What We Do

What We Work On

Scheduled PMs, and the 6 a.m. call when nothing is working.

Mass Spectrometry Service

Source cleaning, vacuum problems, sensitivity you can't get back, calibrations that won't hold. Sciex, Agilent, Waters, Shimadzu, Thermo.

LC System Maintenance

Pumps, autosamplers, detectors, degassers, valves. Pressure that won't hold, leaks you can't find, retention times drifting on you.

Preventative Maintenance

PM intervals built around what you actually run, not a generic annual date. Kits, verification, and a written record for your files.

Emergency Response

Instrument down, samples waiting. Same-day or next-day in Northern California, and a straight answer on how fast we can reach you anywhere else.

System Integration

Getting the instrument talking to the software, the software talking to your network, and both surviving the next IT update.

Service Contracts

Full coverage, PM-only, or pay per visit. Priced on the instruments you have and how hard you run them.

How It Works

How to Get Us Out There

Three steps. No procurement maze.

1

Tell us what it's doing

Call, or use the form below. Make, model, and the symptom. The more you tell us now, the better the odds we show up with the right part in the van.

2

You get a quote

What's involved, what parts it needs, when we can be there. In writing, before anyone touches the instrument. Contract work skips this step.

3

We show up

An OEM-trained engineer does the work at your bench, then tells you what failed, what got replaced, and what to keep an eye on.

About Sierra Spectra

We Came Up Through the OEMs

Our engineers spent years doing field service for the companies that build these instruments. Same training, same tools, same service manuals. What's different is who answers when you call.

Most LC/MS problems aren't mysterious. It's a leak, a dirty source, a worn seal, a pump that's been drifting out of spec for months. We chase the actual cause instead of swapping parts until the symptom goes away, and we tell you what we found without the runaround.

We're a small shop, which is the point. You get the same engineer who was there last time, and they remember your instrument.

Our shop is in Roseville, CA, so Northern California labs get same-day and next-day response. Everywhere else, we book it and tell you exactly when we'll be there.

Common Questions

Questions We Get

The things labs ask before they call us in.

Which manufacturers and instruments do you service?

Sciex, Agilent, Waters, Shimadzu, Thermo, Bruker, PerkinElmer. Triple quads, Q-TOF, ion traps, Orbitraps, GC-MS, ICP-MS, single quads, plus HPLC and UHPLC. If yours isn't on the list, ask anyway.

How quickly can you respond when an instrument goes down?

In Northern California, same-day or next-day depending on parts. Further out it depends on flights, and we'll tell you straight. Contract clients get weekend coverage. If it's down right now, call (833) 574-3772 instead of using the form.

Do you offer service contracts, or is it all per-visit?

Both. Call us once, or put us on contract. Coverage runs from PM-only to full parts and labor, priced on what you run rather than a fixed tier sheet.

What does a preventative maintenance visit include?

Depends on the platform, but generally: wear parts replaced, source and flow path cleaned, calibration and performance checks, and a written report for your files. We set the interval on your run hours, not the calendar.

What areas do you cover?

Anywhere in the U.S. We're based in Roseville, CA, so Northern California gets same-day and next-day. Everywhere else we schedule the trip. See service area.

How do I get a quote?

Send the make, model, and what's wrong through the form, or call. You'll get scope, timing, and price in writing before we start.
