Ion Chromatography

Lab Expo ion chromatography systems include a modular design that allow for more flexibility. They changed the circuit technology to boost performance. These systems provide automated standard dilution functions. They include user-friendly controls and USB connection. We equip these systems with eluent generators and low-pressure degassing technology. They use bipolar conductivity detectors and gradient elution methods. Our ion chromatography systems have automated self-regenerating suppressors and advanced workstations for simple use.

FAQ for Ion Chromatography

1: What are the performance benefits of incorporating advanced circuit technology in Ion Chromatography systems?

Advanced circuit technology enhances the performance of ion chromatography systems by improving signal stability, reducing electronic noise and increasing sensitivity. These improvements lead to more accurate and reproducible detection of ions, especially at low concentrations.

2: How does using an eluent generator benefit the consistency of chromatographic results?

Eluent generators ensure precise and reproducible eluent concentration, improving method consistency and reducing variability between runs.

3: How does degassing improve system performance and reliability?

Low-pressure degassing technology removes dissolved gases from the eluent, effectively preventing the formation of gas bubbles within the flow path. This leads to a more stable baseline signal, minimizes the risk of flow interruptions and ensures consistent detector performance.

4: What is gradient elution in Ion Chromatography?

Gradient elution involves gradually changing the eluent concentration or composition during the chromatographic run to improve separation efficiency and resolution of complex mixtures.

5: Are these systems suitable for both routine and research applications?

The integration of self-regenerating suppressors with advanced workstations makes the system highly versatile offering reliable performance for both high-throughput routine testing and complex research applications.
