Enhancing Your HPLC Experience with KNAUER Accessories and Add-Ons

High-Performance Liquid Chromatography (HPLC) is a pivotal technique in analytical chemistry, enabling precise separation, identification, and quantification of compounds. At GMI, we proudly offer a range of KNAUER HPLC accessories and add-ons designed to elevate your laboratory’s analytical capabilities. Here’s a closer look at critical components that can enhance your HPLC system’s performance and efficiency.

Detectors: Precision and Versatility

Detectors are critical in HPLC systems, capturing signals that accurately identify and quantify compounds. KNAUER offers a variety of detectors, each tailored to specific analytical needs:

• UV Detectors: KNAUER’s UV detectors, like the BlueShadow UV/VIS Detector 40D, provide high sensitivity and excellent linearity, making them ideal for trace analysis.
• Refractive Index (RI) Detectors: These are perfect for analyzing compounds that do not absorb UV light, such as sugars and polymers. The AZURA RI Detector 2.1L offers exceptional stability and sensitivity.
• Diode Array Detectors (DAD): DADs, like the AZURA Detector DAD 6.1L, collect data at multiple wavelengths simultaneously, enabling comprehensive spectral analysis and enhanced peak purity assessment.
• Evaporative Light Scattering Detectors (ELSD): KNAUER’s ELSDs are essential for non-UV-absorbing compounds, providing reliable detection based on light scattering.

Pumps: Consistent and Accurate Flow

The efficiency of an HPLC system heavily relies on its pump. KNAUER’s pumps are designed for precision and reliability:

• Isocratic Pumps: These pumps maintain a constant mobile phase composition, which is ideal for routine applications.
• Gradient Pumps: For complex mixtures, gradient pumps like the BlueShadow Pump 80P allow for varying the mobile phase composition, enhancing separation efficiency with programmable gradient profiles

Auto-samplers: Automation and Efficiency

Auto-samplers automate the injection process, enhancing throughput and consistency:

• Increased Throughput: KNAUER’s auto-samplers enable continuous sample loading, reducing downtime between injections.
• Sample Preservation: Automation minimizes human error, ensuring consistent injection volumes and precise sample delivery.
• Software Integration: Modern auto-samplers often include software that tracks samples, ensuring robust data management and traceability.
