1. Basic Information of the Instrument

Name: High Performance Liquid Chromatography

Serial Number: 1900544S

Model Number：WATERS Alliance e2695

Manufacturer: WATERS

2. Specifications and Technical Indicators

2.1. Pump: the independent linear motor drive and dual pressure sensors without dampers and mixers can reduce the dead volume of the system, make the instrument baseline stable, sharpen and narrow chromatographic peaks, and improve detection sensitivity.

2.2. Number of Flow Paths of Solvent: 4 (quadruple).

2.3. Flow Rate Range: 0-10ml/min, 0.001ml/min step-by-step adjusting.

2.4. Flow Rate Precision: <0.075% RSD.

2.5. Flow Rate Accuracy: +1%.

2.6. System Volume: <650ul, no change with counter pressure.

2.7 Gradient Curves: 11 curves (one straight line, two stepping lines, four convex lines, four concave lines) are equipped with the instrument, so there is no need to edit them. They can become complex gradients to analyze complex samples.

3. Main Accessories and Configuration

Auto sampler:

1) Number of Vials: ≥120, 5 independent sample trays (24 samples per tray).

2) Injection Precision: <0.3% RSD.

3) Injection Linearity: >0.999.

4) Injection Volume: 0.1-100ul; expandable up to 2,000ul.

(5) Temperature Control Range: indoor temperature-60 ℃.

(6) Automatic cleaning of the inner and outer wall of injection needle to avoid cross-contamination of samples.

4.Function and Usage

High performance liquid chromatography analysis of the content and nature of small molecules.

5. Place

Room 213 of Public Platform for Experimental Instruments of State Key Laboratory of Marine Resources Utilization in the South China Sea (MRU)
