GC Product Lines We Repair
Our engineers are trained on the full GC product range. Below are the major product families we service.
GC-2010 and GC-2030 Series
Benchtop gas chromatography systems with thermal conductivity (TCD) and flame ionization (FID) detectors. Common failures include detector filament burnout, column oven temperature controller drift, and pneumatic pressure regulator faults causing inaccurate retention times.
GC-MS Detector Interface Module
Mass spectrometry coupling electronics and vacuum system controls. Typical issues: quadrupole tuning electronics failure, electron multiplier drift, GC-MS interface communication errors, and vacuum pump control board failures affecting ionization efficiency.
AOC (Autosampler/Oven Controller) Modules
Automated sample injection and temperature control units. Repair needs include stepper motor failures in autosampler carousels, temperature sensor (RTD/thermocouple) circuit faults, relay control board failures, and syringe pump electronics degradation.
FID/TCD Detector Electronics
High-sensitivity detection amplifier boards and hydrogen flame ignition systems. Common faults: detector filament failures requiring replacement, electrometer preamplifier noise or offset drift, flame ionization circuit instability, and gas supply solenoid valve failures.
Temperature Control and Pneumatics Board
Main control PCB managing column oven temperature ramp, detector temperature regulation, and carrier gas pressure. Typical failures: precision temperature sensor circuit malfunction, PID controller tuning loss, thermal runaway protection relay failures, and pneumatic valve driver shorts.
Data Acquisition and Communication Module
Signal conditioning, analog-to-digital conversion, and PC interface electronics. Common issues: noisy ADC channels affecting peak detection, RS-232/USB interface failure, chromatography software compatibility after system crashes, and real-time clock battery failures.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common GC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GC equipment arriving at our workshop.
- ✓FID detector filament burnout or baseline instability — Hydrogen flow rate misalignment or contamination in carrier gas supply causes excessive heating or filament oxidation. Extended operation without maintenance protocol acceleration. Common in Indian labs with inconsistent gas purity.
- ✓Column oven temperature controller overshoot or drift — Temperature sensor (RTD) circuit degradation, PID tuning parameters loss due to power failure, or thermal mass imbalance. Accelerated by ambient temperature fluctuations in non-climate-controlled Indian labs.
- ✓Autosampler carousel motor stall or random injection failure — Stepper motor driver IC failure, mechanical friction from dust accumulation on carousel guide rails, or syringe pump timing circuit malfunction. Common in pharmaceutical QC labs with high sample throughput.
- ✓GC-MS interface communication timeout or mass spec lock failure — Vacuum gauge sensor circuit failure, quadrupole RF drive electronics instability, or electron multiplier high-voltage supply regulation loss. Vacuum system pressure fluctuations cause loss of mass calibration.
- ✓No flame ignition in FID or intermittent flame extinguish — Flame ionization ignition transformer failure, hydrogen solenoid valve coil burnout, spark ignition electrode erosion, or gas supply regulator pressure drift below ignition threshold.
- ✓Chromatography data acquisition noise or lost peak detection — ADC amplifier stage input offset drift, analog-to-digital converter bit error accumulation, grounding loop interference from facility power distribution, or USB interface intermittent contact in aged connector.

Frequently Asked Questions — GC Repairs
Do you repair GC equipment anywhere in India?+
Yes. Synchronics repairs the full GC analytical instrumentation range — detectors, ovens, autosamplers, GC-MS interfaces, and control electronics. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other cities. All equipment ships to our central repair facility in Vadodara, Gujarat, where it receives component-level diagnostics and calibration testing.
Can you repair GC-MS detector or replace electron multiplier tubes?+
Yes. We repair GC-MS quadrupole detection systems including electron multiplier (EM) modules, high-voltage supply circuits, and mass spectrometry interface electronics. Synchronics stocks replacement EM tubes and reconditions RF driver boards. All repairs include full mass spectrum calibration (m/z 50-600) and blank run validation to confirm analytical integrity before return.
What is the typical turnaround time for GC repair and how much does detector recalibration cost?+
Standard turnaround is 7-10 working days for fault diagnosis, parts replacement, and testing. Express service (3-5 days) available for critical pharmaceutical or forensic labs. FID/TCD detector recalibration and sensitivity testing costs INR 4,500-8,500 depending on module complexity. We provide written calibration reports and traceability to NIST standards for regulatory compliance.
Our GC column oven temperature is drifting — is it the sensor or the controller board?+
Synchronics diagnoses this quickly: we test RTD temperature sensor resistance at 0°C, 50°C, and 100°C against DIN 43760 standards, then measure PID controller output voltage and heating element resistance. If sensor is <5% error, the control PCB tuning or capacitor aging is likely. Most Indian labs benefit from our preventive maintenance plan: annual sensor recalibration + PID retuning = INR 6,000-9,000 and eliminates temperature drift issues.
Is GC software compatible after we repair the control electronics?+
Absolutely. We preserve all EEPROM calibration data, reinstall original firmware versions, and test full software integration before shipping. If your PC interface was damaged, we provide USB driver support and legacy serial port conversion for older GC-2010 systems. Synchronics also advises on Windows 7/10/11 compatibility for labs needing OS upgrades — we've serviced GC instruments across Indian pharma plants running decades-old analytical methods without software conflicts.
How do I send my GC unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a GC 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 GC 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 GC 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.
