Analytical Lab Services for Pharma & Environmental Applications

Written by Jen Lepore | Oct 8, 2025 1:00:01 PM

In highly regulated industries like pharmaceuticals, nutraceuticals, and environmental testing, lab data both informs current decision-making and largely determines what happens next. At Custom Processing Services (CPS), the in-house analytical lab is specifically designed to meet these demands with speed, precision, and audit-ready confidence.

In this podcast episode, CPS Business Unit Manager Willow Slusser provides expert insight into how our ISO/IEC 17025:2017 Accredited in-house analytical lab helps customers overcome testing challenges, keep pace with evolving regulatory requirements, and make informed, timely decisions.





Why In-House Lab Capabilities Matter

Being able to perform in-house testing is valuable. That might sound straightforward, but the impact is significant. With our lab integrated into the broader CPS operation, we’re able to offer rapid turnaround times, total traceability, and what Slusser explains as “actionable insights that our customers can use right away.”

Customers don’t have to wait weeks for outsourced results or coordinate between multiple vendors. Instead, they get answers quickly — with the high-touch personal service CPS is known for:

“We’re not a black box lab. We don’t just send samples and wait for a PDF. Our customers can actually talk through their challenges with scientists who understand the instrumentation.”

The CPS analytical lab is accredited to the ISO/IEC 17025:2017 standard. This signals that its equipment, methods, and personnel meet globally recognized standards for accuracy, traceability, and reliability. Customers can depend on CPS for results that will hold up to regulatory scrutiny — whether it’s the FDA, EPA, or another governing body.

3 (More) Advantages for Pharma and Environmental OEMs

Undoubtedly, an ISO/IEC 17025:2017 Accredited analytical lab is sought-after for pharmaceutical and environmental testing, but our advanced in-house capabilities further expand the benefits to our customers:

1. Simplified Compliance

Many customer challenges are compliance-driven. The analytical lab is structured to be nimble, helping customers efficiently anticipate and respond to regulatory needs before they become obstacles. The full range of advanced capabilities include:

  • Custom method development for nonstandard matrices
  • Sample preparation optimization to avoid cross-contamination
  • Trace-level detection and other in-depth analyses conducted using advanced instrumentation

2. State-of-the-Art Analysis

Complex pharma and environmental applications are held to the highest standards of precision. The CPS lab is equipped with modern instrumentation that supports defensible, high-quality results:

  • HPLC separates and quantifies actives, solvents, and degradation products
  • LC-MS/MS detects materials’ characteristics and deviations down to parts per trillion
  • GC-MS aligns with volatile compounds, such as pesticides and solvents
  • ICP-MS provides high precision elemental analysis, especially for metals
  • XRF allows for non-destructive analysis of solid materials (e.g., powders or soil)
  • Particle size analysis evaluates material consistency and performance

3. Environmental Testing Evolution

Staying ahead of rapidly changing environmental testing demands requires more than standard lab services. The CPS lab experts offer strategic guidance and fast technical adaptability in key areas such as:

  • Rapid adjustment to changes in material types, detection limits, etc.
  • Readiness in testing for microplastics, heavy metals, and more

Context. Clarity. Results.

Test results from even the most advanced lab mean little without context and clarity. CPS lab experts provide data packages that can be acted upon quickly to support R&D and quality assurance to production efficiency, and regulatory compliance.

Structured data packages support:

  • R&D batch evaluation
  • Raw material qualification
  • Regulatory filings and submissions
  • Environmental remediation or treatment planning

In turn, the information helps pharma and environmental OEMs identify and implement strategies surrounding:

  • Scale-up and production
  • Product release or delay
  • Process adjustments

Put CPS to the Analytical Test

In regulated industries, time and data quality are critical. Our ISO/IEC 17025:2017 Accredited in-house analytical lab offers a competitive edge by delivering reliable insights faster — and with the technical rigor needed to meet the highest regulatory standards.
