Metrohm 761 Compact IC Ion Chromatograph Introduction

Product Overview

The Metrohm 761 Compact IC is a high-performance compact ion chromatograph developed by Metrohm (Switzerland), designed for routine ion analysis in laboratories. It offers two configurations: chemical suppression (.0020 model) and non-chemical suppression (.0010 model), making it suitable for water and polar substance analysis in environmental monitoring, food safety, pharmaceuticals, and other fields. Its core advantages lie in its streamlined operation and modular integrated design, capable of stable operation at flow rates of 0.2–2.5 mL/min and pressures up to 25 MPa to meet high-precision detection requirements.

Core Technical Features

1. Integrated Design

   • Features a built-in 6-port injection valve, dual-piston pump, chromatographic column, MSM chemical suppression system (.0020 model only), and conductivity detector—all integrated into a compact unit measuring just 19cm × 15cm × 10cm, saving 40% lab space.
   • Equipped with a 22-bit high-precision A/D converter, detector temperature stability of ±0.01°C (range: 25–45°C), and three conductivity measurement ranges (0–50/250/1000 μS).

2. Intelligent Control System

   • Fully automated control via PC software, including chromatographic parameter configuration, online firmware updates, and real-time data processing, significantly improving analysis efficiency.
   • Optional Inline Ultrafiltration or 863 Autosampler supports unattended analysis of 36 samples, minimizing manual intervention.

3. Flexible Application Adaptability

   • Compatible with anion (e.g., Cl⁻, NO₃⁻, SO₄²⁻) and cation (e.g., Na⁺, K⁺, Ca²⁺) analysis, recommended for use with the cost-effective Metrosep A Supp 17 column.
   • The chemical suppression model (.0020) significantly reduces baseline noise, enhancing trace ion detection sensitivity.

Industry Applications & After-Sales Support

• Typical Applications:
  • Environmental water quality monitoring (compliant with standards such as GB 23200.113-2018)
  • Pharmaceutical industry purified water ion residue testing
  • Food additive and contaminant analysis.
• Service Support: Metrohm provides a 1-year full warranty, 10-year suppressor warranty, and 5-year software upgrades to ensure long-term stable operation.

Note: Some technical parameters may vary by configuration. Contact authorized distributors for model-specific details (e.g., functional differences between .0010 and .0020 models).
