Performance Overview of the Waters e2695 HPLC System

Core Separation Module
As the central component of the Alliance HPLC series, the Waters e2695 features a quaternary gradient pump system with digitally controlled linear-drive pistons and dual pressure sensors, delivering pulse-free mobile phase flow (flow rate range: 0.001-10 mL/min, increment: 0.001 mL/min). With a delay volume <650 μL (pressure-independent) and gradient precision of ±0.15% RSD, it supports 11 gradient profiles (including linear/step/concave/convex), fully compliant with USP/EP pharmacopeia requirements.

Intelligent Sample Management
The 120-position autosampler provides:

• Ultra-micro injection (0.1-100 μL standard, expandable to 2 mL)
• Low carryover (<0.0025% via programmable needle wash)
• Temperature control (4-40℃ sample compartment, ±0.1℃ accuracy)
  Injection linearity (R²>0.999) and precision (<0.5% RSD) ensure reliable trace analysis.

Detector Compatibility
Seamless integration with:

• 2489 UV/Vis detector (190-700nm, dual-wavelength synchronous detection)
• 2475 FLR detector (EX 200-890nm, EM 210-900nm, S/N>1000)
• 2414 RID (for saccharides/polymers)
• MS interfaces (ACQUITY QDa compatible).

Key Innovations

1. CORTECS 2.7μm columns: Bridges HPLC-UPLC performance gap with 30% efficiency gain
2. Empower 3 software: 21 CFR Part 11 compliant with method transfer and audit trail
3. Regulatory readiness: SQT tools streamline GMP/GLP validation.

Applications
Excel in pharmaceuticals (dissolution/assay), food safety (pesticides/additives), and environmental (PAHs) analyses—particularly for thermolabile compounds (e.g., proteins/vitamins). Current secondary market price ~¥300K offers superior cost-performance versus new systems.

Industry-Specific Rendering:

• Maintains Waters' trademark terminology (e.g., "ACQUITY", "Empower")
• Preserves metrological symbols (μm, ℃, nm) per ISO 80000
• Uses active voice for SOP readability ("delivers", "provides", "ensures")
• Aligns with USP <621> chromatography guidelines

Alternative Technical Phrasing:
"The quaternary solvent delivery system achieves ±1% compositional accuracy at 1.0 mL/min under 6000 psi backpressure, as per ASTM E685 method validation standards."
