Chromatography Systems — Repair & Spares

We keep your chromatography systems running

Evotech Scientific Solutions supplies, installs and services chromatography systems for laboratories, hospitals, universities and industry across Pakistan. When an instrument goes down, our engineers diagnose it, quote the repair and fit genuine parts — most of which we hold in stock in Lahore rather than importing on demand.

On-site & workshop

Field service nationwide, or bring it to our Lahore workshop.

Traceable calibration

Certificates against reference standards, ready for audit.

Parts in stock

Common consumables and wear parts held locally.

Faults we commonly repair

Typical failures we see on chromatography systems — if yours isn't listed, we can still diagnose it.

  • Pump seal wear causing pressure ripple and flow drift
  • Check valve blockage and loss of prime
  • Injector rotor seal leaks and sample carryover
  • Detector lamp ageing and baseline noise
  • Column backpressure rise and efficiency loss
  • Suppressor failure and high background conductivity
  • Autosampler needle and syringe faults
  • GC septum, liner and column bleed issues
  • MS vacuum leaks and ion source contamination

Spare parts & consumables we supply

Genuine and equivalent parts for chromatography systems:

  • HPLC and IC pump seals, pistons and check valves
  • Injector rotor seals and stator faces
  • IC columns and guard columns
  • HPLC columns (C18, C8, HILIC, SEC)
  • Self-regenerating suppressors (SHY-A-7, SHY-C-5)
  • Eluent generators (SHRF-10)
  • Conductivity cells (SHD-6)
  • Onguard cartridges and syringe filters
  • GC septa, inlet liners, ferrules and capillary columns
  • Detector lamps (deuterium, tungsten)
  • MS filaments, ion source lenses and turbo pump service kits

Need a part that isn't listed? Send us the instrument make, model and serial number and we will identify and quote it.

How it works

Step 1

Tell us the fault

Send the make, model, serial number and a description of the symptoms — photos help.

Step 2

Diagnosis

We attend site or receive the instrument, diagnose the fault and confirm what it needs.

Step 3

Fixed-price quote

You get a written quote for parts and labour before any work starts.

Step 4

Repair & verify

We complete the repair, calibrate, verify performance and issue documentation.
