Preventative Maintenance for LCs

Regular servicing for your chromatography system isn’t a luxury. It’s a requirement. Prevent downtime and avoid catastrophic failure with yearly preventative maintenance from ZefSci. With a responsive service team and warehouse locations coast to coast, we can guarantee your parts will be ordered and an engineer will be onsite fast to keep your instruments running.

LC Refurbishment

If you bought an LC, GC or full LCMS system aftermarket or inherited a system off-contract, our refurbishment process will ensure your equipment meets manufacturer specifications. Plus, we offer a full preventative maintenance plan with every refurbishment, so all consumables are replaced and no unexpected issues arise.

Chromatography Qualifications

We use a single, standard approach for instrument qualifications to ensure your mass specs perform to the needed parameters. Our qualifications process checks:

  • Pump flow rates

  • Injection linearity
  • Wavelength accuracy (U/V, Fluorescence)
  • Autosampler precision & carryover
