Industries We Support

Our services stay consistent across sectors — what changes is the contamination risk and what’s at stake when it goes undetected.

Contamination doesn’t behave the same way in every industry. In some, a single particle can trigger a warranty claim. In others, it can bring down an entire assembly line. At COTA, we understand the specific challenges each sector faces and adapt our technical cleanliness evaluation accordingly — so you get analysis that’s relevant, actionable, and aligned with what your customers actually require.

Automotive

Meeting OEM Cleanliness Requirements at Every Tie

In the automotive supply chain, cleanliness failures don’t stay contained — they travel upstream and downstream, affecting assembly quality, warranty performance, and customer relationships. Whether you’re a Tier 1, Tier 2, or Tier 3 supplier, your components are expected to meet strict particulate limits defined by your customer.

We support automotive suppliers in:

  • Cleanliness analysis aligned to VDA 19.1 and ISO 16232
  • Validation for PPAP approvals and OEM delivery requirements
  • Root cause investigation when components fail cleanliness specs
  • Audit preparation and technical documentation for customer reviews
  • Experience with OEM requirements from Ford, Cummins, BMW,Mercedes Benz, ZF, Hella, Daimler, Navistar,Caterpillar and others

    We help you avoid rejections, rework, and the difficult conversations that come with them.

Hydraulic & Precision Components

Where a Single Particle Can Compromise System Performance

Hydraulic systems are particularly vulnerable to particulate contamination. Valves, pumps, and actuators operate under high pressure with tight tolerances — and even small particles can cause sealing failures, accelerated wear, or complete system breakdown.

We help hydraulic component manufacturers:

  • Detect contamination before it reaches the system
  • Improve the reliability and service life of hydraulic assemblies
  • Evaluate cleanliness at critical manufacturing stages

Contamination in a hydraulic system isn’t just a quality issue — it’s a reliability and safety issue.

High-Precision Manufacturing

When Tolerances Are Tight, Cleanliness Can’t Be an Afterthought

In precision machining and manufacturing, particles introduced during production — from cutting, handling, or assembly — can affect final dimensions, surface finish, and fit. Many precision manufacturers don’t evaluate contamination systematically until a downstream quality issue forces them to look upstream.

We support precision manufacturers by:

  • Identifying contamination sources in machining and handling processes
  • Evaluating cleanliness at different stages of production
  • Improving cleaning process effectiveness
  • Documenting contamination levels to support process control

Knowing your contamination baseline is the first step to controlling it.

Aerospace

No Margin for Contamination in Critical Systems

In aerospace, cleanliness requirements exist because failure is not an option. Components used in flight-critical systems, fuel management, or actuation mechanisms are subject to strict cleanliness standards — and any deviation must be documented, understood, and resolved.

We support aerospace manufacturers and suppliers in:

  • Evaluating components against high-reliability cleanliness requirements
  • Reducing contamination risk in critical applications
  • Providing documented analysis for traceability and compliance
  • Supporting validation of cleaning processes

We bring the same rigor to aerospace analysis that the industry demands of its components.

Electronics

Protecting the Performance of Sensitive Components

In electronics manufacturing, contamination can cause short circuits, connection failures, or latent defects that only appear after the product reaches the end user. As components become smaller and circuits more dense, the impact of even microscopic particles increases.

We help electronics manufacturers:

  • Control particulate contamination in sensitive assemblies
  • Evaluate cleanliness of connectors, PCBs, and precision housings
  • Improve reliability and reduce field failure risk
  • Adapt extraction and analysis methods to component geometry

Contamination control in electronics is a reliability investment, not just a compliance exercise.

Technical Cleanliness Laboratories

Already Running a Lab? We Help You Run It Better

For companies that have internalized their cleanliness testing, the challenge shifts from doing the analysis to ensuring it’s done right — consistently, repeatably, and in alignment with international standards. Method drift, blank value issues, or equipment performance gaps can quietly compromise your results without triggering an obvious failure.

We support in-house technical cleanliness labs by:

  • Validating extraction methods and decay curves
  • Improving blank value performance and repeatability
  • Providing equipment maintenance and calibration support
  • Training analysts on VDA 19.1 and ISO 16232
  • Supplying spare parts, consumables, and replacement equipment


A lab that delivers reliable results is more than a room full of equipment — it requires the right methods, trained people, and well-maintained instruments.
