Product Description
The Dionex HPLC (High Performance Liquid Chromatography) system is a powerful tool used to separate and analyze a wide range of compounds. It combines high-pressure pumps, specialized columns and detectors to ensure the highest quality results. This system can be used to separate and analyze proteins, peptides, carbohydrates, pharmaceuticals, and other complex molecules. It is used in many industries including pharmaceuticals, environmental, biotechnology, and food analysis.Flexible Detection OptionsWith both variable wavelength UV/Vis and Diode Array Detectors (DAD), the Dionex Ultimate 3000 Series enables comprehensive optical analysis. The wide detection range (UV: 190600 nm) suits diverse compound classes, boosting analytical confidence across different applications.
Advanced Gradient and Flow ControlThis HPLC system supports linear, isocratic, step, and multi-step gradients with flow rates ranging from 0.001 to 10.000 mL/min. The quaternary or binary gradient pump ensures high reproducibility and adaptability for complex separations, while maintaining flow accuracy and operational stability.
Precise and Reliable PerformanceAchieve injection precision below 0.3% RSD and low detector noise (<10 AU) for trace-level analysis. An integrated auto-optimization feature and optional tray cooling (440C) provide consistent, reproducible results for even sensitive analytes.
FAQs of Dionex HPLC:
Q: How does the variable wavelength UV/Vis and DAD detection benefit my analysis?
A: The combination of UV/Vis and Diode Array Detection (DAD) provides both sensitivity and spectral profiling. This allows users to detect and identify a broad range of compounds with high confidence, capture peak purity information, and ensure accurate quantification for multi-component samples.
Q: What processes can be handled by the Dionex Ultimate 3000 HPLC system?
A: This HPLC system is suitable for analytical, pharmaceutical, chemical, food, and environmental analyses. It covers routine testing, method development, impurity profiling, stability studies, and trace contaminant detection, offering flexibility for a range of laboratory needs.
Q: When should I use the integrated sample cooling tray?
A: Use the sample cooling tray when analyzing temperature-sensitive samples or when working in environments where ambient temperatures may affect sample stability. The optional tray maintains samples between 440C, preventing degradation prior to injection.
Q: Where can this HPLC system be integrated and what are its connectivity options?
A: The Dionex Ultimate 3000 Series is designed for seamless integration into modern laboratories. It offers Ethernet, USB, and RS-232 communication ports and is fully compatible with the Chromeleon Chromatography Data System (CDS) for efficient data handling and remote operation.
Q: What are the key benefits of programmable quaternary gradient pumping?
A: Programmable quaternary gradient pumping provides precise solvent mixing, allowing users to custom-design gradients (linear, isocratic, step, multi-step) to optimize separations. This results in better peak resolution and flexibility for a wide range of analytical methods.
Q: How does the system ensure accurate and reproducible injections?
A: The system delivers injection precision of less than 0.3% RSD and utilizes corrosion-resistant stainless steel and inert polymer flow paths. Auto-optimization features and robust engineering ensure each analysis meets stringent reproducibility and reliability criteria.
