PDF document or feel free to contact us.

Thank you very much for your continued support. Donaldson Japan Co., Ltd. will be closed during the following period: From April 25 (Saturday) to May 6 (Wednesday). Inquiries made during the closure will be answered sequentially after May 7 (Thursday). We sincerely apologize for any inconvenience this may cause. Thank you for your understanding and cooperation.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
