The portable platform provides rapid parts-per-billion detection across air, water, and soil, enabling faster remediation decisions, lower project costs, and real-time environmental intelligence as compared to traditional off-site laboratoriesAUSTIN, Texas, May 21, 2026 (GLOBE NEWSWIRE) -- EN-SCAN, Inc. (“EN-SCAN”), a subsidiary of Astrotech Corporation (NASDAQ: ASTC) (the “Company” or “Astrotech”), today announced the commercial launch of the Labrador HH-GC, a rugged, field-portable gas chromatograph engineered to bring laboratory-grade volatile organic compound (VOC) analysis directly to the point of investigation. As environmental regulations tighten and remediation timelines compress, environmental consulting firms and industrial operators are under increasing pressure to identify contamination faster, reduce laboratory delays, and make defensible site decisions in real time. Designed specifically for environmental consulting, remediation, industrial hygiene, and regulatory response applications, the Labrador HH-GC delivers rapid on-site detection of VOCs at parts-per-billion (ppb) sensitivity across air, water, and soil matrices — reducing the delay, uncertainty, and cost associated with traditional off-site laboratory workflows. “The environmental industry has operated for decades with a critical bottleneck: field teams collect samples, then wait days for laboratory data before making major remediation or compliance decisions,” said Thomas B. Pickens III, Chairman and CEO of Astrotech Corporation and EN-SCAN. “The Labrador HH-GC changes that workflow by placing actionable analytical intelligence directly into the hands of field operators, which we believe will enable faster decisions, accelerated remediation timelines, and considerably improved operational efficiency.” Transforming Environmental Site Investigation Environmental remediation and compliance programs frequently depend on laboratory turnaround times that can delay project execution, increase holding costs, and limit the ability to dynamically respond to changing site conditions. Based on internal tests, we believe the Labrador HH-GC reduces that delay by producing analytical results in as little as three minutes directly on-site, allowing operators to immediately identify contamination hotspots, refine sampling plans, and optimize remediation strategies in real time. The platform utilizes advanced gas chromatography paired with a high-sensitivity Photoionization Detector (PID) capable of detecting VOCs at ppb concentrations. A single instrument supports testing across multiple environmental media, reducing equipment complexity while expanding field capability. Key target applications include: <ul type="disc"><li style="margin-top:5pt; margin-bottom:5pt;">Site remediation and contamination delineation</li><li style="margin-top:5pt; margin-bottom:5pt;">BTEX detection and monitoring</li><li style="margin-top:5pt; margin-bottom:5pt;">Vapor intrusion investigations</li><li style="margin-top:5pt; margin-bottom:5pt;">Industrial hygiene and worker exposure monitoring</li><li style="margin-top:5pt; margin-bottom:5pt;">Brownfield redevelopment projects</li><li style="margin-top:5pt; margin-bottom:5pt;">Emergency environmental response</li><li style="margin-top:5pt; margin-bottom:5pt;">Groundwater and surface water screening</li><li style="margin-top:5pt; margin-bottom:5pt;">Real-time field verification during remediation activities</li></ul> Built for Field Operators, Not Laboratory Scientists Unlike traditional laboratory instrumentation requiring highly specialized operators, the Labrador HH-GC is designed for rapid deployment in real-world field conditions. The system combines rugged portability with simplified workflows and an intuitive operator interface, enabling consulting teams and remediation crews to become operational with quicker training. To support customer deployment, EN-SCAN provides: <ul type="disc"><li style="margin-top:5pt; margin-bottom:5pt;">On-site and remote operator training</li><li style="margin-top:5pt; margin-bottom:5pt;">Method development support</li><li style="margin-top:5pt; margin-bottom:5pt;">Calibration and maintenance services</li><li style="margin-top:5pt; margin-bottom:5pt;">Workflow integration assistance</li><li style="margin-top:5pt; margin-bottom:5pt;">Ongoing technical support </li></ul> All instruments include a one-year warranty and service support designed to minimize operational downtime. Positioned at the Intersection of Regulation and Real-Time Intelligence Demand for field-deployable analytical technologies continues to rise as federal and state regulators increase scrutiny surrounding VOC emissions, contaminated site management, industrial exposure, and environmental reporting requirements. Environmental firms are increasingly seeking technologies capable of reducing laboratory dependency while improving responsiveness and documentation quality. The Labrador HH-GC positions EN-SCAN to address this growing market demand by combining: <ul type="disc"><li style="margin-top:5pt; margin-bottom:5pt;">Rapid field analytics</li><li style="margin-top:5pt; margin-bottom:5pt;">Laboratory-grade sensitivity</li><li style="margin-top:5pt; margin-bottom:5pt;">Multi-matrix environmental testing</li><li style="margin-top:5pt; margin-bottom:5pt;">Reduced remediation cycle times</li><li style="margin-top:5pt; margin-bottom:5pt;">Lower project costs</li><li style="margin-top:5pt; margin-bottom:5pt;">Improved operational agility</li></ul> The instrument is available immediately for evaluation and deployment by environmental consulting firms, remediation contractors, industrial operators, and government response teams.
