At Sygnature Discovery, this is the standard we set.

Our separation sciences platform, featuring state-of-the-art SFC and HPLC technologies, is built to support your project through every stage of its journey. Whether you need a single isomer in high purity or 100 grams of a preclinical candidate, we don’t just deliver, we design the most efficient, cost-effective path to get you there.

Because for us, purification isn’t just a technical step. It’s a strategic advantage.

Our team approaches purification with the same mindset we bring to medicinal chemistry: one size never fits all. That’s why we leverage both high-performance liquid chromatography (HPLC) and supercritical fluid chromatography (SFC), switching between them or combining both based on your molecule’s physical properties and the phase of your project.

Here’s how we compare them:

Feature
HPLC
SFC

Solvent System

Organic + aqueous

CO₂-based + organic modifier

Chiral separations

Yes (longer runtimes)

Yes (faster, more efficient)

Speed

Slower

Rapid separation and shorter RT

Solvent consumption

High

Low (green and cost-efficient)

Best for…

Polar & aqueous molecules

Lipophilic, chiral, or apolar molecules

Scale-up readiness

Standard

Excellent via 30–50 mm prep columns

At Sygnature, this strategic flexibility allows us to consistently save time, reduce solvent use, and optimize resolution, from the first microgram to the last kilo.

Case-Backed Science: What This Means for Your Project

Let’s walk through what this looks like in practice, with real examples from our labs.

We’re not against GMP, in fact, when regulations require it, we’re fully supportive of making that step. But many of the activities during the transition from CRO-led preclinical to CDMO-led clinical development don’t need to be GMP from the outset.
The regulations allow for flexibility, and using it wisely can save both time and budget without compromising quality.

Our approach helps customers:

  • Deliver at scale key intermediates that feed directly into GMP processes
  • Develop GMP-ready processes in advance so the CDMO can start with confidence
  • Consult strategically to help navigate the complex “grey zone” between preclinical and clinical, avoiding over-engineering where it’s not required

By staying alongside our clients during this transition, we help ensure the journey is cost-efficient, low-risk, and primed for success.

As your project grows, so does the complexity of what needs to be purified, analyzed, and delivered. Sygnature Discovery is uniquely positioned to take you from first injection to kilo-scale preparation, with science, speed, and strategy built in.

If you’re looking for a partner who understands that separation sciences are a gateway, not a gatekeeper, we’re ready to help you move forward, faster.
