Compliant, Rugged Process Analytics for Pharmaceutical and Chemical Manufacturing
In regulated manufacturing, every measurement must be defensible, every data point auditable, and every sensor process-resilient. USTECH's FDA 21 CFR Part 11 compliant NIR spectroscopy platform delivers real-time process analytical technology (PAT) for raw material verification, blend uniformity monitoring, and reaction endpoint detection — without compromising safety or data integrity.
Pharmaceutical and chemical manufacturers operate under the most stringent quality and safety regulations in any industry. Zero-tolerance quality margins, explosive atmosphere classifications, and audit-ready data documentation are not optional — they are the baseline. Yet many facilities still rely on offline chromatography (HPLC, GC) or wet chemistry methods that introduce hours of delay between sampling and decision-making.
Offline Testing Creates Costly Blind Spots
Traditional methods (HPLC, GC, Karl Fischer) require 1—4 hours of lab processing. Production continues blind during this window — deviations are discovered only after the batch is complete, leading to costly rework or lot rejection.
Harsh Process & Temperature Constraints
Reactor and chemical lines operate under high pressures, temperatures, and corrosive environments. Sensor interfaces must be ruggedly constructed (e.g., sapphire window, stainless steel) to ensure long-term safe deployment.
Data Integrity & Audit Readiness
GMP guidelines (EU Annex 11, FDA 21 CFR Part 11) demand complete audit trails and electronic signatures. Paper-based logs and standalone instruments without secure data management are increasingly rejected during inspections.
Process Analytical Technology (PAT) is no longer a regulatory aspiration — it is an operational necessity. USTECH solutions are designed to embed real-time analytical intelligence directly into your manufacturing workflow, replacing laboratory bottlenecks with continuous, inline measurement at every critical quality attribute.
100% Container Verification in Under 15 Seconds
Incoming active pharmaceutical ingredients (APIs), excipients, and chemical intermediates must be positively identified before release to production. Traditional HPLC identity testing is slow, destructive, and creates laboratory backlogs that delay production schedules.
USTECH's at-line NIR analyzers scan materials non-destructively — directly through transparent polyethylene bags or glass vials — using PCA/SIMCA classification algorithms. Identity verification completes in under 15 seconds per container, and results are logged automatically with electronic signatures in a GMP-compliant audit trail. This enables true 100% container inspection without sampling, contamination risks, or warehouse bottlenecks.
Know When Your Blend Is Homogeneous — Not Just When the Timer Runs Out
Pharmaceutical blending is traditionally controlled by time: "mix for 20 minutes and assume homogeneity." But blend time is a poor proxy for blend quality. Actual homogeneity depends on particle size, electrostatic charge, humidity, and fill level — variables that change from batch to batch.
USTECH's wireless, battery-operated NIR devices mount directly onto blender viewports, measuring active ingredient concentration in real time as the drum rotates. The system calculates Relative Standard Deviation (RSD) on-the-fly, transmitting results via Bluetooth to the caliX platform. When the blend reaches the pre-defined homogeneity endpoint, the system signals completion — eliminating both under-blending (failed content uniformity) and over-blending (ingredient segregation).
Stop the Dryer at Exactly the Right Moment
In fluid bed granulation, moisture is the critical process parameter. Over-drying causes brittle granules that lead to capping and lamination failures during tablet compression. Under-drying risks clumping, mold growth, and dissolution failures. The optimal moisture endpoint is a narrow window — and hitting it consistently requires continuous measurement, not periodic grab samples.
USTECH flush-mount inline probes installed directly in the fluid bed track moisture depletion curves in real time. When the granulate reaches the validated endpoint moisture, the system triggers an automatic dryer stop signal to the PLC — saving energy, protecting product quality, and eliminating subjective operator decisions.
Track Reaction Progress Without Pulling Samples
Chemical synthesis monitoring traditionally relies on offline GC or HPLC analysis — a workflow that introduces delays, consumes reagents, and interrupts reactor operations. By mounting explosion-proof NIR probes directly into reactor lines, operators track conversion rates, solvent composition, and reaction endpoints continuously.
This real-time visibility replaces time-consuming analytical loops with instant feedback, enabling chemical manufacturers to optimize reactor yield, reduce batch cycle times, and detect endpoint completion at the moment it occurs — not 2 hours later.

Rugged Process Construction
Our inline process enclosures carry IP65 ingress protection and industrial-grade construction for safe deployment in volatile solvent zones, powder handling areas, and high-temperature reactor environments.
FDA 21 CFR Part 11 Compliant Software
ProChem software maintains complete data integrity with secure user authentication, role-based access control, encrypted and unmodifiable audit trails, and electronic signatures. Every measurement, calibration change, and user action is logged and traceable — ready for GxP audit at any time.
Wireless Blender Integration
Mounting cabled sensors on rotating V-blender drums is mechanically impossible. USTECH provides purpose-built wireless NIR configurations that charge on a dock and transmit data via Bluetooth — enabling real-time blend monitoring on equipment that conventional sensors cannot reach.
Pre-Validated Calibration Workflows
caliX platform includes pre-programmed IQ/OQ qualification workflows aligned with USP <1119> and EP 2.2.40 requirements, reducing validation effort from weeks to days and simplifying audit preparation for both new installations and annual re-qualifications.
Total PAT Control from Synthesis to Dose
USTECH technology monitors and standardizes pharmaceutical quality across the entire manufacturing cycle — optimizing parameters from raw material identification to blending, granulation, synthesis, and final packaging QC.
Implement PAT with Confidence
Whether you're deploying RMID at the warehouse, monitoring blend uniformity in real time, or tracking granulation endpoints, our PAT specialists will help you design a compliant implementation roadmap — from risk assessment through IQ/OQ validation.
