What We Offer

Expert Consulting and ‘Omics Services

At Spectrus, we take pride in being a flexible, accountable, and resourceful CRO provider for our clients’ mass spectrometry needs. Explore our solutions, instrumentation, and technology below.

Consulting Services and Method Design

Our clients have direct access to experience and insight from highly specialized experts in proteomics and mass spectrometry. Upfront consultation is invaluable for determining whether mass spec can provide useful answers, what method will generate relevant data, and how to structure the project effectively. Ongoing communication throughout each project ensures a successful outcome.

Quality and Expertise Are Essential: Having method design and sample processing done properly the first time saves money and keeps projects on track.

Cutting-Edge Sample-Processing Technology

We perform sample processing in-house using sensitive chromatography and high-resolution mass spectrometry instrumentation. Our clients rely on us for utmost precision and quality control in handling their samples. We run an efficient lab to provide a timely turnaround on samples.
