DIONEX Product Lines We Repair
Our engineers are trained on the full DIONEX product range. Below are the major product families we service.
ICS Ion Chromatography Systems
High-performance ion chromatography for cations and anions analysis. Common failures include pump seal degradation, conductivity detector cell fouling, and eluent generator cartridge pressure issues affecting separation precision and baseline stability.
Ultimate 3000 HPLC Systems
Modular liquid chromatography platform with UV-VIS, fluorescence, and MS detectors. Typical faults: proportioning valve stiction, autosampler needle clogging, detector lamp aging, and thermal control module failures impacting method accuracy.
Eluent Generator Systems
Water electrolysis-based eluent generation for ion chromatography eliminating chemical cartridge dependency. Recurrent issues: membrane degradation, cell voltage drift, pressure relief valve sticking, and water purity sensor faults.
Detector Modules and Electronics
Specialized detectors including conductivity, UV-VIS, fluorescence, and amperometric electrochemical sensors. Common electronic failures: pre-amplifier circuit drift, LED/lamp power supply aging, reference electrode potential drift, and data acquisition card faults.
Sample Preparation Systems
Automated solid phase extraction and sample conditioning platforms. Typical malfunctions: vacuum pump seal wear, selector valve stiction, pressure transducer drift, and solvent delivery check valve blockage.

Common DIONEX Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DIONEX equipment arriving at our workshop.
- ✓Conductivity detector baseline drift and noise — Cell fouling from salt deposits, platinum electrode degradation, or reference electrode potential shift in ion chromatography systems. Exposure to corrosive eluents and minerals in analytical samples gradually contaminates the measurement cell.
- ✓Pump seal leakage and loss of back-pressure — HPLC and IC pump seals experience mechanical wear from continuous solvent circulation, particularly when using aggressive mobile phases or operating at high pressures. Incompatible solvents cause elastomer degradation in Dionex proportioning pumps.
- ✓Autosampler needle clogging and injection failures — Particulates and precipitated salts from analytical samples block the autosampler needle tip and syringe lines in Ultimate 3000 systems. Inadequate needle wash or sample-solvent incompatibility accelerates clogging in pharmaceutical and food labs.
- ✓Eluent Generator electrolysis cell failure and gas leakage — Membrane degradation, pressure transducer faults, or water purity drift cause KOH/MSOH generator malfunctions. Accumulated minerals from non-deionized water and thermal stress on polymer membranes shorten cell lifespan.
- ✓UV-VIS detector lamp failure and reduced sensitivity — Deuterium or xenon lamps age over 1500-2000 operating hours, reducing light intensity and causing baseline elevation. Thermal cycling and electrical stress in Indian industrial environments accelerate lamp degradation.
- ✓Thermal control module temperature overshooting and drift — Column oven and detector temperature control failure from PID controller malfunction, RTD sensor drift, or Peltier element aging. Ambient temperature variations in non-air-conditioned labs cause erratic temperature stability.

Frequently Asked Questions — DIONEX Repairs
Do you repair Dionex analytical instruments across India?+
Yes. Synchronics Electronics repairs the complete Dionex chromatography and detector range — ion chromatography (ICS), HPLC (Ultimate 3000), eluent generators, autosamplers, and all detector modules. We offer PAN India door pickup from pharmaceutical hubs in Mumbai, Pune, Hyderabad, and Ahmedabad. All repairs are performed at our ISO-certified facility in Vadodara, Gujarat, with 4-6 week turnaround for major component rebuilds.
What is the typical cost of Dionex detector repair in India?+
Dionex detector repairs range from 15,000-50,000 INR depending on fault severity. Conductivity cell replacement costs 12,000-18,000 INR. UV-VIS lamp and optical realignment runs 18,000-28,000 INR. Pump seal rebuild with pressure validation is 22,000-35,000 INR. Synchronics provides free diagnostic assessment and quotation within 48 hours of receiving your instrument. We source genuine Dionex components to ensure analytical accuracy and regulatory compliance for pharmaceutical QA labs.
Can you repair Dionex ICS ion chromatography systems with fault codes or baseline errors?+
Absolutely. Synchronics diagnoses ICS fault codes related to pump pressure, conductivity cell integrity, and eluent generator output. Common errors include low cell conductivity (indicates membrane fouling), high system pressure (valve stiction), and baseline drift (electrode aging). We perform complete system purging, cell replacement, and recalibration using certified reference standards. Post-repair, we validate anion and cation separation curves to pharmaceutical USP and ISO standards.
Do you offer warranty and calibration certificates for Dionex repairs?+
Yes. All Synchronics repairs include 6-month parts and labour warranty covering component failures and functionality. We provide ISO 17025 calibration certificates for detector wavelength accuracy, conductivity cell constant, and thermal control performance. Each repaired instrument is validated against Dionex OEM specifications and returned with performance benchmark reports suitable for regulatory submissions and audits in pharmaceutical manufacturing.
How long does Dionex autosampler and pump repair typically take?+
Autosampler needle and syringe cleaning with guide replacement takes 5-7 business days. HPLC pump seal rebuild and pressure testing requires 7-10 days. Complex eluent generator repairs with membrane replacement take 8-12 days. Synchronics prioritizes urgent repairs for pharmaceutical labs — we offer 48-hour expedited turnaround for critical instruments affecting production QA schedules. Courier pickup and delivery across India is included in repair cost.
How do I send my DIONEX unit for repair?+

What is the cost of repairing a DIONEX drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DIONEX repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DIONEX unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
