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.

[To the owners of parking lots and parking lot construction companies] "I'm worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those facing sidewalks or roadways are particularly prone to dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surroundings with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Vehicle Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.
