Product Description

Customizable 1000 liters/h ultrapure water filtration system for mobile phase preparation for precision instruments


Overview
The 1000 L/H ultra pure water treatment system is designed to provide high-purity water for mobile phase preparation in precision analytical instruments, such as HPLC, LC-MS, ICP, and other laboratory or analytical applications.
The system adopts advanced purification technologies including pre-treatment, reverse osmosis, EDI (Electrodeionization), and polishing purification, ensuring stable production of ultra-pure water that meets the stringent requirements of precision instruments and laboratory analysis.


Process
Raw Water → Raw Water Pump → Multi-Media Filter → Activated Carbon Filter → Water Softener → Security Filter → First-Stage RO → Intermediate Tank → Second-Stage RO → EDI System → Polishing Mixed Bed → Ultra-Pure Water Tank → Circulation Pump → UV Sterilizer → 0.22 μm Terminal Filter → Point of Use


Main System Components

1. Pretreatment System

  • Multi-media filter for removing suspended solids and turbidity

  • Activated carbon filter for removing chlorine, organic matter, and odor

  • Water softener for reducing hardness and preventing membrane scaling

2. Reverse Osmosis System

  • Two-stage reverse osmosis system for high-efficiency desalination

  • Removal of dissolved salts, heavy metals, and microorganisms

3. EDI System

  • Continuous electrodeionization technology

  • Produces high-purity water without chemical regeneration

  • Stable operation and low operating cost

4. Polishing Mixed Bed

  • Further removal of trace ions to achieve ultra-low conductivity

  • Ensures ultra-pure water quality for sensitive analytical instruments

5. Storage and Distribution System

  • Ultra-pure water storage tank (food-grade PE or stainless steel)

  • Circulating distribution loop with UV sterilization and terminal filtration


Specific requirements for mobile phase preparation

Parameter Requirement
Resistivity ≥ 18.2 MΩ·cm @ 25°C (basic); Stringent limits for trace anions (Cl⁻, SO₄²⁻, NO₃⁻) and cations (Na⁺, K⁺, NH₄⁺, Ca²⁺, Mg²⁺) for ion chromatography
TOC <5 ppb (general); < 3 ppb (strongly recommended for RPLC, LC - MS/MS); < 1 ppb (ideal)
Particles ≤ 0.2 µm filtration or lower; < 1 particle/mL (> 0.2 µm)
Microorganisms < 1 CFU/mL
Specific Contaminants Ultra - low levels of ions (e.g., Cl⁻ for phosphate analysis), heavy metals, silica; No colloidal silica
Key technology Double-pass Reverse Osmosis + EDI

Application Areas
This system is widely used in laboratories and industries requiring high-purity water, including:
• Mobile phase preparation for HPLC and LC-MS
• Precision analytical instruments
• Pharmaceutical laboratories
• Chemical analysis laboratories
• Semiconductor and electronics testing


V.Here is a guideline for you to get a proper quotation
Tell us the raw water/source of water(tap water, well water, or sea water, etc)
Provide water analysis report(TDS , conductivity, or resistivity, etc)
Required production capacity( 5m³/H, 50m³/H,or 500m³/H, etc)
What's the pure water used for( industrial,Food and Beverage,or agriculture, etc )
