I.Overview
Deionized water (DI water) equipment plays the role of an “invisible guardian” in the preparation of basic reagents. Its core value lies in eliminating ion interference and ensuring reagent stability and batch-to-batch consistency. The golden rules for using DI water in basic reagents are: zero ions, economic priority, upgrade as needed, and intelligent water conservation.
II.Economical and Efficient Configuration (Applicable to 90% scenarios)
Raw Water → Sand Filtration + Activated Carbon → Softener → Single - stage RO (Reverse Osmosis) → Mixed - bed Resin → DI (Deionized) Water Tank
III.Types of Basic Reagents and DI Water Requirements
| Reagent Category | Core Water Quality Indicators | ||||
| General Buffer Solution | Resistivity ≥ 1 MΩ·cm | ||||
| Indicator Solution | TOC < 100 ppb | ||||
| Cleaning Agent (e.g., Laboratory Cleaning Solution) | Hardness = 0 (Ca²⁺/Mg²⁺ = 0) | ||||
| Standard Acid - Base Dilution Solution | Controllable CO₂ Dissolution (Conductivity Change < 1%) | ||||
| Precipitant (e.g., Ammonium Sulfate) | Cl⁻ < 0.5 ppm |
IV.Applicable scenarios
Teaching laboratories
Factory quality control rooms
Environmental protection testing stations
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 )
