HPLC Product Lines We Repair
Our engineers are trained on the full HPLC product range. Below are the major product families we service.
Quaternary Pump Systems
Multi-channel pump assemblies with proportioning valve electronics and pressure control circuits. Common faults include servo drive failures causing erratic flow rates, proportioning valve board shorts leading to solvent mixing errors, and pressure transducer signal loss causing column back-pressure alarms.
Binary Pump Modules
Dual-solvent pump systems with integrated check valve electronics and flow compensation circuits. Repair challenges include pump head seal failures, proportioning solenoid coil burnout, and flow sensor circuit degradation causing gradient accuracy issues.
Detector Electronics Systems
UV-Vis photodiode array and refractive index detector circuit boards with high-gain amplifier stages. Common failures include photodiode window condensation, amplifier circuit noise from aging electrolytic capacitors, and light source lamp drive circuit failures.
Automated Injector Systems
Sample injection valve actuators, rotor motor drivers, and needle wash station solenoid controllers. Frequent issues include stepper motor stall codes, injection valve cartridge electrical contact corrosion, and sample loop microswitch failures.
Column Oven Temperature Control
Precision temperature regulation electronics with PID loop controllers and thermistor monitoring circuits. Faults include heating element relay failures, temperature sensor circuit drift causing calibration loss, and control board thermal runaway issues.
Fraction Collector Electronics
Multi-channel collection valve solenoid drivers and fraction detection signal processors. Common failures include solenoid coil opens, relay switch contact degradation, and trigger signal interface circuit noise.

Common HPLC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HPLC equipment arriving at our workshop.
- ✓Pump pressure oscillation and flow ripple — Servo pump motor drive electronics loses closed-loop feedback from pressure transducer. Aged electrolytic capacitors in the servo control board degrade, causing phase lag in the proportional valve response and pressure instability across the pump head.
- ✓Detector baseline noise and signal drift — High-gain photodiode amplifier circuits experience component aging and PCB moisture ingress. Older HPLC systems suffer amplifier capacitor ESR rise, causing baseline wander. UV lamp power supply ripple increases as output filter capacitors degrade.
- ✓Quaternary pump gradient delivery error — Proportioning valve electronics malfunction when solenoid driver transistors fail or proportional valve feedback capacitors lose capacitance. Multi-channel mixing accuracy requires precise solenoid pulse-width modulation across all four channels simultaneously.
- ✓Injector rotor motor stall and initialization failure — Stepper motor controller circuit experiences microstepping loss when commutation timing capacitors age. Rotor position feedback optical sensor window accumulates dust, causing encoder signal dropout and motor phase lock loss on startup.
- ✓Column oven temperature overshoot and undershoot — PID loop controller gains drift as thermistor aging shifts sensor resistance nonlinearly. Heating relay contacts arc internally, reducing power delivery. Temperature sensor ADC conversion noise increases when analog front-end bypass capacitors degrade.
- ✓Fraction collector valve solenoid non-response — Solenoid driver relay coil windings open internally or relay contacts fuse from arcing. Control signal optocoupler loses LED luminosity due to thermal stress. Multi-valve systems experience individual channel driver failures when boost converter output capacitors dry out.

Frequently Asked Questions — HPLC Repairs
Do you repair HPLC equipment anywhere in India?+
Yes. Synchronics repairs all HPLC analytical instrument electronics — pump drives, detectors, gradient controllers, injector modules, and thermal systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Nagpur, and all other cities. Equipment is serviced at our state-of-the-art facility in Vadodara, Gujarat. Turnaround time for non-warranty repairs is typically 5-7 working days.
What HPLC faults can Synchronics repair without factory calibration?+
We repair pump motor servo circuits, proportioning valve solenoid drivers, detector amplifier boards, injector rotor motor controllers, and column oven PID loops with full component-level diagnostics. For systems requiring post-repair factory calibration (pressure sensor offset, detector wavelength calibration), we coordinate with HPLC service centers or provide guidance for in-house recalibration using reference standards.
How do I know if my HPLC pump drive failure needs repair or replacement?+
If your HPLC pump exhibits pressure oscillation, erratic flow rates, gradient mixing errors, or servo motor stall codes, the drive electronics or proportioning valve likely needs repair. Synchronics performs free diagnostic testing to confirm whether the issue is electronic (repairable) or mechanical (pump seal/piston). Most servo and solenoid driver failures are cost-effective to repair versus full pump module replacement.
Can Synchronics repair HPLC detector boards from older instrument models?+
Yes. Synchronics has successfully repaired UV-Vis photodiode array detectors, refractive index detectors, and fluorescence detector boards from legacy HPLC instruments spanning 15+ years of manufacturing history. We source obsolete amplifier ICs, replace aged coupling capacitors, and restore detector sensitivity to specification. We maintain detailed service records and component datasheets for discontinued HPLC detector architectures.
What is the typical cost to repair HPLC gradient controller electronics versus buying new?+
HPLC gradient controllers typically cost 30-40% of a new pump module to repair. Synchronics replaces proportioning solenoid drivers, recalibrates analog proportional valve feedback circuits, and validates four-channel mixing accuracy. Most repairs cost INR 8,000-15,000 depending on component count and calibration complexity. We provide detailed cost estimates before commencing work.
How do I send my HPLC 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 HPLC 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 HPLC 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 HPLC 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.
