Agilent's Bet on HALO: Moving Security Screening Beyond the Shadow

NOTTINGHAM, England – July 20, 2026 – In the world of high-stakes technology, investment dollars often follow the hype. But when a seasoned analytical instrumentation giant like Agilent Technologies not only leads a multimillion-dollar funding round but increases its existing stake in a specialized startup, it signals a move grounded in strategic calculus, not just speculation. The recipient, UK-based HALO X-ray Technologies, is now poised to accelerate the commercialization of a technology that could fundamentally re-engineer one of the most stressful chokepoints of modern life: the airport security line.

The investment, supported by follow-on funding from existing backers UKI2S and the Midlands Engine Investment Fund (MEIF), provides HALO with what its CEO, Simon Godber, calls a “transformational” runway. The capital is earmarked for navigating the labyrinthine process of regulatory approval and scaling up production. At the heart of this confidence is HALO’s advanced X-ray diffraction (XRD) technology—a method that promises to move security screening from a game of shadows and densities to one of molecular certainty.

The Science of Certainty

For decades, security screening has relied on technologies that are, in essence, interpreting silhouettes. Conventional X-ray systems show the shape and density of an object, leaving human operators to make judgment calls on ambiguous items. This leads to a high rate of false alarms, triggering manual inspections that slow down lines and drive up operational costs. Even advanced Computed Tomography (CT) scanners, which create 3D images, still primarily analyze density, and can struggle to differentiate between materials with similar physical properties.

HALO’s XRD technology operates on a different principle entirely. Instead of just imaging an object, it analyzes how X-rays scatter, or diffract, when they pass through its crystalline structure. This diffraction pattern serves as a unique “molecular fingerprint” for the substance. While a conventional X-ray sees a shadow, XRD effectively analyzes the atomic lattice that casts it. This allows the system to definitively distinguish between, for example, a block of cheese and a block of plastic explosive, or harmless powders from narcotics like fentanyl, even if they appear identical on a standard X-ray or CT scan.

The practical implications are immense. Industry data suggests that XRD systems have the potential to slash false alarm rates from over 20% down to low single digits. HALO has already gathered compelling operational data from pilot deployments of its technology in major European hubs, including Copenhagen Airport and Amsterdam Schiphol Airport. For airport operators, this isn't just a security upgrade; it's a business efficiency tool. Fewer manual bag checks mean higher passenger throughput, lower staffing costs, and a vastly improved passenger experience. HALO is already packaging this capability into products like its ONYX system, an integrated CT/XRD solution, and the ARES desktop unit for resolving alarms from existing scanners.

Agilent's Analytical Ambition

Agilent's leadership in the funding round is perhaps the most telling indicator of XRD's potential. Agilent is not a traditional security hardware company; it is a global leader in analytical instruments for life sciences, diagnostics, and applied chemical markets. Their increased investment in HALO is a deliberate strategic play, extending their core competency in precise material analysis into the critical infrastructure of global security.

“Agilent’s further investment in HALO reflects our confidence in both the transformative potential of their XRD technology and the quality of its team,” said Geoff Winkett, Vice President and General Manager of Agilent’s Spectroscopy & Vacuum Division. This move aligns with Agilent’s broader strategy of embedding its advanced analytical platforms into essential, high-growth workflows.

This isn't the company's first foray into the space. Agilent previously acquired Cobalt Light Systems, another UK-based spin-out that specialized in non-invasive chemical analysis and was also backed by UKI2S. That acquisition demonstrated Agilent's appetite for technologies that can identify materials through barriers. The investment in HALO is a logical and assertive next step, betting that the same level of analytical rigor demanded in a pharmaceutical lab can be successfully applied at the speed and scale of an airport checkpoint.

A British Blueprint for Deep Tech

HALO’s journey from a university research project to a commercially-backed enterprise is a case study in the power of a supportive innovation ecosystem. The company was founded in 2012 as a spin-out from collaborative work between Nottingham Trent University and Cranfield University, turning patented academic research into a viable product. Its survival and growth through the notoriously difficult early stages—the “valley of death” for hardware-based deep tech—was made possible by investors willing to provide patient capital.

UKI2S (UK Innovation & Science Seed Fund), a publicly-backed fund, specializes in exactly this kind of long-term investment, nurturing companies born from the UK's formidable research base. Similarly, the Midlands Engine Investment Fund (MEIF) focuses on fueling regional economic growth by backing innovative local SMEs like HALO. For Godber, this continued support from investors who “know our business better than anyone” is a “vindication of our strategy.” It provides the crucial resources needed to transition from pilot programs to full-scale commercial production, a step that requires significant capital for manufacturing, quality control, and sales.

The Gauntlet of Regulation and Competition

Despite the promising technology and strong backing, the path forward for HALO is neither simple nor uncontested. The security screening market is dominated by established giants like Smiths Detection, L3Harris, and Rapiscan Systems. Tellingly, Smiths Detection has already launched its own XRD-based scanner, validating the technology's market appeal while simultaneously intensifying the competitive landscape. HALO's claim to be a pioneer is strong, but the race to capture market share is now on.

Furthermore, all security technology must pass through the gauntlet of stringent regulatory approval. Gaining certification from bodies like the U.S. Transportation Security Administration (TSA) and the European Civil Aviation Conference (ECAC) is a non-negotiable, time-consuming, and expensive process. This is precisely where the new funding will be directed. Achieving benchmarks like ECAC Standard 3 approval is the key that unlocks widespread deployment in airports across Europe and beyond.

The investment from Agilent and its partners is therefore not just a vote of confidence, but a strategic provision of the resources needed to clear these final, critical hurdles. While the technology has proven its potential in controlled deployments, its ultimate success will be measured by its ability to perform reliably, day in and day out, in the demanding, high-stakes environment of global aviation security, proving its value beyond the hype and delivering quantifiable results.
